View Full Version : Clutch bolts

12-11-2012, 09:44 AM
Has anyone else in the world with a bit of a modified engine had a problem with the clutch pressure plate bolts coming loose??? Second time since my engine build I've had bolts come out of the clutch after power runs but this time it shot into my gearbox and put a nice hole in the housing :(

I had the flywheel bolts back out once. But new bolts from Toyota and use blue locktite. Torque them to spec.

i have never had that issue and i have installed over 100 clutches.

I've always used new pressure plate bolts when doing clutches.

You want to tighten them ALL up without torquing them. Then go back around once theyre ALL snug, loosen, then retorque in a star pattern.

Also I use locktite.

Yeah I've done a lot of clutches too but only ever had the problem on my own car since the power increase

... that's really not a good reason for the bolts to come off... seeing as the dowel pins are what take the load.

Yeah it's got me. Annoying though with this time damaging my gearbox!

What flywheel are you running?

Buy new clutch bolts if these arent holding anymore. I usually replace my clutch bolts when I replace my clutch. Theyre less than a dollar a piece and I dont like taking chances.

Already ordered more. 80c each haha. Running standard flywheel

Weird. I was figuring it was a aluminum flywheel or something that would expand and contract more.
