2. Disconnect the propeller shaft and move it to the 8 side (see Section 4).
3. Using a torque wrench, check the force required to turn the gear.
Record this value for future reference.
Fig. 10.3 Measuring the rotation force of the main gear drive pinion
4. Mark the relative positions of the pinion shaft, nut and flange.
Fig. 10.4 Marking the relative position of the flange fastening parts to the main gear pinion
5. Count the number of threads coming out of the gear nut. Record for future reference.
6. While holding the flange from turning in one way or another, unscrew the flange nut.
7. Remove the nut.
8. Remove the flange using a puller. Do not use levers or hammer blows.
9. Remove the oil seal.
10. Lubricate the sealing lips of the new oil seal with high-melting grease and, using a suitable piece of pipe, carefully tap it into the final drive housing.
Fig. 10.10 Installing the main gear pinion seal
11. Install the flange. If necessary, tighten it with a nut. Do not use a hammer!
12. Apply sealant to the ends of the splines visible in the center of the flange
13. Install the washer (if it is provided) and the nut. Tighten the nut the same number of turns as before dismantling.
14. Measure the rotation force of the drive gear. Tighten the nut until the force is equal to the one specified in the step.
15. To compensate for the resistance of the new seal, increase the tightening force so that the rotational resistance exceeds the old value by 0.5 Nm.
16. Connect the propeller shaft and lower the vehicle.
