how to remove a seized wrist pin

[dtr7720]

i took my top end apart only to find trouble, and my right poston, well the wrist pin is seized, and i dont know anybody who has a wrist pin puller, so any ideas in how to get it out?

find a bolt/nut combo that is long enough,use washers the fit inside the piston but hit the wrist pin, use a larger washer to keep some seperation between the wrist pin whole and the bolt end, as you tighten the nut the smaller washer will push the wrist pin out towards the bolt head

i used a socket^^^ but make sure if you put pressure on it that u put something behind the piston so you dont bend the crank rod!!!!

You could use a propane torch and heat the piston up lightly, then try and remove it. You could also put some penetrating oil on the wrist-pin and let it sit over night & try again. If its seized in there, I would replace the top end. If you have to, cut the piston off from around the wristpin. Just make sure you support the rod while you're working on it.

I just used one of these from Lowe's. It was $9. Put a deep socket on the screw side that is smaller than the hole, but bigger than the pin. Then push it all the way through until the pin falls out.
