I was able to loosen the flywheel and push it toward the transmission...transmission removed of course...then with a wrench, I was able to get behind the flywheel and loosen the bolts behind the flywheel.
NOTE: As you loosen the bellhousing, it moves outward hanging on the bolts...makes room enough to keep turning the bolts but when it comes loose, the combination of the flywheel and bellhousing is HEAVY...better have a way to hold it up so it doesnt fall...that could hurt seriously...
I have never tried to put one back in by this method...I was disassembling a motor that was mostly junk but wanted some parts off it. If you can figure a good solid way to support that bellhousing with the flywheel in it in the right location to bolt it back on, then getting the bolts started will be do-able...trying to balance the thing and reach in there to start one, impossible to me...
If you go to the following pages, you will have the military maintenance manual pages on the motor:
