I got a flywheel for my 51 that does'nt have starter pawls on it. How do I get then off the old flywheel?

Why would starter pawls matter? I have never used them with bolt method to remove, is this what you do?

Loosen flywheel nut and put a punch in center of crank and give a whack. Most come off.

Also leave nut on covering the threads with nut half off and whack the nut. (WARNING I fubared the ends of threads ONCE like this still was usable though)

I have a 3 jaw mini puller that fits under flywheel even though they are super tight on back side.

Super stubborn ones I have learned to spray PB Blaster and let soak in around flywheel.

All I can think of for now.

There is some cheap cost husqvarna flywheel tools listed in this thread. I still need to pick both of them up just to have on hand.

Here is the husqvarna knocker tool for the 51 and others with fine threads. http://www.ebay.com/itm/PART-TOOL-FLYWHEEL-REMOVAL-FINE-THREAD-HUSQVARNA-/390023778896?pt=LH_DefaultDomain_0&hash=item5acf3a9250

Here is the one for coarse threads. Which saws use the coarse threads? 346 372 etc?

Quick pic I borrowed. Looks like they may push out from back side of flywheel? Anyone know for sure?

Thats what it looks like to me. I tried tapping them out with a hammer and punch to no avail. I thought about heating the flywheel but havent tried it yet. The keyway is gone out of the flywheel so its no good to me.

You can use flywheel without the key way. Just line up and tighten down. My 3120, 372 and another I cant think of used no keyway. just slid on and tightened to re-time.

People grind the molded keyways out of flywheels all the time.
