VAZ gearbox shaft dimensions

Design of manual transmission 2101

Everyone knows that the donor for the Zhiguli was the Fiat 124, widespread in Europe. It is no wonder that the transmission was borrowed from it. The standard three-shaft design with an intermediate shaft for all rear-wheel drive models of that time was modified by domestic engineers by changing the design of the synchronizers, as well as the gear ratios.

So, the resulting gear ratios for the new gearbox are:

This is the most high-torque gearbox among classic VAZ gearboxes, because it has to work with the weakest 1.2 and 1.3 liter engines. It can be easily distinguished by the number of teeth of the drive gear - there are 17 of them (2105 has 18, 2106 - 19), as well as by the speedometer drive and the absence of a reverse light switch.

To change the oil in this transmission you need approximately 1.3 liters of 80W90.

What's in your box?

And again, before you is “intelligence” about the differences between similar parts of VAZ cars, this time - the insides of gearboxes. Our “resident” continues to find out what the factory instructions are silent about... Alexey NIKOLAEV Having started repairing the gearbox (hereinafter referred to as the gearbox), the owner of a Zhiguli or Niva may encounter considerable difficulties when purchasing spare parts. There are over a dozen modifications of the boxes, and, in principle, each of them, assembled, will fit on any “classic” or all-wheel drive VAZ, which cannot be said about the details. Some gears and shafts of a 4-speed unit will not fit a 5-speed unit and may even be non-interchangeable with parts of the same type of gearbox released a year earlier. The fact is that VAZ produced gearboxes with three rows of gear ratios, designed for engines of different sizes. Let us remind you: until 1976 there was only series 2101 (I - 3.75; II - 2.3; III - 1.49; IV - 1.0; Z. x. - 3.87) for the gearbox of all Lada cars. From 1976 to 1987, VAZ 2106 and Niva were equipped with boxes with the “increased” row 2106 (3.24; 1.99; 1.29; 1.0; 3.34). The “intermediate” series - 2105 (3.67; 2.1; 1.36; 1.0; 3.53) appeared in 1979 for cars of the new VAZ 2104-2107 family. For eight years, the plant produced sets of gears of all three rows, until, finally, in 1987, KP 2101 and 2106 were abolished, and row 2105 became single, unified for the gearboxes of all Lada and Niva cars, both 4- and produced since 1985 5-speed. And finally, in 1992, VAZ finally consigned boxes 2101 and 2106 to oblivion, ceasing to make their original gears, and at the same time abandoning the distinctive markings of currently produced parts. However, old stocks remained on hand and in stores - you can pick up absolutely everything if you know how to distinguish one part from another. This is where the information below comes in handy.

Intermediate shaft

(gear block) 2101-1701050 without identification marks. There are 29 teeth on the constant mesh ring (Z1), and 15 on the first gear ring (Z2). It can be used in 4-speed gearboxes of series 2101 complete with input shaft 2101-1701026 (17 teeth).

Intermediate shaft 2121-1701050

differs from “zero first” only in the constant mesh gear (Z1). It has 28 teeth with a smaller module and a mark in the form of an annular collar (shown by an arrow). The “twenty-first” gear block can be installed in any “Zhiguli” 4-speed gearbox complete with its own (2121) input shaft, obtaining a gear row of 2106.

Intermediate shaft 2105-1701050

, marked with an annular collar on the third gear gear (shown by an arrow). It differs from the two previous ones in the first gear ring (Z2) - there are 14 teeth with a larger inclination angle than on the 15-tooth rings of shafts 2101 and 2121. On the constant gear ring (Z1) there are 28 teeth of a larger module than on shaft 2121. Of course, and the “fifth” gear block is applicable only in conjunction with its “fifth” input shaft, and only for 4-speed gearboxes.

How to distinguish gearbox VAZ 2101 from 2106

Lada 2106 BTR-21061 ›Logbook› The gearbox is also a gearbox. (Updated)

In the matter of buying a car, it was the original (it seems to me) 4-speed VAZ-2101 gearbox.

Now we find that there are still fundamental differences between traditional gearboxes. gearbox 2101 (VAZ-2101, 2103, 21011, 21061): 1st. 3.753; 2nd. 4,5,3030; 3. 1449; 4th. smooth (1000); 5. no; RF. 3,867.

Gearbox 2105 with 5 gears (VAZ-2105, 2107 and 2104): 1st. 3667; 2nd. 2,4,1; 3rd. 1336; 4th. smooth; 5. 0.801; ZX. 3.53

At this time, gearboxes 2107 (marking: 2107-1700010) and 21074 (21074-1700005) were produced and installed instead of CAT 2105. Gearbox 2107 is an analogue of gearbox 2105, the gearbox is very similar (which, see above); Fifth gear was added to the 21074 box so we have it with gear ratios

: 1-4 and rear derailleur.
see Transmission 2107 5th gear. 0.82 I also found mention of a modification to the 2106 gearbox, namely 2106-10. the gear ratios
exactly match the control points 2105 (2107), there is not much information, but perhaps this modification of the appearance of the VAZ-2105 was renamed and received the index 2105 (and later 2107). such a story

I'm downplaying the sport, it's hard to find, but it's unnecessary.

