Clutch Center removal

Jonez69 · Wednesday at 1:26 PM

I am not finding any instruction in the workshop manual concerning removal of the clutch center. Mine definitely needs replaced.I removed the circlips and gently tapped about, but nothing really moved. Any help will be appreciated! Thank you!

If you have removed the circlip from the back then it should just tap or press out.

That almost looks like rust , which might explain the issue .
Since the center is trash , I would lay the clutch basket face down with circlip removed, spray penetrant about and tap it out evenly . A heat gun could help if it's really stuck . Good luck .

I'm pretty sure it is residue from the bronze friction plates. I was able to clean it right off. The picture is from a few months ago when I first started working on this bike. I have decided to order a Barnett plate set from CNW along with the new clutch center they offer. I also bought the clutch rod seal as well.

I was able to drive the old center out without any difficulty once I was assured that was the proper procedure. Thanks again!

The bronze friction plates are actually sintered onto a steel host plate. That red residue you see there is fretting.

So, it is indeed a form of rust from the wear? BTW, I truly appreciate having very knowledgable people on this forum. some of you were obviously engineers or machinists.
Me, I'm just a poor dumb country boy in a too small garage who likes to bolt things together!

There is a solution to the too small garage thing. 30 years too late, but hey, BLTN

You did a great job on your footings and walls. I know you are much further along at this point with the roof on,etc.The only problem is that it SNOWS where this is located!

I am jealous of your project

I was about to fit a new Andover clutch centre, when somebody on here posted a picture of the CNW version. I immediately ordered one from Constance at Holland Norton Works and sold on the Andover one. They just look much better made, and are HARD.
