My husband removed a T5 and hydraulic clutch from a 1985 Camaro 2.8L and is rebuilding the clutch. The clutch disk bolts are 8mm and another forum said they should be torqued to 50 #'s. They break at around 30#'s so he purchased new ones, and likewise. We do not have a manual for this application, and do not wish to buy one just for this one time. He checked a couple other manf. manuals and for lightweight v6 it was only 20#'s or so. Can you please give us the recommended torquing for this application?

Suggested Repair

Torque the pressure plate bolts to 20-25 ft-lbs by bolt size: 20 ft-lbs for 5/16-inch bolts and 25 ft-lbs for 3/8-inch bolts. Do not use the 50 ft-lb figure, which applies to flywheel bolts (typically 50-65 ft-lbs) and can break the smaller pressure plate bolts.

Conversation Summary

The owner asked for the correct torque for the 8mm clutch/pressure plate bolts on a 1985 Camaro 2.8L after bolts broke around 30 ft-lbs when following a 50 ft-lb figure from another forum. The expert said pressure plate bolts should be 20-25 ft-lbs (20 on 5/16-inch bolts, 25 on 3/8-inch bolts), while flywheel torque specs vary from 50-65 ft-lbs.
