Install side gears with thrust washers by turning them in the differential case.
Install new circlips on pinion shaft.
Heat the new speedometer drive gear to a temperature of 80°C and install it on the differential box so that the gear protrusions fit into the grooves of the differential box. To facilitate the installation of the gear, use the tool KM 459.
Lubricate the teeth of the speedometer drive gear with bearing grease.
Heat the differential driven gear to a temperature of 80°C, controlling the heating temperature with a thermochromic pencil, press it onto the differential box and secure with new bolts.
Press the tapered roller bearing inner races onto the differential case.
Press the outer races of the tapered roller bearings into the gearbox housing.
Install the oil seals, filling the space between the sealing lips with protective grease type 1948 814/90 001 804.
Install the differential case to the gearbox housing.
Apply protective lubricant to the threads of the adjusting nut. Install the sealing ring and tighten the adjusting nut with KM 447.
When reusing the parts, tighten the adjusting nut to align the marks made during disassembly and obtain a moment of resistance to turning the bearings within 6-10 kgf·m. When installing new bearings, the moment of resistance to rotation should be in the range of 17-19 kgf·m at a rotation speed of 1 rev / s. After installing the gearbox housing and differential, provide a moment of resistance to turning the bearings in the range of 17-19 kgf·m for new k and 8 kgf·m for run-in bearings.
Lock the adjusting nut by bending the tabs on the lock plate.
Install plugs in the adjusting nut and in the gearbox housing.
Apply bearing grease to the differential cover gasket, grease it to the cover, install the differential cover and secure it with new bolts.
Note. Assemble the differential with the following in mind:
- before assembly, lubricate with oil intended for highly loaded parts, the axis of the satellites, satellites, thrust washers;
- Replace the driven and driving gears of the final drive at the same time. When installing new gears, pay attention to the identity of the markings in the form of annular grooves at the tops of the teeth;
- install the seals flush, with the working edge outward.
