2.4 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. For more information,

please refer to the Ratchet EXP Hub Technical

Manual at www.dtswiss.com. Alternatively, you

can contact a DT Swiss Service Center for the

exchange of the threaded ratchet.

3. Check the internal teeth of the freewheel

body for wear.

If the black surface of the gearing is heavily

worn (no longer black but silver), if there are

burrs or if material has been removed, the

freewheel body must be replaced.
