T56 fastener torque specs

I last did this a few years ago, cant remember what the specs are and I cant find the sheet I wrote it on. I probably put it aside somewhere where I wouldn't lose it. I only have an 82-92 shop manual, if I need to I will go buy a 4th gen one, but I was hoping someone else had one handy.

Anyone know how tight I need the flywheel and pressure plate bolts?

And isnt there some place on the the pressure plate or clutch fork where I need to apply some grease?

Re: T56 fastener torque specs

Torque goes with fastener size.

Flywheel bolts should be in the 60-70 ft-lbs range, clutch bolts around 35.

Put grease wherever moving parts rub against each other... a SMALL amount (emphasis on SMALL) on the clutch splines, some on the throwout groove, some on the clutch fork pivot, plenty in the pilot.

Re: T56 fastener torque specs

Depends on which T56.

If it's an LT1 T56 "pull" pressure plate, those are 22 or 25lb-ft which isn't typical for 3/8 coarse thread.

Any other "push" clutch, you can google based on the thread size.

You can put a tiny amount of grease at the disc hub - to - input shaft area. Don't over-do it.

Any fork pivot location is good to grease. Lightly coat the throwout bearing tube also. Don't put enough that it might get flung into the clutch.
