Communities › Nivaclub › Blog › Bridges and axle shafts, Niva and Shniva, types and varieties.
Not long ago I had an unsuccessful jump and bent the bridge, and the fact that the bridge was bent was only seen, naturally, when the axle shafts were taken out.
And since they were dismantling the car for a different topic, the bridge, firstly, came as a surprise, and secondly, and most importantly, we had to urgently find a new one, even one, so that the car would not take up space in the service. And since I have a Niva, and not a Geledvagen, we gathered across the bridge not to the store with a list of articles, but to sort it out. And there, over the phone, they promised a wide bridge, but on the spot it turned out to be narrow, and under the guise of a short one, they sold a bridge from the classics.
There was no fundamental difference which bridge to install, but it was necessary to immediately decide on alterations and a list of spare parts that also needed to be purchased immediately, I decided to organize the information about what bridges fit what.
Globally, there are three (four) types of bridges - narrow, wide and shnivo bridge, m-bridge:
The narrow 21st axle is the rear axle beam 2121 (2121-2401010).
Length 1330 mm. Locking ring 21 (2121-2403084) and oil seal 01 (2101-2401034).
Axle shaft 2121 (2121-2403069) - it’s short, it’s also the old model - length 750 mm.
Installed before 2002-04. Afterwards, unification with the shnivy took place and the plant stopped making short axle shafts. Wide axle – rear axle beam Niva 213 (21213-2401010) and Shniva 2123 (2123-2401010)
- essentially the same, they differ in the fastening of shock absorbers (which are like a house in the field) and brake pipes. Length 1350 mm. Locking ring 2123 (2123-2403084 regular or with teeth 2123-2403084-10 for ABS), oil seals 2110 left and right (2110-2301034 and 2110-2301035).
Niva axle shaft (21213-2403069) and shniva (2123-2403069) – it’s long, it’s also a new model – 760 mm. The axle shafts themselves are the same; the assembly differs in the mounting bolts (M10x60 for 2123 and M10x50 for 213) of the axle shaft to the bridge. Now only shniva axle shafts (2123-2403069) are produced.
Externally, a narrow bridge differs from a wide bridge by the groove for the locking ring - ring 2123 will not fit into the narrow bridge, ring 21 will, in principle, fit into the wide bridge. The difference between the axle shafts is in the place for the oil seal. The short one, after the locking ring, transitions to a smaller diameter of 30 mm. The long one does not have such a transition; the place for an oil seal with a diameter of 35 mm is the same as under the locking ring. and as suggested in the comments, there is also a visual difference - in the area where the axle shaft is attached, the new wide bridge has a square boss, but the old one does not.
Installed approximately from 2002-04 to 2009.
M-bridge - rear axle beam 214 (21214-2401010).
The same wide axle, but the shock absorber mountings have changed - now vertically - and the mounting brackets for the long rods have been changed. The rods are brought together to the axis of the car, respectively, the brackets are turned 5 degrees.
Long axle shafts 2123.
Installed around 2009-10.
Also in nature there is a bridge 2120 (2120-2401010 and 2120-2401010-20) narrow and wide, respectively, and axle shafts for it 2120 (2120-2403069 and 2120-2403069-10). We bet on Nadezhda and on various crocodiles. They are considered to be stronger than regular ones.
And the fickle MythBusters column.
Myth 1.
The classic and 21 Niva have the same bridges.
Bridge 2106 (2101-2401010). Width 1250 mm, i.e. 8 cm narrower than Nivovsky. The cups for the springs are also located a little narrower, the rest of the fasteners are the same and are completely interchangeable. I haven’t seen a classic bridge on the field, but rally drivers use a wider bridge and thicker axle shafts on the classic ones.
Destroyed. Myth 2.
There are axle shafts with 24 splines.
They really do exist. According to legend, they were developed and installed at FAM Niva. However, the factory never actually made 24-spline axle shafts and never installed corresponding differentials in the rear axle. Neither on the field, nor on the shniva. Another thing is that no one bothers you to install a side gear with 24 splines and use non-factory axle shafts. But no one is stopping you from rolling in the military bridge either.

