'48?? or 49 8BA torque ft.lbs for flywheel to crank shaft
Anyone know the correct ft.lbs torque to tighten my flywheel to my crankshaft?
Van pelt seems to indicate 75-80 ft. Lbs.
My crank shaft starts spinning tightening my flywheel at around 35-40??
Can they be right? Should I brace tight my flywheel for this amount of torque?
Again..would appreciate some help. Broke a clutch pressure plate cap bolt yesterday at 17-20. Don't want to have to go thru that mess again..BTW..I got that broken bolt out with a left screw drill bit with my drill in reverse..thought it was going to get ugly but I did catch a break.
I'm holding off until I get some of your thoughts.
Thanks

I'd stick to the 75 end of that, yes it's correct. The way I kept my flywheel from turning was to make a locking device out of angle iron. Very simple and worked for removing too. See picture. You want the angle iron to hit the ring gear at a 45 deg angle, and you want to use one of the holes near the top of the block that have plenty of meat around them. You flip it over from what is shown for tightening the bolts. You can use it when tightening the PP bolts too.

Do you have a set of thread chasers? I would buy a set, they're cheap. Clean the flywheel threads, use quality bolts, and a good torque wrench with the factory specs.
Chasers won't cut like a tap, and make the fit loose. They only clean out the existing threads. You can make your own by cutting longitudinal grooves in an old bolt. Good idea to use them on any old, rusty, dirty threads.
