What the hell. 2 hours to remove the flywheel

[TIM LUTZ]

I spent 2 hours last night removing my flywheel. 1 minutes with the impact, 4 minutes waiting on the compressor. 2 minutes with the impact, 4 minutes waiting on the compressor. Got out the hammer and gave er a couple whacks. The crank is junk anyway so I gave er a few more. Got the propane torch out and heated it up to 250 degrees. Ran out of propane. Went to Walmart got some propane. Heated it to 450 degrees and hit it with impact for 2 minutes and it popped. I had only slight rust stains on the taper surface and the Vito's 4 degree key looked fine. Only question is are the damn lights going to work now. You know what heat does to magnets.

Wacking it with a hammer is not good and will throw the magnets out.

the magnets are glued in, shake the flywheel by your ear, if you hear clicking or anything the flywheel is bad, which i would expect from being hit wit ha hammer and the torch

Put it back together. If you can't get a spark then its no good. Pretty quick and easy to change if you have a good one handy if that one is bad.

shake it, as mentioned, run some emery cloth in the taper to clean it up. get a screwdriver and drag it over the inside of the flywheel. it should grab to 12 evenly spaced spots. the magnets are not verry strong to begin with, but they are permanent magnets, none the less, so idk if 450 degrees is enough to hurt them, but may be enough to loosen the glue.

Hope you all don't think I hit the flywheel itself with a hammer. I just gave the center screw on the puller a couple shots.

Magnets still seem strong, nothing sounds loose. That must be some glue them jap's use. I don't know of any adheasive that can take that much heat. I know I got the center section that hot cause I had the laser IR on it the whole time. I can see a little of the glue on the inside and picked around at it with a scribe and it seems solid.

I just dont see how it won't come off with the puller.....you have it in all the way?

That's just it. I've never had one come off that hard on any bike. Not rusted at all just a little stained.

The only time I've had them be this nasty is if the threads on the flywheel were questionable.

In those instances...you just weld a puller on and remove it.

Sure you trashed a flywheel and puller, but you gotta ride, right? LOL.

[papa_smurf49319]

they can be a pain in the arse if you bike has a nasty habit of welding the crank to the flywheel! Ask me how i know!
