8

Adjust axial play of through-drive

The installation depth of the threaded ring determines the axial play of the through-drive shaft. It therefore has to be ensured that the threaded ring is tightened to the corresponding tightening torque depending on the special tool used.

AR35.30-W-0476-01A

The higher tightening torque must be used when tightening with a puller directly at the threaded ring.

If the claw wrench is used the ring must be tightened with the lower tightening torque. The higher tightening torque is achieved at the threaded ring due to the lever effect of the claw wrench.
