Changed out my rear tire yesterday and the way I do it I pull the final drive out.
I noticed I had some dried up seepage of final drive fluid at the driveshaft housing mating surface. Did a search and found there is an oring in the driveshaft housing that fails. Well my search in the microfiche showed the oring but brought up another question.
The microfiche shows a shim between the final drive and the driveshaft housing and lists numerous thicknesses from T=.15 to T=1.0. I'm assuming that T is thickness in mm, which is @ a .035" range.
I do not have a shim there and because the driveshaft housing and the final drive combined length make up the left side swing arm length I'm thinking the shim thickness is selected at the factory to make the swing arm lengths equal.
The rear axle comes out before loosening final drive but mounting final drive to wheel first with putting rear axle into final drive and left side of wheel then mount final drive to driveshaft housing loosely then finish axle assembly the tighten the final drive.
Has anyone looked into this and have a method for determining the right shim thickness? OR am I overthinking this up to 1mm possible change in left swingarm length?
If anyone has insight on replacing the oring that allows the leakage from between the final drive and driveshaft housing please post.
