Re: 72 1150 powerhead
sure, I used a piece of steel plumbers strap. I enlarged the holes to accept a 5/16" bolt. Next I bolted it to two of the 5/16" bolts that ring the flywheel nut, and used a block and tackle to lift the powerhead. The end of the B&T was attached to a 1/2" lag bolt in the garage door header. The powerhead is only about 90# or so, but is hard to break loose from the gaskets on the midsection.
BTW- remove the gearcase first. You will want to reinstall the gearcase last, so you do not mess up the crank splines.
