Changing of the drive shaft’s sealing ring

Assembling

Assemble the gear after changing the drive shaft’s sealing ring in reverse order.

Pay special attention to the following during assembling:

•Fill the sealing ring with grease after fitting it on the drive shaft.

•Make sure that only undamaged shim washers with the same total thickness as the originals are put on the drive shaft.

•Press the bearing on the drive shaft and make sure not to damage the bearing’s shim washers.

•When fitting the drive shaft with bearing, shim washers and seal, make sure that the shaft keys correspond with the crown gear’s keys and that the bearing and seal are correctly positioned in the gear housing before the shaft is pressed in completely.

•Put the distance ring on the drive shaft end, and put on the shaft nut. Always use a new nut. Tighten the shaft nut to a torque of 300 Nm and lock it with a punch mark in the middle. The drive shaft nut should be lubricated before it is put on the shaft.

•Change the gasket before fitting the bottom cover. Make sure that it is not damaged. Fit the cover and tighten the bolts to a torque of 26.6 Nm. The bolts should be lubricated before they are fitted. Fill up with oil in accordance with the instructions for replenishing the oil.

Fit the drive gear and tighten the bolts to a torque of 65 Nm.

•Poluzowac 3 sruby mocujace hamulec.

•Turn the lock nuts anti-clockwise and tighten the bolts slightly while checking the gap onthreepoints with a 0.3 mm feeler gauge.

•Tighten the mounting bolts 9,5 Nm and recheck the gap with the feeler gauge.

Tarcza hamulcowa powinna byc wymieniona jezeli calkowita jej grubosc spadnie do 6 mm.

•Disconnect the electrical wires of the brake.

•Loosen and remove the three mounting bolts and remove the brake coil.

•Replace the brake disc on the hub and make a visual inspection of the wear of the friction plate. Replace the friction plate if the surface is worn uneven.
