I have completed documenting this work for those interested in the parts, tools and procedure used. You can find my write-ups here.
- 21 BMW R75/6 Remove, Refurbish, Install Clutch
- 11 BMW R75/6 Replace Crankshaft Rear Oil Seal, Oil Pump Cover & O-ring
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.

WOW This is just a fabulous how to do it , step by step overview. I’ve got a 1975 R 75/6 and KNOW that at some point this project is looming in MY future! As always I am so grateful for your precise and informative work that helps all of us keep these old timers on the road! It’s warming up ! wanna go for a scoot??
Dale,
Thank you for the kind words. Of course I’m available when you decide you want to tackle this work.
A ride is always good, except maybe tomorrow morning when it’s snowing 😉
Best.
Brook.
TY and I WILL take you up on that kind offer Already snowing to beat the band up here!
Is there a reason why you chose a refurbished clutch for this replacement? Are Southland’s products better than OEM, or do you simply save money? I ask because I need to replace the clutch and rear main seal in my 74 R75/6. Are you pleased with the refurbished parts?
Hi Tim,
It is less expensive than buying all the clutch parts. Southland does excellent work and I’ve had no regrets or issues with the clutches I had them rebuild.
I hope that helps.
Best.
Brook.
Thank you, Brook, for the prompt reply. Do you send them your old parts, or do they already have the parts that they’ve refurbished?
By the way, your site it very helpful. I’ve worked on my bike a lot over the years, but it helps to see the images along with the descriptions. Thank you.
Best,
Tim
Tim,
They rebuild your parts. Give them a call and they will explain the process and give a date for completion of the work.
Best.
Brook.
Thanks, Brook. I will do that. One last question, probably obvious answer, but you need to purchase a new diaphragm spring, right? I can’t imagine there is anything to refurbish on that.
Tim
Forget my earlier question about the diaphragm spring, Brook. I went on to read more of your description of the removal of the clutch assembly and found that you had addressed that issue there. I should have read that before asking. Thanks again.
Tim
