how do I tighten the crank bolt??

[dpuma8]

I have an L28 on a pallet in the garage. I am trying to take off the flywheel to make room for the new Fidanza wheel.The problem I am having is the crankbolt is loose so I need to deal with that as well now.

 

So how can I get my crank bolt on tight AND get my old flywheel off?

Impact gun for rear fly wheel bolts, and I waited till the motor was in the car to torque the crank pulley bolt using the transmission in fifth gear as a stop (wheels chocked). 

 

The alternative/correct method for off the car rebuild would be a flywheel locking block.

You can get a flywheel holding tool that holds on to the ring gear teeth. This will allow you to hold the flywheel to torque the bolts.

Beerman is correct, you can make one out of some strap steel or angle iron as well. 

 

If you have the flywheel off, a 4' piece of 1 1/2" or 2" x 0.250" angle iron should be MORE than enough to punch a couple holes in there and use flywheel bolts to lock the crank from turning while you torque the front bolt.

 

Remember to use the THICK HARD washer for the front, and to LOCTITE BLUE the threads at least. If you use that thin stock washer, and not the later KA24 one (with matching longer bolt) chances are good the washer will deform at torque, embed, lose torque, and come loose even with Loctite Applied. Loctite Green Cylindrical Parts Locker/Bearing Mount on the crank snout will hold the pulley nicely in place as well.

 

Do it right the first time, and it will stay on there. Using a propane or MAPP Gas torch on the head of the bolt will heat everything enough to release it later. I've actually Loctite Red'd the crank bolt and have not had an issue removing it later.

 

Good Luck.
