Do-it-yourself UAZ bridge repair

In detail: do-it-yourself uaz bridge repair from a real master for the site my.housecope.com.

UAZ 3741 is a four-wheel drive domestic utility vehicle, produced under the name UAZ 452 in Soviet times. For its characteristic body shape, it received the popular nickname “loaf”. In the factory configuration, it has an all-metal body, leaf spring suspension and 2 drive axles with non-locking differentials that transmit power to all 4 wheels.

Rear-wheel drive is permanent, front-wheel drive is plug-in. The bridges are unified with the UAZ 31512. Carrying capacity - 850 kg. Clearance - 220 mm. Repair of the front axle of the UAZ 3741 is extremely rare, since its design is quite reliable. Basically, it all comes down to replacing the wheel bearings and oil in the differential, ball and pivot pins. But sometimes it is necessary to remove the bridge. And you have to do it yourself, since UAZ service centers are far from everywhere.

Since the UAZ 3741 has a frame structure, it is quite easy to remove the front axle. To do this, you need to stock up on a powerful jack, stops that can withstand 1.5 tons of the weight of the front of the car, and a special liquid for unscrewing the nuts - WD-40.

First, you need to substitute stops under the rear wheels.
Then you need to disconnect the right and left brake pipes from the rubber hoses that go to the front wheel brake drums.
After that, unscrew the nuts securing the brake hoses and remove the hoses themselves.
Next, you need to unscrew the nuts that secure the lower ends of the shock absorbers.
After that, it is necessary to unscrew the bolts connecting the front universal joint with the drive pinion flange.
Then you should unpin and unscrew the nut of the ball pin of the bipod.
Next, you need to disconnect the rod from the bipod.
Now you need to unscrew the nuts securing the stepladders of the front springs, remove the stepladders along with the linings and linings.
At the end, lift the front of the car by the frame and pull the axle out from under the car.

After the old bridge has been removed, you can proceed with the installation of the new part by performing the steps in reverse order. If necessary, the removed unit is disassembled, troubleshooting is carried out, damaged parts are replaced and the bridge is installed back.

The most common reason for the inappropriate behavior of the UAZ 3741 vehicle on the road is the violation of the axial clearance of the pivots. It is very simple to check whether it is broken or not - just raise the front end with a jack and try to swing the wheel up and down. If end play exists, the pivot clearance should be adjusted.

The adjustment is carried out as follows.

We raise the front of the car, having previously put the car on the handbrake.
We dismantle the wheel.
We unscrew the bolts securing the ball seal.
We check the axial play by shaking the structure up and down with our hands.
We unscrew several bolts securing the upper lining of the king pin. Remove the cover.
We take out the thinnest shim and put the pad back.
We carry out the same procedures with the lower pad of the king pin.
We tighten all the bolts and check the result. If the backlash is eliminated, screw the oil seal and the wheel back on and go. If the backlash remains, we adjust everything again, this time removing the thicker gaskets.

It is important to pull out equally thick spacers at both the top and bottom to maintain the alignment of the CV joint. If the alignment is broken, expensive repairs will have to be done after a while.

Assemble the differential in the following order:

1. Before assembling the differential, lubricate the side gears, satellites, thrust washers and pinions with gear oil.

2. Install thrust washers on the axle shaft gear journals.

3.Install the side gear with thrust washer assembly into the left-hand satellite box.

4. Install the satellites on the axle of the split cross-piece.

6. Install the side gear with thrust washer assembly into the right gear box. Keeping the semiaxis gear, install the right cup of the satellites on the left so that the marks (Fig. 2) (serial numbers) of both cups are aligned.

7. Bolt the halves together and tighten. Tightening torque 32–40 Nm (3.2–4.0 kgf).

8. Install the final drive gear on the planetary gear box, aligning the bolt holes. Install the bolts and tighten. The tightening torque is 98–137 N · m (10–14 kgf · m). At the assembled differential, the gears of the semi-axles must be turned using a spline mandrel from a force of no more than 59 N (6 kgf) applied at a radius of 80 mm. Adjust the differential bearings (if replaced) in the following order:

UAZ 3741 - This is a four-wheel drive domestic utility vehicle, which in Soviet times was produced under the UAZ 452 index and for its characteristic body shape is called "Loaf". In the factory configuration, the car has an all-metal body, as well as a leaf spring suspension and two drive axles with non-locking differentials that transmit power to all four wheels.

Front-wheel drive is plug-in, rear-wheel drive is permanent. The bridges are unified with the 31512 model. The Loaf's carrying capacity is 850 kg. The ground clearance is 22 cm. Repair of the front axle 3741 is extremely rare, since its design is quite reliable. Basically, the repair is reduced to replacing the wheel bearings, as well as the oil in the differential, pivots and ball bearings. However, sometimes it is still necessary to remove the bridge. You have to do this yourself, since UAZ service centers do not work everywhere.

