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.
The higher tightening torque must be used when tightening with a puller directly at the threaded ring.
When tightening with the claw wrench, the torque wrench and the claw wrench must line up, and the torque wrench must be set to the lower tightening torque. The lever effect enables the required (higher) tightening torque to be reached on the threaded ring.
Adjust
1 Tighten threaded ring .
2 Using a rubber hammer, hammer several times on the threaded ring and on the drive shaft or when the through-drive is installed lift the 2nd rear axle on one side and spin the raised wheel several times in both directions so that the input bearing can settle.
3 Tighten the threaded ring again .
4 Repeat steps 2 and 3 until the threaded ring does not continue turning anymore when tightening with the specified tightening torque.
5 Loosen the threaded ring by the specified °.
Each web and each groove on the threaded ring correspond to a of 10°.
