How Much Torque Is Enough?
#1
Looking for an impact wrench. Of course the toughest customers on our engines are the front e-shaft bolt and the flywheel nut. How much torque will an impact wrench need to be able to put out to readily and repeatably loosen these guys?

The rear nut is torqued to over 300 ft-lb (from memory, might be a bit off) plus loctite and the ~350 ft-lb unit I rented to get it off last time BARELY did the job. It couldn't budge the front bolt.

290-360ft-lb is the factory setting for the rear nuts. Haven't come across an impact wrench that will budge them other than heavy industry ones with huge 400cfm compressors and 1 inch air lines.
Why bother when you can do it by hand with a large lever socket and the flywheel lock?

argh you would have to tell me that actually when I did my engine I did manage to get it off with an impact eventually, but not after trying the long lever thing (and bending my lever!). But the engine was not supported very well, and the flywheel was "locked" with a prybar (I leave you to imagine the grisly details) so the lever didn't have much chance anyway.
