Final drive spline rehab

2015 July 16

I can’t remember the condition of this final drive when I assembled my 77 R100s back in 2003.  When I had my rear tire replaced recently, I noticed how terrible the splines are. The splines on the wheel are better then the final drive but they will need replacing someday too.

I found this drive with the same ratio and cleaned it up and replaced the spline.  Now it is time to swap the drives.

While it is apart, I am taking the opportunity to pull the tranny back and lube the clutch splines as well.
