Cleaning And Checking All Parts - DT SWISS Ratchet EXP Maintenance Manual

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.
