The differential with automatic locking is shown in the illustration: A - A block of friction discs with a driven gear with a diameter of 185 mm.
Disassembly
Remove roller pin 19 and differential pin 16 with a drift from differential housing 13.
For all illustrations:
13 - Differential case; 14 - Spherical washer; 15 - Satellites; 16 - Differential pin; 17 - Gears for driving drive shafts; 19 - Roller pin; 22 - Friction disc with lining on one side; 23, 23a - Friction discs without pads; 24 - Friction discs with pads on both sides
13 - Differential case; 14 - Spherical washer; 15 - Satellites; 16 - Differential pin; 17 - Gears for driving drive shafts; 19 - Roller pin; 22 - Friction disc with lining on one side; 23, 23a - Friction discs without pads; 24 - Friction discs with pads on both sides
1. Fix the differential housing 13.
2. Remove roller pin 19 and differential pin 16 with a punch from differential housing 13.
3. Install punches 046 in the drive gears of the drive shafts 17.
4. Turn satellites 15 with spherical washers 14 towards the hole and remove them.
5. First, remove the right drive shaft gear 17 (shown in installed position) with friction discs.
6. Remove the left drive shaft drive gear 17 (driven gear side) with friction discs.
Assembly
Mount the friction discs in the correct order on both drive gears of the drive shafts 17.
17 - Drive shaft drive gear; 22 - Friction disc with lining on one side; 23, 23a - Friction discs without pads; 24 - Friction discs with pads on both sides
1. Mount the friction plates in the correct order on both drive gears 17 and thoroughly lubricate the friction plates 22 and 24 with universal hypoid transmission fluid.
2. First install the left drive gear of the drive shaft (driven gear side) with friction discs, then install the right gear of the drive shaft drive 17 with friction discs and install drift 046 paying attention to the fact that friction discs without linings have lugs (arrows).
3. Install pinion gears 15 with spherical washers 14, using drift 046, screw them in until they fit in the differential case.
4. Install the differential pin with a drift into the satellites and spherical washers.
5. Check the friction torque of the differential. It should be 80-160 Nm.
6. Install differential pin 16 and roller pin 19.
7. Remove the differential from the vise.
