what kind of clutch do i have?

yamaharider324 · Aug 19, 2008

*UPDATE AT THE BOTTOM OF PAGE POST #17*

So I bought this bottom end for 10 bucks about a month or so ago and haven't really worked on it. I can't get the clutch nut off no matter what I try!

Is there anyway to get that thing off without a clutch nut tool?

Also, what brand is the manual clutch it came with? I think its a TB but am not completely sure. Some pics:

clutch parts and my sorry attempt at making a clutch nut tool:

Any help is much appreciated!

either the correct tool with air impact or a good chissel and hammer will get that f er off

What motor? Might be the one that comes on China 90/110???

It's a manual clutch of some sort. If it's TB it will have TB written on it.

could be a tb like Dougtrip said..could also be the ahp but IMO its prolly a chinese....

Its a honda bottom end and the guy that I got it from told me I had a 88 kit on it before it was stripped down.

Get the clutch nut tool! If you're into building engines, it will be invaluable to you. You'll need it anyway in order to get the nut back on to the correct torque. Also, get a strap wrench to keep the clutch basket from rotating.

You can always improvise, but with it comes the risk of doing more damage to the motor.

I guess I will be ordering a clutch nut tool when I build the engine up so i do it properly.

I checked out the brand x clutch on ebay and it does look pretty much the same.

Also, today I noticed there are some engraved or marks punched into the clutch hub or basket. Same spot as a fews posts above where the TB marks are.

arlindsay1992 · Aug 20, 2008

What do the marks say?

yamaharider324 · Aug 20, 2008

Either "L5040" or "L504J"

The last mark is pretty hard to tell. Its either a really messy "J" or a "0"

arlindsay1992 · Aug 20, 2008

Well, maybe somebody can check with their clutch for similar markings and let you know what you have. Why does it matter what kind of clutch you have anyway? If it works run it. If it breaks replace it.

I'd just like to know in case I needed new clutch plates or parts for it.

Thanks for all the help everyone.

arlindsay1992 · Aug 20, 2008

Honda TB sells plates that will fit. The only other part you might ever need for your clutch is springs. All the springs for those manual clutches are the same and you can get them from DrATV.

Ok thank you arlindsay!

*UPDATE*

I think I have a china bottom end. For one, the cases are painted and my stock 00 xr50 cases are not.

The top (and bottom) two studs center to center measure: 52mm

The studs diagonal center to center measure: 68mm

The "opening" where the cases meet measures: 56mm

The small end of the crank where the wrist pin goes measures: 12mm
