Hey guys,
I am installing a new clutch on my car, and was curious what do I torque the bolts to holding the pressure plate on? Also, how do I know if the clutch is centered or not? I used the centering tool, but it has a little slop in it. I tried holding it and eyeing it so hopefully its right.
Also, I got the lightweight flywheel with about 17k on it, should I get the new insert for it before continuing with the clutch project? The flywheel feels really smooth if that makes a difference.
Thanks,
Bill

I dont have the manual handy for torq specs but, with the centering tool just try to center it with your eye as best as you can...
Its also a good idea to get a newfriction plate

The clutch to flywheel tq isn't very much from what I remember. I was thinking 10ft-lbs but check the manual to be sure. Use locktite on them.

Speaking of which, what's the Flywheel to Crank Bolt Torque, and can you reuse the bolts?:goofy:

Aligning it with the centering tool is only to help make it easier to install. Once the transmission is attached the first time you hit the clutch pedal the disc will be aligned perfectly. I also don't have the manual here, but most clutches I've done the pp to flywheel Tq was right around 20-25 lb/ft.
Speaking of which, what's the Flywheel to Crank Bolt Torque, and can you reuse the bolts?:goofy:
60 ft/lbs. Use red (high strength) Loc-Tite. Be sure you have a screwdriver or something jammed into the flywheel teeth to prevent the crankshaft from moving while you torque. If the engine counter-spins (clockwise from the rear), it can easily jump time, which means your engine will turn itself into an aluminum paperweight when you crank it.
Yes, the bolts are completely re-usable.
Also, how do I know if the clutch is centered or not? I used the centering tool, but it has a little slop in it.
I use the alignment tool as a "gross adjustment" tool. I then start one bolt on each side of the pressure plate (3 of the 6 total), and use my fingers to "feel" around the edge of the pressure plate to make sure the clutch disc is equidistant from the edge of the pressure plate on all sides, which means it's centered.
shoult had it right- If it's close, the trans will mate to the engine, and the first press of the clutch pedal will center it the rest of the way as the pressure plate releases the force on the clutch disc.

Thanks for the info Dan. This is exactly what I needed!

If the clutch wasn't centered correctly the input shaft on the transmission wouldn't go into the clutch so your transmission wouldn't bolt together. It doesn't have to be absolutely perfect which is why the tool has so much slop.

Hence my use of my hands to "feel" the clutch disc and center it on the pressure plate. I don't trust sloppy tools- I trust my fingers! :naughty:
Wait- Did that come out wrong? :ugh:
