Correct tuning of the Niva Chevrolet engine will increase power by 30%

We increase the power of the Chevrolet Niva engine

Owners of the Chevrolet Niva are often indignant due to the weak power performance of the engine. The article discusses some methods for improving them through modifications and tuning.

Replacing engine components

The simplest modernization of a Chevrolet Niva engine involves replacing certain parts. First you need to bore the sleeves. After this, you need to select pistons and special ring-shaped elements that have a certain size.

The next step is to equip the engine with a crankshaft with larger arms and smaller connecting rods. The result of the above actions will be an increase in engine volume from 1.7 to 1.9 liters, and, consequently, power will increase.

It is also worth thinking about increasing the volume of fuel going to the cylinders. To do this, the cylinder head is modified, namely, the intake and exhaust ports are bored, the valve is replaced with a larger one, the valve seats are bored or completely changed.

When carrying out a complete tuning of a Chevrolet engine, it is necessary to provide for changes in the fuel supply system. This indicates the need for mandatory chip tuning.

Reprogramming the electronic control unit

The most common method of engine modification is chip tuning. The undoubted advantage of this method is that it does not require significant capital investments, but at the same time it is quite effective. This is due to the fact that chip tuning does not provide for design modernization of the engine.

The essence of chip tuning lies in making changes to the existing ECU system, adjusting the entire fuel supply complex. By changing the properties of the power unit, you can achieve both a reduction in fuel consumption and an increase in power. But at the same time, it is possible to install such software in which a balance will be maintained between consumption and engine operation.

As practice shows, standard chipping can increase power by 15%. But do not forget that these operations will lead to an increase in the load on various components of the motor, which will affect its service life.

With proper work with the software, you can achieve successful optimization of engine operation, namely setting it to 110-120 hp. at the same fuel consumption.

Tuning the NivaChevrolet engine by adjusting its geometry

There is also a method of engine tuning, the meaning of which is to change its geometry and change the cylinder head. The consequence of performing these operations will be that more fuel will enter the cylinders.

Refinement of the Chevrolet Niva cylinder head.

To do this, it is necessary to increase the size of the valve, the pusher well and, in turn, increase the seats of the intake and exhaust valves. The next step is to cut out the old valve seats and increase the diameter of the pusher well. For the camshaft, we select solid pushers whose diameter exceeds 1 mm.

After the above steps, we make other valve seats. Next, we place the seats in nitrogen, and the cylinder head in the oven. Then we install the cylinder head seats.

The final operation should be the assembly of the cylinder head, and it is necessary to ensure that the valves are tight. As a result of changing the geometry of the power unit, we obtain an increase in power of approximately 15%.

Since geometry is related to performance, this means that increased recoil will be reflected in increased fuel consumption.

Application of a turbine on a Chevrolet Niva engine

When using a turbine, you can achieve a 30% increase in power. The average cost of a turbine on the market is about 60-70 thousand rubles.

The use of turbocharging increases torque at low and medium speeds, which in turn leads to increased power and improved engine efficiency.

Installing a turbine on a Chevrolet Niva.

The most common turbine used in tuning ChevroletNiva is GARRETTGT17.

Compared to the factory engine, the turbocharged engine has higher torque (50 Nm more) and 25 hp more power.

Thanks to engine modifications, car owners can use rims with a larger radius and feel great outside the city.

Technical characteristics of the injection version

Which is better - Niva carburetor or injector? Among the advantages of the carburetor Niva, it should be noted:

• Simple design of the power system. In the event of a breakdown, you can fix the problem yourself.
• Cheap service.
• Unpretentiousness to fuel quality. Many Soviet Nivas can easily “digest” even 76-octane gasoline.
• Lack of many sensors.

It would seem that the answer has been found to the question of which is better - a Niva carburetor or an injector. However, a carburetor engine has more disadvantages. Among them:

• Low reliability. Every season you need to adjust the carburetor and carry out its maintenance.
• Dependence on air temperatures. In winter, the spark plugs could easily be overfilled, making starting impossible until the spark plugs were subsequently unscrewed and dried. Also, in winter, due to condensation, the float often “stuck”. And in the summer the fuel pump often got hot.
• Greater fuel consumption.
• Less productivity. To unlock the potential of the engine, it was necessary to spin it up to high speeds.

