Differential with automatic locking
A - Block of friction discs with driven gear with diameter of 185 mm
Remove roller pin 19 and differential pin 16 using a punch from differential housing 13.
To all illustrations: 13 - Differential housing; 14 - Spherical washer; 15 - Satellites; 16 - Differential pin; 17 - Drive shaft gears; 19 - Roller pin; 22 - Friction disc with lining on one side; 23, 23a - Friction discs without linings; 24 - Friction discs with linings on both sides
(Material borrowed from an online resource: MercedesMAN.ru)
Secure the friction discs in the correct order on both drive gears of the drive shafts 17.
17 - Drive shaft gear; 22 - Friction disc with lining on one side; 23, 23a - Friction discs without linings; 24 - Friction discs with linings on both sides
The differential with automatic locking is shown in the illustration.
Disassembly
1. Secure the differential housing (13).
2. Remove the roller pin (19) and differential pin (16) using a punch from the differential housing (13).
3. Install the drifts (046) into the drive gears of the drive shafts (17).
4. Turn the 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 gear (17) (from the driven gear side) with friction discs.
Assembly
1. Secure the friction discs in the correct order to both drive shaft gears (17) and thoroughly lubricate the friction discs (22) and (24) with universal hypoid transmission fluid.
2. Install the left drive gear of the drive shaft first (from the driven gear side) with friction discs, then install the right drive gear of the drive shaft (17) with friction discs and install the drift (046), paying attention to the fact that the friction discs without linings have ears (arrows).
3. Install the satellites (15) with spherical washers (14), using a drift (046), screw them in until they are seated in the differential housing.
4. Install the differential pin using a drift into the satellites and spherical washers.
5. Check the differential friction torque. It should be 80-160 Nm.
6. Install the differential pin (16) and roller pin (19).
7. Remove the differential from the vice.
