I'm in the process of put a 6.9 into my 86 F350. I needed to change the flywheel to match my 4 speed tranmission. Does anyone know the flywheel bolt and clutch pressure plate bolt torque specifications? I still need to sort out the various electrical connections to make the change (gas to diesel) and haven't had much success finding electrical layout information. Any information will be appreciated.

 

Flywheel torque is 75 to 85 ft lb
Pressure plate is 15 to 20 ft lb. for 10 inch and 20 to 29 for the 11 inch disc.