No matter how simple and maintainable this power system may be, it requires a lot of attention. Over the course of a year of operation, you will have to rebuild the carburetor several times. A modern car enthusiast is unlikely to be happy with this situation (especially adjusting the carburetor or drying spark plugs in 20-degree frost).

Which is better - Niva carburetor or injector? This question interests many car enthusiasts. Here are the advantages of the injection Niva:

• Stable operation of the internal combustion engine. Thanks to the presence of IAC, owners have forgotten what floating speed is. For carburetor engines this was a real disease.
• Great performance. The fuel-injected Niva responds more quickly to the gas pedal.
• Less fuel consumption. We have already seen this by looking at the technical specifications. With the arrival of the injector, consumption decreased by 20 percent.
• Excellent starting in any weather. The injection engine does not flood the spark plugs, and in the summer the fuel pump does not overheat. The latter is submersible and is cooled by gasoline, as it is located in the tank.
• Reliability. Since there is no carburetor, there is no need to regularly tune it, change jets and clean it. The maximum that the owner of an injection-powered Niva can do is clean the throttle valve, but this procedure is by no means mandatory. It is recommended to do this only if the car selects high idle speeds.

What are the disadvantages of the fuel-injected Niva? There aren't many of them. Since more electronics have been added to the system, owners may experience faulty control sensors. If the car begins to consume a lot of fuel, it is worth looking at the mass air flow sensor. If the engine does not maintain normal speed at idle, the IAC may be to blame.

And if the engine refuses to start, the contact may have come loose from the crankshaft position sensor. But fortunately, these problems don't happen that often. And you can diagnose them with a simple multimeter by measuring the resistance or contact voltage of one of the sensors. Thus, breakdowns mainly concern only electronics. The mechanical part does not raise any questions.

Malfunctions and repairs of the VAZ 21213 / 21214 Niva engine

Engine VAZ 21213 1.7 l. carburetor/injection (21214) in-line 4-cylinder with overhead camshaft, Niva timing belt has a chain drive. Based on the 214 engine, the VAZ 2123 engine is produced for the Chevy Niva; the differences in adapting the block for installing a pulley in the engine compartment and mounting attachments are technically almost identical. The main differences between the VAZ 21213 engine and the 2106 are the cylinder diameter is 82 mm, the cylinder head, the Niva 21213 engine block from the 2106 is smaller in height. Among the advantages of the 213 engine, it is worth noting the presence of a chain tensioner (no need to tighten it) and hydraulic compensators (no need to adjust the valves). Disadvantages of the Niva engine - noisy, consumes oil, prone to overheating and vibrations, low resource. The motor has all the problems of the classic series, the 21213 Niva engine still heats up, troits, knocks, etc., what the problems are, for each case, are described in detail HERE, in the problems and malfunctions section.

Chip tuning of Chevrolet Niva or 21214 engine

There is no point in writing about this for a long time because the Niva chip is useless, the atmospheric engine cannot be stirred up with a chip, and all the rave reviews are nothing more than an attempt to justify a waste of money, let’s move on.

How to cheaply increase the power of a VAZ 21213 engine

The question on the agenda: how to increase the power of a Niva engine without any special tricks? The first stage is to increase the piston stroke to 84 mm using a crankshaft from a VAZ 2130, 82 mm pistons with a piston pin offset of 2 mm and we already have 1.8 liters. The second stage is to bore the cylinders for an 84 mm piston, thus assembling the 1.9 engine for the field. To fully boost the VAZ 21213 engine, you need to add a more efficient carburetor, bore the cylinder head channels (how to do this is described HERE), the intake diameter is 33 mm and the exhaust diameter is 31 mm, it is advisable to use light connecting rods, in the end we will get about 100 hp. The third stage - we build a 2 liter motor. We buy on the market a tuning crankshaft with an 88mm stroke and 84mm pistons with a pin offset of 4mm. A complete modification of the VAZ 21213 engine will be completed after installing a Nuzhdin camshaft (or an analogue) with a lift of 11.2, a light flywheel, light connecting rods and a modified carburetor, all of which will give a total of about 110 hp.

