2. Disconnect the cardan shaft, move aside and secure.
3. If the semi-axle is of a semi-floating type, then use a torque wrench to check the moment of resistance to turning the final drive shaft (see photo).
4. Mark the relative orientation of the final drive pinion shaft and propeller shaft flange nut (see photo).
5. Determine the number of threads between the end of the nut and the end of the pinion shaft.
6. Secure the flange against rotation and loosen the nut (see photo).
7. Loosen the shaft nut.
8. Remove the flange. Use a puller if necessary.
9 Remove the gland.
10. Press in a new oil seal with a mandrel, lubricating its working edge with refractory grease. The stuffing box should go into the socket without distortions, to the full depth (see photo).
11. Install the flange in place, matching the marks made before disassembly. Tighten the nut if necessary to bring the flange into place.
12. Apply non-drying sealant to the ends of the splines visible in the center hole of the flange.
13. Install washer (if provided) and tighten the nut. Tighten the nut by counting the number of threads determined prior to disassembly.
14. If a semi-floating type semi-axle is installed, then gradually tighten the nut, measuring the moment of resistance to turning the main gear. To compensate for friction from the new stuffing box, tighten the nut to a slightly higher torque than specified prior to disassembly, but no more than 0.48 Nm.
15. Establish a semiaxle and lower the car.