Since the UAZ 3741 has a frame structure, the front axle can be removed quite easily. To do this, you need to stock up on a powerful jack, stops that can withstand 1.5 tons of the front of the car, and WD-40 - liquid for unscrewing the nuts.

The procedure is as follows:

First, you need to install stops under the rear wheels of the car.
After that, disconnect the left and right brake pipes from the hoses that go to the front wheel drums.
Then you need to unscrew the nuts securing the brake hoses and remove the hoses themselves.
Next, unscrew the nuts securing the lower ends of the shock absorbers.
Remove the bolts connecting the pinion flange c. front cardan.
Then you should unpin the cotter pin, unscrew the nut of the ball pin of the bipod.
Disconnect the link from the bipod.
Unscrew the nuts that secure the ladders of the front springs, and remove the ladders with pads and linings.
At the end, you need to lift the front of the car by the frame and pull the bridge out from under the car.

When the old bridge has been removed, you can proceed to the installation of the new part by performing the reverse procedure. If necessary, the removed unit is disassembled, its troubleshooting is carried out, damaged parts are replaced, and then the bridge is returned to its place.

Most often, the cause of inadequate behavior of the car on the road is a violation of the axial clearance of the pivots. It is very simple to check its violation - you just need to raise the front end with a jack and shake the wheel up and down. When axial play is detected, the pivot clearance needs to be adjusted.

Adjustment steps:

We lift in front of the car, after placing the car on the handbrake.
We dismantle the wheel.
We unscrew the ball bolts securing the oil seal.
We check the axial play by swinging the structure up and down.
We unscrew a few bolts of the upper lining of the king pin and remove the lining.
We take out the thinnest gasket, put the pad back.
We carry out the same actions with the lower pad of the king pin.
We tighten the bolts and check the result. When the backlash is eliminated, we screw the wheel and the oil seal back - and we go. If there is still play, adjust it again by removing the thicker spacers.

Adjustment of the clearances in the gearing of gears and in the bearings of the drive axle of cars of the carriage layout of the UAZ-3741, UAZ-3962, UAZ-3909, UAZ-2206, UAZ-3303 is performed only when replacing gears or bearings, or when the axial clearance of the driving or driven gears of the main transmission. Replacement of the main drive gears should be done only as a complete set.

Adjustment of the bearing of the drive gear of the main drive of the drive axle UAZ-3741, UAZ-3962, UAZ-3909, UAZ-2206, UAZ-3303.

It is necessary to adjust the bearing of the driving gear of the main drive of the driving axle by selecting the thickness of the package of shims and tightening the flange nut. The bearing must be preloaded so that there is no axial movement of the pinion gear and the pinion rotates by hand without much effort.

Check the bearing preload with a dynamometer. In doing so, detach the left half of the crankcase. Remove the pinion bearing cover so that the friction of the oil seal does not affect the dynamometer readings. With correct adjustment, at the moment of turning the drive gear by the hole in the flange, the dynamometer should show a force of 1.5-3 kgf for worn-in bearings and 2.0-3.5 kgf for new bearings.

When putting the cover back in place, line up the lubrication holes in the crankcase, gasket and cover. The tightening torque of the pinion flange nut should be 17-21 kgcm. You cannot even unscrew the nut a little in order to achieve the alignment of the cotter pin hole with the slot in the nut. If the nut is not tightened sufficiently, the inner bearing rings can turn and, as a result, wear of the shims and the appearance of a dangerous axial clearance.

If the axial clearance of the drive gear appears during operation of the vehicle, tighten the flange nut. If this does not eliminate the axial clearance, then reduce the thickness of the shim pack and adjust the bearing as described above.

After adjusting, observe the heating of the bearings while driving. A slight heating of the bearing is not dangerous, but if the throat of the drive axle housing heats up to a temperature of 90 degrees and above, water boils on the crankcase, this means that the bearing has been overtightened and the total thickness of the gaskets should be increased.

Differential bearings must be adjusted by selecting the thickness of the package of shims installed between the ends of the inner rings of both bearings and the satellite box. When replacing the main gears and differential bearings, adjust in the following sequence:

1. Press the inner rings of the differential bearings onto the journals of the assembled differential so that there is a gap of 3-3.5 mm between the ends of the planetary gear box and the ends of the inner rings of the bearings.

2. Remove the axle shafts and install the differential assembly with the driven gear into the crankcase, put the gasket and the cover, tighten the cover bolts and turn the driven gear with a mounting blade through the crankcase throat, roll in the bearings so that the rollers take the correct position. Then, using fasteners, evenly and finally connect the cover to the crankcase.

