Installing the wheel drive shaft seal in the rear axle housing without bearing caps
11 - tapered roller bearing; 12 - differential box; 26 - snap ring; 29 - stuffing box; 049a - installation tool; 54 - rear axle housing
Locking nuts of the drive gear of the final drive
a = 8.0 mm
b = 4.0 mm
1. Remove the driveline and drain the oil from the rear axle housing.
2. Remove the rear axle.
3. Determine the initial torque of the gear slowly turning. For this purpose, you can use a cord wound around the flange axis and a spring dynamometer.
4. Block the flange with a rod, securing it with a lever inserted between the spider bolts, and unscrew the slotted nut of the drive gear with a special wrench.
5. Remove the flange from the pinion splines using a puller.
6. Remove the oil seal from the rear axle housing with a screwdriver.
7. Clean the gland seat on the flange. In case of excessive wear of the gland recess, replace the flange.
8. Apply a light coat of grease to the outer and sealing lips of the new oil seal and use a drift to press the oil seal into the crankcase.
9. Lubricate the splines of the drive gear and install the flange, screw on and gradually tighten the new nut so that the gear rotation torque corresponds to the torque measured at the beginning of the replacement. Do not overtighten the nut, but the final tightening torque must be at least 18.0 kgf·m.
10. Lock the nut by caulking its shoulder into the gear cutout.
11. Assemble the knots in reverse order.
