Default I made a big mistake! (your gonna love this)

So i am breaking down my engine. I was impatient at the moment with my wife yelling at me to go to the store. well i am trying to get the flywheel off and i am taping and taping the back of it (like i always do to get it off), and it wouldn't come off. Meanwhile my wife is nagging and nagging. So i said screw it and to out my 4oz ball ping hammer and started tapping on the end of my crank shaft.

It finally came off. So later i am putting it back together and the flywheel will not go on, and i couldn't figure out why. Well the tip of the crank mushroomed a itty bit. So i filed the end a little and it went back on. If the crank bent any i could not tell. It was smooth with the bearings and when i run it the clutch and spur are fine.

So basically from what i can tell everything is fine. But would like you guys input on this. Did i ruin my crank?

This is embarrassing

hmmm how hard did you hit the crank on the end when the flywheel did come free is my concern... would do more damage putting that stress on the crank pin and con rod ( and piston sitting in the sleeve ) than on the end up the crank itself, if you only burred the end up and now everything goes on ok it should be ok but i would be concerned about damaging the internals of the engine more....

I took the P/S and rod out. SO it was just the crank i was taping on.

I do some dumb stuff, but not that dumb

pep boys or kragen,what ever you have out there sell windshield wiper pullers for $8. Stop by on your way home,just use a bolt in the end of the crank when using it or rigging like you just did(stops the mushrooming).

Heat the flywheel with a heat gun next time.

Get it nice and hot.

As the aluminum (or steel) flywheel cools; there will be a release point where it will just 'let go' from the collet real easily without having to beat it into oblivion.

Thats nothing. I know someone who couldnt get the flywheel off. He was using a flywheel puller too. When in doubt, use brute force, so he did and it did come off. Unfortunately so did the crank, since he had forgotten to actually take the flywheel nut off ! :-D

And no it wasnt me!

I remember the days(long time ago) when I was naive and used to tap the crank just like that to get the flywheel off when it was really stuck. I mushroomed a couple cranks myself(RTR engines though) and had to get filing. It should be fine as long as everything goes on and off smoothly, but I would HIGHLY recommend a flywheel puller for the future.