Niva engine boring options

— piston of standard diameter, increased stroke 1.8 liters. 82x84

85 hp Maximum torque

135 Nm at 3000 rpm - larger diameter piston, increased stroke 1.9 liters. 84x84 - larger diameter piston, increased stroke 2.0 liters. 84x88

16 valve engine for Niva

From time to time on forums they raise the issue of installing a 2112 engine in a Niva; this is a rather difficult and pointless task, due to the fact that 16V engines love speed and are not well suited for an SUV. If you want speed, sell your car and buy a Priora. The Niva is not suitable for high speeds and its tuning should be aimed, first of all, at increasing traction at the bottom.

What else can be done to improve?

Experts do not recommend chipping a naturally aspirated engine. You can further increase engine power if you try to increase the piston stroke. This can be achieved by installing another crankshaft with a stroke of 84 mm, suitable for the VAZ 2130

. The piston has a diameter of 82 mm, but the piston pin must be offset by 2 mm. After this, the working volume will become 1.8 liters. In the future, if you bore the block to 84 mm. with the same crankshaft, the volume will become 1.9 liters. But that’s not all, in the future you can increase the filling capacity of the working cylinders. This is achieved by boring and installing valves with an increased diameter of their plates. This operation is quite complex and requires special equipment. It is also advisable to use lightweight connecting rods and then you can have about 100 horses at the output.

Barik-CZ › Blog › Chevrolet Niva, engine tuning - the beginning

The shortest post.

After a successful project with the modification of the UAZ Patrit - 180 hp.

— we started receiving a lot of letters asking us to work on the Chevrolet Niva, so we decided to take this car for “pumping”.
Torgmash
company provided me with a practically brand new car for this purpose.

I drove a Chevrolet Niva, the car is good, but somehow it doesn’t drive at all.

Factory engine specifications:

Working volume - 1690 cm3. Rated power - 79.6 hp Max. torque - 127.4 Nm at 4000 rpm Maximum speed - 140 km/h

Made measurements on our dynamometer stand

The figures are very close to the declared ones - 77.5 hp and 116.7 Nm; in terms of torque, the car lacked about 1 kilogram (10 Nm). .The car has about 2000 km on it and has not been fully broken in yet, so this is normal.

The problem is different, if you look at the graph of power from the wheels (P wheel) and the graph of losses measured on the freewheel (P drag) - the measurement was carried out in 4th gear. It becomes obvious why the maximum speed is 140 km/h. At this point, 140 km/h - the power from the wheels becomes equal to the power of mechanical losses.

Maximum power from the wheels in 4th gear is 40 hp. - I've never seen this before

For comparison, on our completed UAZ Patriot, stage 2 of refinement

— power from the wheels in 4th gear is 143 hp.

The task is not simple, but most importantly, will the engine tuning be of interest to the owners of this car?

You must understand that no chip tuning will help here.

I have been using Vladimir’s modification (3rd stage) on my Chevrolet Niva since September 2021 (I was the first client). Having traveled 5000 km, I remain very satisfied, because... The car pulls much better, overtaking trucks on a two-lane highway has become confident without hassle; on rough terrain I practically don’t turn on the lower gear, because there is enough traction. Among the shortcomings, I can note a slightly increased consumption of 0.5-1 liter per 100 km, but the driving style has also become much more active. Also, around 3000 rpm there is an unpleasant sound from the exhaust system, but perhaps Vladimir overcame this moment by increasing the thickness of the walls of the exhaust pipe. Regarding the sound, I plan to talk with Vladimir in the spring.

Yes. That’s why I don’t understand the flirting with this bucket.

What do you care? Or is the BMW not moving either?