3. Unscrew the fasteners again.Carefully remove the cover, remove the differential from the axle housing and measure the clearances A and A1 between the ends of the satellite box and the ends of the inner bearing rings with a feeler gauge.

4. Select a package of gaskets with a thickness equal to the sum of the gaps A + A1. To ensure preload in the bearings, add a 0.1 mm shim to this package. The total thickness of the package of gaskets should be equal to A + A1 + 0.1 mm.

5. Remove the differential bearing inner races. Divide the matched pack of shims in half. Install the gaskets on the journals of the planetary gearbox and press the inner bearing races against the stop. After that, adjust the side clearance by moving the driven gear.

When replacing only the differential bearings, measure and compare the height of the new and old bearing assembly. If the new bearing is higher or lower than the old one by some value, then the thickness of the existing package of gaskets should be reduced in the first case and increased in the second case by the same amount.

Adjustment of the side clearance and position of the main gears of the drive axle UAZ-3741, UAZ-3962, UAZ-3909, UAZ-2206, UAZ-3303.

The adjustment of the side clearance and the position of the main gears should be done only when replacing old gears with new ones in the following sequence:

- first adjust the pinion bearings and differential bearings as described above,
- then proceed to adjust the lateral clearance in the meshing of the teeth of the main drive gears.

The lateral clearance in the engagement of the gears must be adjusted by rearranging the shims from one side of the differential box to the other. If you remove the gaskets from the side of the driven gear, then the clearance in the engagement increases, but if you add, the clearance decreases. The gaskets only need to be rearranged without changing their total thickness, so as not to disturb the tightness of the differential bearings.

The circumferential side clearance should be between 0.35-0.77 mm. Measure on the flange of the drive gear at a radius of 40 mm, check in four positions of the drive gear every revolution. After completing the assembly of the drive axle, it is necessary to check its heating after the movement of the car.

If the heating of the crankcase in the area of the double-row tapered bearing, the drive gear or differential bearings is over 90 degrees, the water boils on the crankcase, then the total thickness of the package of matched gaskets for the double-row tapered bearing of the drive gear must be increased. And for differential bearings, reduce the thickness of the gaskets on the side of the crankcase, with a circumferential side clearance of 0.64 mm or more, or from the side of the cover - with a circumferential side clearance of less than 0.64 mm.

To repair the rear axle of the UAZ, you need to know exactly how it works, and clearly understand what functions this or that part performs.

See how the rear axle of the UAZ works:

This is a video about replacing bearings in the UAZ rear axle gearbox:

UAZ vehicles cannot be called a very common group of vehicles on modern roads, but despite this, people are often interested in issues related to the design features of the front or rear axle or troubleshooting other units and systems of these machines. Considering this fact, in this article we will consider the device of the front axle of the UAZ using the example of the 3741 model, or, as it is also called, “loaves”.

The old-style front axles, which include part of the UAZ-3741 design, do not differ much from similar new elements of the "Spicer" type. The fundamental differences between them lie only in the design of the crankcase, the dimensions of the constituent parts of the final drive and differential, as well as in some of the parts used.

The main part of the old axle is made up of a split crankcase, which consists of two divided halves, into each of which casings are pressed into with the axle shafts available inside. The covers are also provided for the presence of safety valves, which are responsible for limiting the increase in oil pressure in the system.

The main gear and differential are located in the crankcase, which have a standard device: a drive gear with a small diameter is located in the horizontal direction and is connected to the cardan. It engages with a large driven gear which is positioned longitudinally. A differential is placed inside the driven gear, consisting of four satellites located on two axles and two semi-axle gears.

On the edges of the crankcase there are pivot assemblies, which include ball bearings with housings of the pivots (or pivots) on them. On the side opposite to the axle shaft, the trunnions themselves are attached to the trunnion housings, in which the wheel hub is mounted by means of two bearings. In the housings of the ball joints, there are hinges of equal angular velocities (CV joints), the outer trunnions of which are located in the hubs.

The main feature of the front axles of the UAZ is the presence in them of a mechanism for connecting the wheel hub with the semi-axle, which is made in the form of a clutch, with which it is possible to connect or disconnect the hub and the pivot of the hinge. This is what guarantees the transmission of torque from the differential to the wheel.

When the clutch is disengaged, the wheel hub can rotate freely on the trunnion, which means that the car will have a 4 × 2 wheel arrangement... In the event that the clutch is engaged, the wheel hub through the CV joint will be connected to the semi-axle and differential, and the car becomes all-wheel drive - 4 × 4. The front axles of the old representatives of UAZ, the design features of which are also characteristic of the "loaves", were equipped with hubs with drum brakes installed on them. To control the wheelbase on the bridge there are steering knuckle levers (located at the top of the steering knuckle housings) and steering rods connected to them.

