Cannot remove pin from piston Grrrrrrrr By chinascoot (Read 483 times)

So my 157qmj was topping out at 65psi during compression test. I pulled everything apart and found blown piston rings.

I've done a few rebuilds so this WAS gonna be easy enough.

I removed the clips from the piston and the pin is forged into place. I cannot budge it. I tried tapping it lightly with a ratchet extension and a rubber mallet and nothing.

Any ideas scooter brethren? I've hit it with some PB blaster just cause and I'm waiting. This thing had to be under some serious high heat right?

I should note the scoot is a $100 craigslist find.

Try heating up the piston on each end.

Retaining clips came out easy. Will report back with results of both ideas. Thanks dudes.

Allllrighty!!!! Since I did not have a torch I went with the c-clamp/socket method. Worked like a charm. Thanks tvnacman.

Thanks for the response alleyoop, you are always first to respond and that's awesome.