Yes, getting power on a Shnivy is not a problem! Install a VAZ-21126 engine or its variation with a Super-Auto motorcycle kit with a displacement of 1.8 liters. Even if you modify the standard engine to acceptable power, then answer this question: what will you do with the transmission? The Shnivy gearbox is designed for 150 Nm at the input, also the bearings of the intermediate shaft of the transfer case will probably “sag” in terms of service life, and the main pairs will not at all digest this power off-road - there is no airflow at low speeds, the load is large - the gear teeth will overheat, they will warp, and hi! So it's very interesting. If we talk about preserving the resource at the factory level, then it is unlikely that you will be able to make a Shniva that will accelerate like the Patriot in 8.5 seconds. But in general, I am for the experiment with both hands!

What can you say about this? )))

Expert opinion

Vadim. After I moved to Niva from a foreign car, it immediately became clear that the engine would need to be completed. The lack of traction in almost any gear determines that you cannot drive comfortably off-road, and the car will not perform well on the highway. I did the tuning in stages, starting with the simplest

Egor. I decided to install a turbine on the car in question. The increase in power is quite impressive, but I decided to increase the figure by installing new sports-type consumable filters and replaced the exhaust system. I will say that the difference between 80 and 100 hp. very big.

Dmitriy. Conducted a modernization of the standard engine. I’ll say right away that no amount of tuning will solve one problem - engines of domestic origin have low reliability, you have to constantly change and finish something.

Tuning the Niva Chevrolet engine - competently increasing engine power

Many Niva Chevrolet owners note one significant drawback of this SUV - the frankly weak technical performance of the engine. Having a considerable total weight, and considering that this is still an off-road vehicle, with a power of 80 hp. With. obviously not enough.

But this is not the final verdict for this car, because it is possible to refine the engine - tuning aimed at increasing power. Moreover, this can be done in several ways, or even use them all together to achieve maximum growth.

Ways to increase engine power Niva Chevrolet

The main methods of increasing the power of a Chevy Niva engine are:

• Replacement of factory components of the power unit with tuning parts, the so-called change of component geometry;
• Installation of turbocharging;
• Reflashing the electronic control unit - chip tuning;

All of these methods can help make the engine feel more lively and dynamic, as well as increase power, although they all come with a financial investment.

Replacing Chevy Niva engine components

So, the first method is engine tuning, which involves replacing some components. First of all, this concerns the cylinder-piston group (CPG) and the crank mechanism (CPM), which requires boring of the liners. All this allows you to increase the working volume and, as a result, the power indicator.

First of all, boring is carried out, allowing the inner diameter of the liners to be increased. After this, a selection of pistons and piston rings of appropriate size is made. In addition, the engine is equipped with a crankshaft with elongated arms, as well as shortened connecting rods. Thanks to this, it is possible to increase the piston stroke. All this leads to an increase in volume from 1.7 liters, which the factory Chevy engine has, to 1.9 liters.

But replacing only the crankshaft and CPG motor is not enough. An increase in volume entails the need to increase the combustible mixture supplied to the cylinders and to better ventilate them. For this purpose, the cylinder head (cylinder head) is also subjected to tuning. First of all, the intake and exhaust windows are bored, and the valves are replaced with larger ones. At the same time, the valve seats are bored out and replaced.

Boring of inlet and outlet windows

Additionally, you can completely change the exhaust system by increasing the diameter of the exhaust pipes, and also replace the catalytic converter (catalyst) with a flame arrester.

Note that design changes to the engine will entail the need to reconfigure the operation of the fuel supply system, since with standard configurations and an increased volume, there will not be enough fuel supplied to the cylinders. That is, it will still be necessary to carry out chip tuning.

All this tuning, associated with changes in geometry, allows you to increase engine power by 15% of the nominal. But it is worth noting that an increase in volume will also entail an increase in fuel consumption.

Installation of turbocharging on a Chevrolet Niva

The second method of tuning the Niva Chevrolet power plant is to install a turbocharger. Moreover, this method allows you to significantly increase power and also increases torque.

Turbocharging provides significantly better filling of the engine cylinders with air due to forced injection.

With this tuning option, you should carefully select a turbine, otherwise the positive effect of its use may be significantly lower than expected.

