1975 BMW R75/6: Replace Rear Main Seal, Oil Pump Cover, O-ring, Refurbish Clutch

I have completed documenting this work for those interested in the parts, tools and procedure used.  You can find my write-ups here.

I did the same work on my R75/5 as well which you will find on my site. The main differences between these projects were using Southland Clutch to refurbish the R75/6 clutch where I replaced the clutch on the R75/5 project, and not damaging the rear crankshaft thrust washer this time. 🙂

This is the first time I used Southland Clutch. I am very pleased with their knowledge of airhead clutches, their courteous and prompt service and the quick turn around at a price about one-half the cost of the new parts. I am adding them to my Resources list.
