GP Clutch Arm Asssembly

Postby rossclark » Sun Jun 05, 2016 10:50 am

What's the correct sequeuence for the GP clutch arm assembly in the side case?

I can't remember, it's not covered in Sticky's book and I can't find a decent picture that gives a clue.

It has a groove for a circlip at the bottom, but none of the parts diagrams show one. It looks like, from the top it should be -

Circlip
Arm
Circlip
Shim
O ring
Casing
Shim
E clip
Pawl

Can someone confirm?

Cheers Dimitros, I was more wondering, though, if there should be a circlip below the pawl or whether it is just retained by the shaft?

You can fit a circlip,but it is not necessary.
If you fit a a circlip ,the eyes of it can interact with the thrust bush.
Without a circlip,the thrust bush (fitted inside it's house) alone will 'lock' the lever in the correct position.

whats the line up with a LI clutch arm assembly? just building up a chaincase now and don't know if the claw sits at the bottom holding the internal clutch lever on or is the claw on first as it enters the chain case, then the internal clutch lever then the circlip to hold it on? cheers Paul (sorry for the thread hijack)

The parts book shows everything that you need for Li/SX/TV.

Found a pic in an old manual,it has a circlip at the bottom of the GP assembly,
don'y worry if you haven't fitted one,the pawl won't escape.

Thanks again.

Interesting that this diagram doesn't show the 'E' clip at all.