Tuning in this way allows you to achieve an increase in engine power by 30%. At the same time, turbocharging only has a positive effect on fuel consumption, since it is reduced. And the increase in power is achieved due to better fuel combustion and ventilation of the engine cylinders.

Reflashing the ECU on a Chevrolet Niva - chip tuning

And the last way to increase the power of a Chevrolet Niva SUV is chip tuning. Moreover, this method is the most inexpensive among those available, since the technical part of the motor is not subject to any processing.

The whole essence of such tuning comes down to replacing and adjusting the software of the electronic control unit (ECU), which regulates the operation of the fuel supply system.

An interesting fact is that during flashing, you can change the operation of the ECU in different directions - reduce fuel consumption due to the dynamic and power indicators of the engine, or vice versa - increase power, but as a result, consumption will increase. You can choose parameters that will be optimal both in terms of performance and gasoline consumption.

It is worth noting that it is quite enough for the engine to only be chipped to increase power, up to 15% of the rated power unit of the Niva Chevrolet. In this case, there is no need to perform any modifications to the engine. But there is also a small drawback to this.

Drawing conclusions

When looking for an affordable off-road SUV, many pay attention to this particular offer. However, it is worth considering that the installed motor first requires repair, and then significant modernization. Lack of power off-road becomes the reason why the car cannot overcome difficult areas. There are quite a large number of ways to increase power, they all have their own specific characteristics.

Some modifications can be done independently, others require the intervention of professionals. Note that the power increase is 20 hp. - a completely achievable task without serious intervention in the design of the motor. Of course, many improvements will require significant investments. An example is the installation of sports filters, which are much more expensive than regular filters.

Tuning Niva, Niva Chevrolet

Many Niva and Chevrolet Niva owners sooner or later think about improving some of the qualities of their car. This could be something minor - aimed, for example, at changing the appearance (decorative thresholds, ventilation trims, spoilers, deflectors, fly swatters, etc.), or it could be something very serious related to changing the design of the car, modification transmission components, engine, suspension...

Regarding SUVs, and it is this category that the Niva and Niva Chevrolet cars belong to, questions most often arise regarding the improvement of off-road qualities. We will try to cover this topic in more detail. Everything that will be written about in this article is based solely on our experience in tuning Niva cars, and we start from the tasks that our clients set for us.

So, off-road tuning. It all starts, as usual, with something simple. You buy a car and after gaining some experience in off-road driving (fishing, hunting), you understand that if you put on mud tires, which are tougher, and even larger in diameter, then the car will drive more confidently in the mud and will drive further. And if you install self-blocks, it will be even cooler... And this process is drawn out, because every round of tuning, every new modification gives an additional advantage on the roads, and this in turn causes a feeling of deep satisfaction in Nivavod.

Leaving the lyrics aside, let's try to highlight the main approaches to modifications of Niva and Chevrolet Niva cars:

1. Light. Includes: installation of high-quality engine protection and possibly gearbox; mud tires, perhaps a little larger than standard, for example 215/75 R15, but then a minimal lift will be needed; a screw self-block in the rear axle would not interfere; Well, upload another ECU firmware, because... The stock car doesn't drive very well...
2. Optimal. What many clients end up with: Suspension lift of about 5 cm; cutting arches; installation of expanders; mud tires 29-30 inches; replacing the main pairs in the transmission with 4.3 or 4.44; blocking in axles, at least in the rear; power bumper + winch; snorkel; breather output; engine firmware, at a minimum, at a maximum, an increase in engine volume with accompanying modifications; It is also possible to install an expeditionary trunk with a chandelier...
3. Hard. Everything that is cooler than described above: Extreme wheels from size 31 and uphill; strengthening everything that can be strengthened; clear modification of the engine; deeper modification of the transmission, etc.

It must be said that the third approach is not often chosen; as a rule, these are people keen on competitions or extreme off-road expeditions. For a fisherman, a hunter, or for weekend off-road rides, the improvements listed in the second paragraph are more than enough.

Good luck off-roading! Best regards, Niva-Profi team.

