Barn find trailfire 440 problems #2

[Cole4430]

I would like tips for getting an 80 trailfire unstuck. I have the crank split and the heads off the mag side piston is free but the clutch side is seized. I would soak it with oil but it’s stuck at the ports so all the oils you put runs out. Tried tapping with wood block and hammer but not very long or with much force. Other that that piston engine looks new. Will take any help or advice. Thanks

I ran into the same problem on my 440. I tore it all down, only for mine both pistons were seized from sitting. Make sure you have the bottom of the case apart so you do not wreck the bearings by putting undo force on them. I used a big brass drift (punch) and brass hammer to beat the things out of there. I was planning to put new pistons, rings etc. in anyways so I wasn't concerned about the pistons condition, as long as I got them out. They came out, did not score the walls of the cylinder at all. Just be sure not to knick the sides of the cylinder with the brass drift because it will leave a mark. I made that mistake and it left a small mark, but it runs so I'm not too concerned for what I do with the machine.

A normal hammer would do if you only have the budget for the drift, but the punch being brass is the key because it delivers the blow from the hammer well. Sometimes those things are just stuck in there and you have to do what you need to do to get them out and take a chance.

Let me know if that works or not. Up to you to try it, know the risk you take by hammering on things lol.
