HA39 fly wheel stuck

[stanley]

The usual hold the motor by the fly wheel and tap the nut method has not worked.I’ve been applying WD overnight and tapping in the morning.No luck.The problem now is I can’t figure out how to use a puller.There are three equally spaced holes in the top,but they are only1/16"in dia,not very deep and not threaded.So what obvious thing am I missing?

Here’s a video by Tubbs about removing a flywheel with a "Knocker" when there
aren’t any holes for a puller.

WD40 isn’t a "Penetrating" oil, it is for water displacement and lubrication.
You need something like Kroil or PB Blaster.
Good Luck.

Using a "knocker" is defiantly recommended, saves abusing the crankshaft threads. However " tapping" usually doesn’t get it done… need more like "wack" and with a heavy hammer. Be sure to be lifting the flywheel, using both hands and having a helper do the wacking is the way to go on a stubborn one.

The knocker and a bigger hammer did the trick.I made the knocker using a couple of castle nuts and a bolt,no welding involved.Thanks again
