Planetary seal installation
Replace the planetary seal
The planetary seal should seal the gap between the cover and the side wall. No dust
should reach the chain ring. If the chain ring is dirty, the seal should be replaced.
The planetary seal can be fitted with or without the chain ring in place.
REMOVE THE OLD SEAL
1. Cut the old seal.
2. Remove the entire seal.
3. Remove the old silicone glue com-
pound.
• Use solvent to remove any remaining
debris.
PUT ON NEOPRENE TAPE
4. Fit on a self adhesive neoprene tape
around the planetary unit.
(a) Measure and mark a line 35 mm be-
low the lip of the top plate. Then fit
on the tape with its upper edge along
the line.
5. Have a clean fit with no gaps when re-
turning to the starting point.
PREPARE THE PLANETARY SEAL
6. Roll out some duct tape on a table and
fit on the rubber seal, end to end (ap-
proximately half a seal width from the
tape end).
7. Fold the tape end over and attach it
evenly.
8. Roll on two turns of tape.
9. Fit the rubber seal around the planetary
top plate.
• This may require a small amount of
stretching.
10. Adjust the planetary seal edge under the
lip of the top plate.
FIX THE PLANETARY SEAL
11. Insert a heavy bead of Sikaflex between
the rubber seal and the underlying side
wall.
(b) The bead should be concentrated to
above the neoprene strip.
12. Put on duct tape to secure the seal while
the Sikaflex is curing.
(c) Tidy the tape edge.