Modification of the motor: replacement of the throttle and standard filters

All fundamental improvements to the classic SUV in question are primarily aimed at significantly increasing its cross-country ability. Not only the ground clearance and the features of the installed all-wheel drive system determine how high the cross-country ability of an SUV is. In the absence of proper traction, the car will simply stand on a difficult section of the road and will not move. That is why the possibilities of increasing the thrust of the installed engine or replacing it completely should be considered.

Many people consider installing a turbine to be the most effective way to modify an engine.

When considering this option for improving the motor, you should pay attention to the following points:

• The cost of a turbine can vary over a fairly wide range. In the store you can find offers for 40,000 rubles or so.
• Do not forget that installing a turbine yourself is quite difficult. As a rule, such tuning involves the involvement of specialists, due to which the cost of work increases significantly.
• Mistakes made during turbine installation can lead to a fairly large number of different problems.
• A turbine is not always the ideal solution to increase the power of an internal combustion engine. If the engine itself is in poor technical condition, then the turbine can aggravate the current situation to an even greater extent.

When considering simple ways to increase the thrust of a standard engine, attention should be paid to the possibility of replacing standard filters and choke. You can significantly increase the efficiency of the installed engine by replacing standard filters

The important points include the following information:

You can significantly increase the performance of an installed engine by replacing standard filters. The important points include the following information:

• Standard filters are not very efficient. In addition, they create additional resistance to the fuel current, due to which the efficiency value drops significantly.
• To increase power, it is recommended to purchase sports filters, for example, from the manufacturer Pro Sport. They have increased efficiency and can significantly increase engine output.
• Filters are consumables that should be replaced periodically. If wear is too high, the structure no longer retains foreign elements.

The filter replacement process can be characterized as follows:

When choosing a filter, you should pay attention to the fact that the mounting diameter should be less than 75 mm. To remove the old filter, all pipes and the throttle channel are disconnected and the standard protective cover is dismantled. You can eliminate the possibility of rapid wear of the structure by blowing out the seat. It should be borne in mind that a fairly large amount of debris may remain after the old product.

If it gets into the system, it can damage the filter. The tightness of the joint can be increased by adding motor oil to the joint. The throttle is switched off. It is located directly under the filter itself. Disconnection is carried out by turning off the fuel system channels and air supply.

Considering the features of replacing the throttle, we note the following points:

• It is recommended to give preference to dampers with a diameter of 52 mm. This kind of device can pass a fairly large amount of air, due to which the power of the installed engine increases by 18%. With such a high rate of increase in power, the cost of modification is relatively low.
• To install a new damper, the old one must be removed. As a rule, there are no problems with carrying out such work.

Due to such minor modifications, the power of the installed motor can be significantly increased. Greater traction makes it easier to overcome holes and various obstacles.

Tuning of Niva and Chevrolet Niva cars

Car tuning is the modification of individual parts in order to improve any functions or appearance. Both body and interior elements, as well as working components and assemblies can be subject to tuning, which will improve the technical characteristics of the car.

If we are talking about tuning Niva and Chevrolet Niva cars, then in this case the meaning of the modification is rather to improve driving performance, expand the ability to overcome off-road conditions and strengthen individual components. Most often, Niva owners resort to tuning, using their cars for hunting, fishing, and to participate in rally competitions. The Russian SUV is also popular among residents of country houses, who every day have to deal with roads that are not of the best quality.

What tuning is most popular for Niva and Chevrolet Niva cars

Strengthening the side members

On used Niva cars, upon inspection, you can often notice the presence of cracks on the side members. This may be the result of heavy loads when driving off-road, as well as exposure to corrosion. To prevent critical deformations of the load-bearing elements of the body, reinforcement is performed with steel sheets 3-4 mm thick. If springs or shock absorbers with increased rigidity, large-diameter wheels, power bumpers and winches are installed on a car, reinforcement of the side members is mandatory. It is not uncommon for a car that has come to the aid of another car, which often happens at jeep trial competitions, to simply have part of its body torn out. This can happen if the side members have not been strengthened. The winch itself and its attachment to the reinforced bumper are stronger than the factory design.