A checkpoint (on VAZ-2103/2106) 2106 -10 (a complete analogue of the 2105 gearbox) can also be installed. Later, on the factory line, they combined the classic 2105 gearbox. At the moment, they supplied either the 2107 gearbox (similar to the 2106-10 gearbox and 2105 gearbox in gear ratio) or the 21074 5-speed gearbox.

The essence of the situation is that it is difficult to get a new Pole, so that they save something, do not go for a long time, and begin to leak like knots. And what's the worst thing they have in a day with fire that you won't reach. However, the Poles are designed for engines from 1.7 to 2.0 (these were on the Polonaise). Therefore, they practically do not fit into the classics in what they install (cutting off a piece of the transmission tunnel), they do not drive for a long time, and the driving properties are improved purely personally.

Now I'll go to my own standard: The gearbox was purchased in September 2011 and in this case it was installed on the car. Gearbox VAZ-21074-1700010-23 model. Five steps ( gear ratios

see above) 5th gear What does 23 mean at the bottom of the index (marked with a blue marker on the body in the photo): Expanded as follows: 20. box for the main pair 4.1 03. modification of the inside of the box.

The same thing with Niva: if on the ancient box there was an additional number 40, then on the new one. 43. A distinctive feature of 23 modifications is the steam speed reducer 2103 (4.1), painted red.

Gearbox for interchangeability: On the rear wheels of VAZ (Zhiguli) cars, the first gearbox type 2101 was used in the first years of production. It was used for the VAZ-2101, “2102” (until 1978,” “2103” models. In 1976, a “2106” type box with different gears appeared. Since 1977, it began to be installed on the VAZ-2121. “Niva” (this option does not have a speedometer drive, since the Niva is located on the gearbox housing) At the bottom of 1979, an additional grade appeared. "2105" with an individual gear ratio. Intermediate between "2101" and "2106". This is necessary to satisfy more stringent requirements for economics, toxicity, noise of new models VAZ-2105, “2107”, “2104” and modifications.

The choice of gear ratios allowed the 2105 to be used in all conventionally built models, and since 1987 it has been equipped with what our customers have yet to do on rear wheel drive cars (Lada). Only for Niva, still use box with gear ratios

«2106».

The boxes also differ in speedometer drives, any of which corresponds as shown in the table. 2.4, specific gear ratio. Otherwise, the speedometer may deviate from the current speed. To avoid this error, if necessary, immediately replace the speedometer drive with the box, following the table. 2. Clutch housing on, In front of the fan, paint brand indicating which model the car is assigned to: number “5” for VAZ-2105, “2104”, “7” for VAZ-2107.

Currently, some Zhiguli and Niva cars are equipped with a five-speed gearbox. It is built on the basis of a four-speed, interchangeable with it in place, and differs externally in the configuration of the rear cover when the fifth gear pair is located.

All-wheel drive vehicles use VAZ-2121 gearboxes with two gear ratios: 4.3 and 4.1. Accordingly, the speedometer drives are different. When changing the transmission, as it is called, on these cars, it is extremely important that they have an even ratio on the front and rear axles.

Additional commentary on VAZ-2121 all-wheel drive vehicles. To improve the reliability and durability of the gearbox, the pinion axle was mounted in a PC with nitrided washers underneath. Because of this, the interchangeability of housings and satellites is lost. Therefore, if you want to replace the pre-1986 exhaust housing, you should install the entire set of modified parts: 2121-1802163-200 housing, 2121-1802160-10 axle, and 2121-1802161 pinion washer.

What to do when changing boxes? Remember that window 2105 is more flexible to implement. Five step box. definitely a winning change, especially for those doing long trips, but not yet very affordable. But in general, the characteristics of the device were chosen as a compromise between dynamic characteristics, efficiency and reliability. Therefore, the VAZ-2106 with the 2101 gearbox will become more dynamic, but this will affect the durability of the rear axle parts. On the contrary, the VAZ-2101 “21013” with the “2106” gearbox accelerates more slowly.

Likewise, a gearbox with a predictable gear ratio improves dynamics but "stimulates the appetite" of the car, while at the same time increasing the load on the side gears and axle shafts. Reverse shift will exhibit a certain degradation in dynamics, especially in forward transmission.

If you change the transmission when you discover that the markings have been erased, the transmission value is determined without removing it from the car. To do this, place the gear shift lever in neutral and support one of the rear wheels with a jack (the second one should rest on the ground). Turn the raised wheel 20 revolutions and in this case calculate how many revolutions the propeller shaft made. By dividing the number by 10, you can see the final drive ratio.
