Do I need new Clutch shoes?


One of the clutch shoe clip/washer came off and kind of scratched up the shoe pads. From attached pictures. Do you think I need a new clutch shoes? Is it a good idea to just sand it down and use it again? What do you think is the best thing to do? What would you recommend?

Re: Do I need new Clutch shoes?

If that was my bike, I wouldn't worry about those shoes. I don't see anything to be gained from sanding them. The gouges will disappear with a bit of wear. Good pics, BTW.

What I would be more concerned with is how the clutch drum looks. If that isn't perfectly smooth, it will wear your shoes very quickly. If a clip got caught between the shoe and the drum, it could have damaged it.

I have had limited success resurfacing a clutch bell. I took an M8 bolt of the same thread as the pinion, and fed it through the inside until snug. Then I stuck the end of the bolt into a drill. I used some sandpaper to restore the finish of the drum. Keep in mind that you can only go so far; past 80.5mm and I throw away my clutch drums.

Re: Do I need new Clutch shoes?

Thanks for the help. I really appreciated. When I open the clutch housing there is no clip inside. I only see the washer. I think the washer got caught between the shoes and the drum that's why the shoes are kind of scratched up. I think I am lucky. The clutch drum is till very smooth when touch. See pics.

I have another question. I am having a hard time trying to push the clutch shoe back down. You could see from the pics i posted earlier. Do I need a special tool?

Re: Do I need new Clutch shoes?

You will have to remove the spring to slide the shoe back on. To do this, you will need a set of digital measuring calipers. Measure the spring length, remove the spring by loosening the allan-headed setscrew, then fix the clutch. Clutch setup is absolutely critical; you have to be precise to .05 of a millimeter so that all 3 shoes engage at the same time.

Just to play it safe I would take the clutch off just to make sure the clip isn't hiding in there somewhere.

Thanks for the advice. Which way should I turn to lose the nut that hold the clutch. Is it counterclockwise to lose the nut?

Counterclockwise. You will likely need to use a puller. Definitely DO NOT pry it off, or you will throw the crank off center and cause big time problems.

I have a 5-ton 3-Jaw puller. I think I will use that. Thanks.

Re: Do I need new Clutch shoes?

you need a small harmonic balancer puller with some long metric bolts to get that off with it will save you a headache over trying to use your 3 jaw . iot will also work onthe flywheel

Ooh! Good Idea! I was about to get a 3-jaw puller, but the harmonic balancer puller does make more sense. Thanks SRacer!!