Reinforcement of the rear axle

Rear axle deformation is also a fairly common problem. The reason for this may be excessive load or impacts when conquering off-road conditions. When operating a car with a broken rear axle geometry, accelerated wear of the tires occurs, and deviations from the straight trajectory are also possible. To strengthen the bridge, a steel profile (channel or angle) is welded on both sides of the stocking. The stocking itself is also scalded with plates or a profile to provide access to the filler hole.

Additional protection of units

Driving off-road is always associated with the risk of contact of the bottom of the car with the ground, tree roots, and stones. In this case, impacts may occur on the lower parts of the main units. To prevent damage to them, additional metal protection is installed for the engine crankcase, transmission and transfer case.

Second step: turbocharging

The next point of modification of the power plant is the installation of turbocharging. Even as a stand-alone procedure rather than a comprehensive procedure, this method can significantly increase power and torque.

With the help of this element, the engine cylinders are better filled with air, according to the forced principle.

But you should choose a turbine very carefully. Otherwise, the expected effect will be very different from the one obtained.

A correctly selected and installed turbocharger allows you to increase engine power by 30%, without having a negative impact on fuel consumption. In combination with the previous method, the percentage of improvement increases.

Step-by-step instructions for do-it-yourself disassembly

Beading using montages.

For the work you will need mounting kits, which can be purchased at any specialized store. Let's look at the step-by-step sequence for removing a tire.

• Remove the wheel by unscrewing the nuts that secure it to the bicycle frame. In modern bicycles this can be done without much difficulty, since they are equipped with a quick-release mechanism. In other cases, WD-40 will help.
• Unhook the brake pads. When working with the rear wheels, you need to switch to lower gear and remove the chain from the sprocket.
• Press the valve on the nipple, lowering the wheel all the way. In the case of a tubed tire, it is necessary to completely unscrew the nipple, pull the tubed “nipple” out, and then remove the tire.
• Insert 2 mounting blades under the tire at intervals of 10-15 cm.
• Take 1 spatula and carefully move it around the circumference in the direction opposite to the other spatula.
• Remove the tire.

Important! After removing the tire, you need to inspect it externally, the tubes and wheels for defects and damage, check for protruding spokes or other sharp objects on the rim that need to be removed

Camera repair after disassembly

The tire has been removed. Now the wheel needs to be checked. If damage is detected, a decision is made as to whether the tubes and tires need to be replaced or repaired. In the first case, to restore the integrity of the wheel, you will need a set of bicycle tools. The procedure for sealing a bicycle inner tube is as follows:

• pump some air into the chamber and immerse it in water: air bubbles will be visible at the hole;
• wipe the camera dry, clean the puncture area with sandpaper;
• spread glue on the puncture site, glue the patch, place it under the press;
• After the glue has dried, perform a test inflation of the tire and check whether it is leaking air.

Now that we have made sure that the tube and tire are in order, we can begin the reverse process - beading.

Oil pump work

Lubricant supplied through the oil pump extends engine life. To improve the performance of the oil pump when tuning the Niva engine, you need to take another pump and cut off part of the housing with the parting plane from it. The thickness of this “pancake” should be about 11 cm. Using milling, cut off the excess and leave a thickness of 10 mm.

Next, do the following to remove chamfers on the edges of the teeth:

1. We compress, that is, remove, the drive gears.
2. We trim one of the gears by 0.75 mm on each side.
3. We cut the second gear to 11.5 mm (after trimming).
4. We repeat the operation with the remaining gears (driven).

Let's start working on the body. To do this we do the following:

1. We release the driven gear axis from the housing.
2. We form a longer axis from the drive roller.
3. We insert the resulting axle into the body.
4. We press the narrow gear onto the second drive shaft.
5. Press on the wide gear.
6. We fix the wide driven gear in the housing.
7. We install a narrow gear into the housing.

This sequence will prevent the gears from turning relative to each other. You can also improve the oil receiver of the Vase by cutting it a centimeter from the bottom. After this, we adjust the end gap and connect the entire structure with bolts.
