Hi All,
I have my 1991 S4 engine hanging on a stand, and I need to remove the crank bolt. Anyone have any advice?

I don't like the idea of using an impact wrench, as I don't want to pound the crank bearings.

Using a flywheel turning tool braced against something immovable is an idea.

I'm not sure any sprocket holding spanners are strong enough.

It would be nice to have something I could bolt to the block with teeth that fit the flywheel. Anything like that--a universal flywheel lock--fit my engine?

I've been shooting PB Blaster on the crank bolt for a while.

Thanks,
Louis

Go to your local home center and buy a piece of 1/4" x 1.5" steel flat bar stock. Use your favorite brand of locking pliers to clamp an appropriate length of the flat bar to the drive plate such that the bar is up tight against both the stand mounting brackets. With it securely clamped you can loosen the crank bolt. Be sure you take care not to tip the entire stand over when breaking the bolt loose.

Thanks Mike. I hadn't thought about clamping. Louis

I always use an air impact wrench to loosen and tighten the crank bolts. I use a 'C' clamp through the flywheel to properly torque the crank bolt.
