Re: Stuck flywheel 1960 Merc 35hp

Try the heat and wax technique. I did on a KF7 flywheel that all the usual tricks failed to budge.
Use torch to warm up hub of flywheel and crankshaft… hot enough to melt wax but not so hot as to toast coils. Then touch area with a piece of wax such as a birthday candle.
Wax enters the taper by capillary action. I had the puller in place and under tension
and in a few seconds I could lift the puller and flywheel free of crankshaft.
It worked for me and is worth a try. I was told this is an old steam engine trick.
