shaft replacement
OK lets see if I can remember how we did mine on Saturday.
- remove rear wheel
- remove battery earth wire from Gbox, remove battery box.
- mine has a Y piece but if you have collector box that probably has to
come off
- disconnect paralever, remove shock
- remove gaiter clips and pull back front gaiter from gbox
- undo 4 front u/j bolts from gbox output
- undo bevel drive / paralever bearings - 2 different size allen keys
on mine the inner one needed heat before it would move
- remove bevel and stick its tapered bearings in with grease to
stop them falling out
- remove swing arm bearings, remove swing arm, remove shaft
Reassembly
- the front gaiter is a bastard to get on - we soaked mine in boiling water to
make life easier. Attach it to the swing arm and replace clip
- put shaft in swingarm, position swingarm and tie its back end to frame
to keep it horizontal
- mate up shaft to gbox output, replace 4 NEW bolts and tighten extremely
tight with aid of rubber mallet
- now you have to replace the front of the dear little gaiter on the back
of the gearbox. Rob made a small hook from a coat hangar, this is a PITA.
- replace swing arm bearings dont tighten yet
- lube the spline in the rear uj with special lube (normally white but Sherlocks
gave me blue) and position it facing back horizontally
- fit the rear gaiter to the bevel box and push the bevel box into the
swingarm so the splines match up - you may not get this at first attempt
- refit bevel box bearings, fit gaiter to swingarm
- centralise swing arm by adjusting both bearing pivots
- refit paralever and shock
- torque up everything according to the manual
- replace everything else
Think thats all
Cheers
