The bellhousing pins align the input shaft of the pilot to the crank pit. the bellhousing angle alignment is as important as the differential angle.The oil leak could be rear main seal if bell deflection is twisting the main against the shaft.

From what I've read other people have had similar problems with their zoom clutch.

This only happens when you clutch and the sound is aroun the bellhousing area , is that possible ?

The mistery still continues !
Still shakes like http://www.youtube.com/watch?v=kIwRtHHxp08

Hi there, we still have the problem ,we replaced pressure plate two times
and tried another clutch disc, that's not the problem.

We thought now five possibilities possibilities :

- Pressure plates (pic 1 and 2) incorrect seating ???
- Back side of the flywheel out of shape ? (bottom right picture) a guy told us this possibility but i dont think so at all ....
- Worn Flywheel ( i don't think so )
- Play on the shaft w/t-bearing (not sure if its normal) it has less play on the back side of it (video below)
- Play on linkage making the cluch apply with more power on a side (video)

Here is the new video : http://www.youtube.com/watch?v=G0HhHrKoPjs



thanks !

I did solve my clutch chatter, and it turned out to be a bad slave cylinder.

Yes, at first it didn't make sense. Usually, a leaking slave will just cause clutch fade and you have to pump it to get it to work.

Best I can think, is the leaking Slave Cylinder allowed air into the hydraulic system, and the air acts like a spring, amplifying small un-noticeable normal chatter into a big issue.

Swapped the slave cylinder, bled the system, and all is now well.

Not sure if any of my experience applies to you, but thought I'd tell you what I found.

PS: Another issue is watch where your clutch fork ends up. Sometimes they can catch on the tunnel or other parts as they don't always move exactly where you think they will. This can occur during high torque, like when being in 1st gear, but not so much in higher gears. Fork bounces, and clutch chatters.

u joints out of phase?
Cracked flywheel?
Its not the T10; my suspicion is you might dump almost 3k for a hurst driveline conversion and still have the same problem. Do your research on the TKO and T45s, some people really really dislike them, others love them. Check all your crossmember bolts and engine mounts just to cross things off the list

Looks to me like you have oil or something leaking on your flywheel. It's glazed over and look at the outside edge of it. Looks like oil as been flung off of it, straight lines going from the center out bottom left picture. sure you don't have a rear main seal leak or possibly a freeze plug weeping?