Technical characteristics of the standard seven engine
The usual volume for a VAZ engine is one and four cubic centimeters. However, this volume throughout the production of power units ranged from one and a half to 1.8 liters. The power of the standard engine started at 71 horsepower.
More detailed technical specifications are given in the table below.
| Parameter | Meaning |
| Nutrition | Injection or carburetor |
| View | Row |
| Pistons (pieces) | 4 |
| BC | Cast iron |
| cylinder head | Aluminum alloy |
| Piston stroke | 80 mm |
| Cylinder diameter | 76 mm |
| Torque | 104 Nm |
| Compression ratio | 8,5 |
| Oil quantity | 3.7 l |
| Volume in cubic cm. | 1452 |
This engine for the VAZ 2107 has been produced since 1972. And in our time it is produced at Russian factories.
When choosing a different engine for installation on a VAZ 2107, you need to carefully consider the dimensions of the power unit. The dimensions should match the old engine so that you don't have to remove anything or trim metal. These are unnecessary problems and financial costs, unless, of course, you are an experimenter.
Is a classic bridge suitable for the field?

Leverage
All SUVs actively use all their resources, including the front axle. At the same time, Niva manages to use such resources as people’s nerves. In addition to the familiar gear shift lever and handbrake, Niva boasts another lever that serves to control the transmission - downshift, return to upshift, lock and unlock the differential. At the same time, those who got behind the wheel of this car for the first time may have big problems - after engaging a lower gear, the lever does not want to return to an upshift! The secret is that return is only possible with the clutch depressed and at low speed. Some drivers neglect the instructions and remain unaware of the generally accepted method. Through trial and error, they figure out that shifting is possible when driving in reverse in a circle at extremely low speeds. And although this method works, its convenience is highly questionable.

How to change?
If the mechanism is seriously damaged, it makes sense to replace it with a new one. To do this you will need a new gearbox and a small set of tools:
Important: replacement or repair of the gearbox cannot be performed without a lift, inspection ditch or overpass.
Operating procedure
To install the new unit in place, you must perform the operations in reverse order.
Important: after installing the gearbox, do not forget to fill it with transmission oil. Otherwise, you will soon have to change it again with another one

I propose in this topic to post developments on one of the most complex, but very tempting topics: Options for manufacturing a front drive axle on a classic. It’s no secret that many people do fractures only because it’s easier to do all-wheel drive. But if there is a problem, there must be a solution.
About the current issue: The thought of rolling the front axle into my Beetle haunts me; our terrain is hilly, and you can’t go very far on one bridge. If I don’t come up with anything, I’ll do a break, but for now I have time to rack my brains. So I’m puzzled, maybe someone can tell me: How and what to make the front drive axle from so that the track remains within 900mm? Well, would you like a larger turning radius?

How and from what should the front drive axle be made so that the track remains within 900mm?
I made swivel units from the Moskvichevsky bridge on crosspieces; now it’s easier to install CV joints from front-wheel drive cars; back then there weren’t any.
Well, would you like a larger turning radius?
The radius will also depend on the base of the tractor; everything should be within reason, but not at 90 degrees.
General information
The latter will be discussed in the article. The front axle of a passenger car can be different in design, but in cars like Niva-Chevrolet, the front axle is continuous and rigidly connected to the crankcase, since the car is equipped with permanent all-wheel drive. The main advantage of a continuous axle is that due to the rigid fixation, the tires wear out much less, but at the same time all the vibration from the wheels is transferred to the car.
Even such an element as the front axle can help you stand out; Niva used all its resources - unlike the rear axle, the front axle is not only driven, but also steered. The cross-country ability of both cars under consideration, the Chevrolet Niva and Niva 2121, makes many prestigious “SUVs” envious, since many modern cars, although called SUVs, do not have permanent all-wheel drive.
