flywheel torque

Changing clutch and had the flywheel resurfaced on a 99 7.3. Whats the best way to hold the motor while torquing the flywheel bolts (89ftlb is what ive come up with), or just loctite them and run them in with impact? Thanks

You could bolt a strap across a pressure plate bolt hole to a bell housing bolt hole, but a couple of bolts in the pressure plate holes and a long bar would also do the trick.

Thats a good idea thanks. Anyone by chance know the thread size on pressure plate bolts? Could grab a few longer bolts while at work tonight.

If memory serves me correctly (it has been a few years since I helped do one), they are 5/16"-18 coarse thread.

You can use a fly wheel turning/holding tool,it looks like a pry bar with a bracket attached.

Bill Kay is gaining momentum as a positive member of FTE.
I'm probably not telling you anything you don't already know but that is one heavy transmission. When you go to stab it back in, once the input shaft is through the clutch disc keep the up, down, side to side movement to a minimum. If you let it go to far it will bend your center section of the clutch causing the clutch to be warped and it WILL chatter if you do. I bought a $129 harbor freight trans jack when I did mine and it was one of my more intelligent purchases. With up down, tilt front to back and side to side you can get it perfectly lined up and it is oh so much easier when it is lined up.

Good luck!!
