I noticed a small quantity of oil leaking from the final drive whenn I loosened the four screws which attach it to the swing arm...i noticed there is an output andd input seal listed on the Motobins website.

can anyome tell me what are these seals, where are they located in the final drive and how to replace them.

I know about the large o ring but was not aware of the other two seals.

any suggestions awill be appreciated.



cheers

If your FD output seal was leaking, you would have oil on your brake disc.
Oil inside the swingarm can come from two places, gearbox output, FD input (or both).

output seal is located in the bell housing behind the disk brake

here is a picture of it removed from the area



be sure you havent overfilled the final drive if you have a leak at the input seal ....also check that there isnt too much play in the pinion ,,,,by that i mean the pinion should not move in and out along its axis (happened to me )
