2.8 CHECKING THE SEALING
The sealing must only be dismounted and changed when it is damaged.
1. Check the sealing for damages.
2.
If there is clearly visible damage, replace the sealing:
To replace the sealing, there is a notch in the
hub shell.
3. Using a slotted screwdriver with a blade
width of 2.5 mm, slide under the seal into
the notch in the hub shell.
4. Turn the screwdriver 90° around its
longitudinal axis and push the seal out of its
seat.
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.
