Mounting rod dimensions
1. Place wedges under the front wheels, raise the rear of the vehicle and place it on a stand.
2. Remove the rear brake disc. It is also recommended to remove the parking brake pads, although this is not required.
3. Turn away the central bolt of a nave of a back wheel and remove the spacer plug if it is available.
4. Extend the hub wheel drive shaft, move it to the side and secure.
5. Using a small chisel, chisel the castle nut lock on the inner end of the hub.
6. Lock the hub with the pin bolted to it, then loosen the nut with a slotted wrench.
7. Remove washer and gland.
8. Compress the wheel hub with a mandrel or inertial puller, remove the bearing inner race and deformable spacer.
9. Remove the outer oil seal from the hub.
10. Using a soft metal drift, press the outer races of the bearings off the hub housing.
11. Remove the wheel bearing ring using a puller.
12. Rinse the parts with kerosene and dry. Check and replace if necessary. Replace bearing rings and rollers that show excessive wear or spalling. You can not interchange the left and right wheel hubs, because. they have an oil drain thread. R-marked on hub shoulders (right) and L (left).
13. Using a mandrel, press the ring onto the wheel hub. Install the bearing outer races into the hub housing in the same way.
14. Apply some sealant to the seal seat, then press on a new seal with a block of wood.
15. Fill the inner ring and rollers with refractory grease, and also fill the inner cavity of the hub housing between the outer races of the bearings with grease.
16. Install a new deformable spacer onto the wheel hub and insert the flange into the hub housing.
17. Slide the bearing inner race onto the hub and with light strokes on the mandrel press it all the way into the deformable spacer.
18. Apply a little sealant to the seat of the inner oil seal and press in a new oil seal with a mandrel.
19. Install the washer, screw on the castle nut and tighten it by hand.
20. While holding the wheel drive flange, tighten the castle nut until the end play is 0.04-0.06 mm. If the castle nut is overtightened, the deformable spacer must be replaced before further adjustment.
21. Lock the castle nut with a two-point caulk.
22. Install the wheel drive shaft, insert the bolt (and a new spacer, if provided) and tighten it to the specified torque.
23. Install the parking brake pads and brake disc, then lower the vehicle.
