How did this happen --- Clutch.

[graphikg]

Ok, for weeks, I have been trying to figure out whats wrong with my car. Vibrations at 1300-2000 rpm, and car will shut off during load at 2k rpm.

I think I found the problem, tell me what you think.

This shouldnt be like this right?




This is not supposed to be like this.

This what it should look like.


Ordered a new clutch (F1 racing stage 3). Think I am just throw in a new SSK kit, and tranny and block seals too.

Broken drive straps are generally caused by poor downshift technique (not rev matching)

Money shifting you mean?

[Danny]

No he means slipping the clutch out without bringing the engine RPMs up manually.

plus better rev matching...

loose crank nut/bolt is a possibility

The stock pressure plate does not take abuse well.

No Way?!? Syncro, can you please explain this... Because I know my crank bolt wasnt to spec when this happened.

i blew my pressure plate 4 times in 2 months, turns out my thrust Main bearings is worn out and there is too much lateral play on the crankshaft. so it would blow every time i bounced revlimter. m50/getrag 240 euro 323t/o bearing.

Any input on how the clutch can react like this by a crank bolt which is not torqued enough.

This is NOT how they're supposed to look.


THIS is how they're supposed to look:




As for what happened to it, my best guess is you happened to it.

i broke a strap on my pressure plate years ago on an upshift at about 7500RPM. Sachs part in my e30 m3, it was under a year and they replaced it under warranty. Looked like yours, was sheared in half

Shift happens.
