In detail: do-it-yourself repair of a Chevrolet Niva handout from a real master for the site my.housecope.com.

We unscrew the second nut, keeping the shafts from turning with a mounting blade inserted between the bolts.

Remove the nut and washer. Remove the drive shaft flange.

. press the front bearing.

Remove the rear bearing in the same way.

We put marks on the front and rear differential housings so as not to disturb the balance of the unit during assembly.

We remove the rear bearing of the intermediate shaft in the same way as the front bearing of the drive shaft.

To check the technical condition of the transfer case parts, we thoroughly clean and rinse them with kerosene or white spirit.

There should be no cracks on the crankcases and box covers, and wear or damage (chips, dents, etc.) should not be allowed on the surfaces of the bearing bores. Damage to the crankcase and cover mating surfaces can cause shaft misalignment and oil leakage. Minor damage

we fix it with a file; in case of significant damage and wear, we replace the parts with new ones.

Damage is not allowed on the working surfaces, threaded part and shaft splines. There should be no scoring or wear marks on the seating surfaces of the gears. Chipping or excessive wear of the gear teeth is not allowed. Ball and roller bearings should be free from damage on treadmills, cages, rollers or balls, as well as cracks or chips on rings. Radial bearing clearances should not exceed 0.05 mm. The rotation of the bearing rings must be smooth, without jamming. We replace damaged bearings with new ones.

Deformation of forks and sticking of rods in openings of crankcases are not allowed.

We check the absence of traces of jamming on the gearshift clutch hub, as well as on the splines of the differential housing. We clean burrs and scuffs with a file. In case of crushing or destruction of the ends of the clutch teeth, replace the clutch.

We check the condition of the surface of the pinion axle and the holes in the differential housing; in case of minor damage we grind the surface with fine-grained emery paper. We check the condition of the surfaces of the gear journals of the axle drives and their bore holes in the differential cases, as well as the condition of the surfaces of the gear washers and the end surfaces mating with them on the cases and gears of the axle drives.

Before assembling the transfer case, we clean the mating surfaces of the crankcases and covers from the remnants of old gaskets and sealant. We assemble the transfer case in reverse order.

When assembling the center differential, we combine the marks on its housings.

We install the spring washer on the axis of the satellites from the side of the blind hole at the end of the axis.

We press on with pipe sections or tool heads of a suitable size.

.and differential bearings.

In the same way we press on the bearing of the rear axle drive shaft, the rear bearing of the intermediate shaft, the front and rear bearings of the drive shaft. We install the drive and intermediate shafts in the transfer case at the same time.

Apply a thin layer of silicone sealant to all gaskets.

After tightening the nuts of the rear bearings of the drive and intermediate shafts to the prescribed torque (see Appendices, p. 346), we lock the nuts by pressing their collars into the grooves of the shanks of the shafts.

After assembly, fill in oil (see "Changing the oil in the transfer case" p. 32).
