Default How do you remove flywheel?

Hi Guys,

I'm a nitro noob, trying to transplant an engine from some ktm buggy into an 8t. The flywheel from the buggy is too big, so I'm trying to take it off but its very stuck. It looks like a press fit, is there any tricks to taking these things off? Or do I need some tool?

Flywheel sitting across the open jaws of a vise, then tap the crank with a hammer.

Nice one Steve!
Go to an auto parts store, get a "battery terminal puller", best $5 spot you'll ever spend!

You could try spraying some penetrating oil on the crank shaft at the flywheel. Then put the engine on the side of a table with the crank facing upward and the edge of the flywheel on the table. Heat the flywheel with a heatgun. Then tap on the crank shaft with a hammer, but put something in between the crankshaft and hammer like a piece of wood, so you don't damage the crankshaft when you tap on it. Tap just a couple times, then rotate the flywheel and work your way around it.

I normally can get them off by tapping the flywheel from the backside using the plastic end of a large screwdriver. Tap it, turn it a bit, and tap it some more. Usually pops right off.

Those flywheel pullers are one of the most useful tools you can have. It is money well spent if you are gonna stick with this hobby!
