2.9 CLEANING AND CHECKING ALL PARTS

1. Clean all parts of the hub, threaded ratchet, sleeve, spring and end caps. The existing grease
must be completely removed from the hub body and from the threaded ratchet.
2. Check the ratchets for wear.
The wear of the ratchets usually starts at
the outer circumference and shows itself by
strongly flattened edges with uneven wear.
In case of heavy wear, the ratchets must be
changed immediately.
3. Check the freewheel body for damages.
→ Grooves from the cassette are no damages. These are normal signs of usage.

2.10 PRESSING THE BALL BEARING INTO THE THREADED RATCHET

1. Slightly grease the contact surface of the
bearing and the threaded ratchet.
2. Put the threaded ratchet with the toothing
facing downwards onto the mounting /
dismounting tool.
→ Put the ratchet on the side of the tool
with the fitting diameter. The ratchet
may only move minimally in the tool.
3. Put a new ball bearing with the colored side
facing downwards onto the ratchet.
4. Carefully press the bearing into the ratchet with light hammer strokes on the outer ring of the
ball bearing until the bearing protrudes 1 to 2 mm beyond the ratchet.
→ The ball bearing must not be pressed further into the ratchet.
