Input shaft seal
Note. When installing, you will need a new retaining cap for the flange nut.
1. Drain the oil from the final drive (see paragraph 10).
2. Remove final drive assembly (see paragraph 2) and clamp the knot in a vise.
3. Remove the lock cap and mark the relative position of the nut, flange and input shaft of the final drive (pic. 3.3). Discard the cap as you will need a new one during installation.
4. Screw a steel strip to the flange to secure the flange from turning. Loosen the flange nut, counting the number of turns to remove the nut.
5. Using a suitable puller, remove the flange from the shaft, then remove the boot. If the boot shows signs of wear, replace it.
6. Pick up the cuff of the input shaft with a screwdriver. Clean the seating surface under the cuff.
7. Lubricate the lip of the new seal, then press it flush with the outside of the housing. For pressing, use a piece of pipe of a suitable diameter.
8. Put on the boot, then install the flange, aligning the marks made before removing it. Screw the nut on the number of turns counted earlier and align the marks on the nut and flange.
Attention! Do not overtighten the flange nut. If you overtighten the nut, the spacer located behind the flange may be deformed. In this case, the washer will have to be replaced. This will require disassembly of the main transmission (see paragraph 1).
9. Secure the nut with a new lock cap.
10. Reinstall final drive (see paragraph 2), then pour the oil into it (see paragraph 10).
Cuffs of output shafts
Note. When installing, you will need new bolts for fastening the drive shafts to the final drive flanges, as well as spring rings for fastening the final drive flanges.
11. Drain the oil from the final drive (see paragraph 10).
12. Turn out bolts of fastening of a leading shaft to a flange of the main transfer. Secure the end of the drive shaft with wire. Note. Do not allow the input shaft to hang under its own weight as this will damage the constant velocity joint.
13. Using a suitable lever, remove the flange from the final drive. Be careful. so as not to damage the boot or the final drive housing (pic. 3.13). Remove the flange, then remove the boot. If the boot shows signs of wear, replace it.
14. Gently remove the cuff from the final drive housing. Clean the seating surface under the cuff.
15. Remove the flange circlip from the splined shaft (pic. 3.15).
16. Install a new retaining ring. Make sure the ring fits into the shaft groove.
17. Apply a little oil to the edge of the new cuff and press it into the final drive housing until it stops. If necessary, use a piece of pipe of a suitable diameter (pic. 3.17).
18. Put on the boot, then insert the flange. Make sure the flange circlip is in place.
19. Align the drive shaft with the main gear flange, insert new flange mounting bolts and tighten them to the required torque.
20. Fill oil into final drive (see paragraph 10).