The main faults of the front axle should be attributed the formation of leaks of lubricating fluids, excessive wear of fasteners, defects in bearings, axle shafts, as well as mechanical damage to the beam and wear of components. The reasons for these malfunctions can be very diverse. For example, if a rear-wheel drive car is equipped with front-wheel drive, then driving on uneven road sections will damage the transmission components. The use of winter gear oil in summer or flight fluid in winter can lead to a similar effect, which in any case will not have the best effect on the functioning of the car. Also, remember to maintain constant tire pressure to help prevent bearing and shaft problems.

As for the most common cause of various malfunctions of the front axle of the UAZ 3741, then, in most cases, the reason for their appearance is a violation of the axial clearance of the pivots. To check whether it is broken or not, it is enough to raise the front of the car with a jack and try to swing the wheel up and down. If axial play is observed, then it will be necessary to adjust the clearance of the pivots.

Considering that the UAZ-3741 has a frame structure, then dismantling the front axle will not be particularly difficult. To complete the task, you will need durable and high-quality jack, stops, which can withstand one and a half tons, and a special liquid WD-40, helping to unscrew rusted nuts.

The procedure for removing the front axle is as follows:

Place stops under the rear wheels and make sure that the vehicle is securely fixed.
Disconnect the right and left brake pipes from the rubber hoses to the front brake drums.
Unscrew the nuts securing the brake hoses and dismantle the hoses themselves.
Unscrew the fastening nuts of the lower ends of the shock absorber and the bolts connecting the propeller shaft to the drive gear flange.
Unscrew and unscrew the bipod ball pin nut and disconnect the tie rod from it.
Now it is necessary to unscrew the fasteners (nuts) of the ladder of the front springs and remove the part (ladder) together with gaskets and linings.
At the last stage of work, lift the front of the car by the frame and remove the bridge from under it.

At this point, the removal of the part can be considered complete, and if you decide to repair the front axle, you can proceed with the implementation of your plan.

Domestic off-road conditions cannot scare the owners of UAZ vehicles, but for their proper operation it is necessary to adhere to certain operating rules.

So, for example, UAZ ("loaf") has a front axle, the design of which imposes certain requirements on the control of the machine. Among other things, such axles provide for the disconnection of the wheel hubs and semi-axles, which contributes to an increase in the resource of the axle parts when the front drive is disconnected. Therefore, to turn on the front drive UAZ-3741, you will have to perform two steps: by turning the coupling, connect the wheel hub to the axle shaft, and then, using the lever, turn on the front drive.

In order not to damage the components of the structure, you can turn on the front-wheel drive only after turning on the clutches, both on an idle car and during its movement at a speed of no more than 40 km / h. If the drive engaging lever does not want to take the operating position when the car is off, then you need to start the engine and switch it on the go.

As soon as the machine overcomes the problem section of the road, perform all actions in the reverse order: stop the vehicle, disengage the front axle using the lever and turn the clutch caps to the “4 × 2” position. After that, the car will be able to continue its movement as a normal rear-wheel drive vehicle.

Nevertheless, in the off-season and with constant use of the UAZ-3741 in off-road conditions, the clutches may not be disconnected, it is enough to adhere to a moderate speed mode.

Particularly noteworthy is the transmission oil poured into the axle, the replacement of which should be carried out in a timely manner (according to the manufacturer's recommendations - every 40,000 km of run or more often, depending on the specific operating conditions, the age of the vehicle and the quality of the lubricant filled in). It is also necessary to periodically change the oil in the CV joint, wheel hubs and steering knuckles, and in the drive axles of the "Spicer" type, the guide bushings of the disc brakes are additionally lubricated.

Regular maintenance and proper operation of the front and rear axles of the UAZ-3741 is a guarantee of reliable operation of the vehicle for many years.

Maintenance of the rear axle UAZ-3962, UAZ-3741

Maintenance of the rear axle UAZ-3741, UAZ-3962 consists in maintaining the oil level in the crankcase and its timely replacement, checking the seals, timely detecting and eliminating axial clearances in the gears of the main drive.

Clean the relief valve periodically, tighten all fasteners.

If the oil in the crankcase is heavily contaminated or metal particles are seen in it, flush the crankcase with kerosene before filling with fresh oil.

For flushing, pour 1-1.5 liters of kerosene into the crankcase; raise the wheels, start the engine and let it run for 1-1.5 minutes, then drain the kerosene and fill with fresh oil.

The axial clearance of the driving gear of the main gear of the rear axle reducer of the UAZ-3962, UAZ-3741 is not allowed. Check the clearance by swinging the drive gear by the propeller shaft mounting flange.

If the axial clearance of the driving gear wheel appears during operation of more than 0.05 mm, tighten nut 7 (Fig. 8). Tightening torque - 167-206 Nm (17-21 kg / cm).
