Broken Clutch

[96Formula6spd]

Hey guys I am trying to figure out what broke in my clutch tonight. Its a 91 awd car with a fidanza flywheel and zoom stage 2 that have about 1300 miles on them. Anyways I got in the car so head to school tonight and I start to back up to hear something break. It sounded like a bolt breaking off. As soon as that happened my clutch got a lot of chatter and the car will not idle on its own for more that 10-15 seconds. Then it stalls out like your trying to take off. Checked the master and slave and they both look good and the slave is moving. Any ideas on what let go?

Your clutch fork broken?

Pull your transmission and find out. You may find your problem during removal of the trans (if the bolts spun out), or you will find it when you take it apart. Could be a variety of things from a failed or seperated pressure plate, a delaminated disk friction surface, a sheared clutch disk hub, damaged flywheel, etc.

Yep looks like I get to skip school to fix the car that gets me to school and work. Found the idle issue was cracked hose I think. Going to replace it then move the car. So I can work on it tomorrow. I am thinking one or more of the bolts that hold the pressure plate broke/backed out. Don't see why as I torqued them to 16 ft/lbs and had loctite on them. Times I wish I had a car with a warranty.

Still goes into gear and moves.

well after watching some videos and listening to mine is sounds like the clutch disc broke a spring. At least its still under warranty.

For single disk clutches, I run 20-24 ft/lbs on the pressure plate with 100 ft/lbs loctite Red on flywheel.

For multi-disk clutches (QM / PTT / Exedy), I run 22-24 ft/lbs on the clutch cover and 100 ft/lbs loctite Red on the flywheel.

You can use Loctite Blue threadlocker on the pressure plate/clutch cover bolts if you like.

Thats always a good thing. Mine broke a year after i had it. So i had to buy a new one.

Yeah I used the torque spec in my manual. I always use blue on clutch stuff and have never had an issue.
