5. Lightly tighten the clamping screws manually and align the clamping set with hub part.
6. Make sure with KTR 250 that the axial back-up ring (component 3) fits the hub evenly.
7. Tighten the clamping screws evenly crosswise step by step to the tightening torque specified in table 1 or 2.
Repeat this process until all clamping screws have reached the tightening torque.

Driving components released or falling down may cause injury to persons or damage on the
machine.
Secure the driving components before disassembly.
1. Untighten and unscrew all clamping screws evenly and one after another.
2. Screw the clamping screws into the pull-off threads of the internal ring (component 2) (see illustration 6).
