22. Fit new slide ring seals on the hub and on the brake housing cove, as follows:
NOTE!
Handling and fitting the slide ring seal should be done with great care. All parts which belong to the slide ring seal
should be clean and free from impurities and oil.There is the risk otherwise that the rings might end up askew
resulting in a leak. Also, do not use a rag which leaves fluff.
The lapped sealing surfaces must not be damaged or scored.
Make a support ring by joining the ends of a plastic hose, O.D. = approx. 6 mm (0.236 in) L = 805 mm (31.69 in).
Put a piece of tape on the support ring (plastic hose ring) so that it forms a tab.
23. Position the support ring and O-ring on the slide ring. The support ring should be positioned between the O-ring
and slide ring flange, see
.
