Adjust
The installation depth for the threaded ring (1) is determined by the axial play of the through-drive shaft.
1 Tighten threaded ring (1) to 1st stage .
2 Using a rubber hammer, hammer several times on the threaded ring (1) and on the drive shaft (6) 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 threaded ring (1) again to 1st stage .
4 Repeat operation steps 2 and 3 until the threaded ring (1) does not continue turning anymore when tightening to the specified tightening torque of the 1st stage.
When the threaded ring (1) is in this position the through-drive does not have any axial play.

5 Mark position of the threaded ring (1) to the through-drive cover (4) using pen (A).
6 Count off the specified ° on the threaded ring (1) to the right and mark with a pen (B).
Each web and each groove on the threaded ring correspond to a of 10°.

7 Release threaded ring (1) far enough until the marking (B) on the threaded ring (1) lines up with the marking (A) on the through-drive cover (4).
In this threaded ring (1) position the specified axial play on the through-drive is reached.

Lock threaded ring
8 Mount safety washer (2) onto threaded ring (1).
9 Lock safety washer (2) on two cut recesses (5) in through-drive cover (4) by pounding in.
This serves to prevent the threaded ring (1) from turning in operation step 12 when tightening the jam nut.

10 Screw on jam nut (1) up to end stop on threaded ring (2).
When doing so, the threaded ring (2) must not turn, if necessary counterhold threaded ring (2).
11 Position torque wrench (4) such on the claw wrench (3) that they both line up.
12 Tighten jam nut (1) using torque wrench (4) and claw wrench (3) .
When doing so, the threaded ring (2) must not turn, if necessary counterhold threaded ring (2).
