Rebuild Questions

I just noticed one of my pistons is scored so I have some work ahead of me. Firstly, do most of you use a piston pin puller or just a socket to get the piston off? If you're using a puller, is it the AC one (part # 0644-328)?

Second, the sled only has 550 miles on it. Is there any worry about only rebuilding the PTO side?

Once I get it appart I'll post a few pics to see if anyone has a diagnosis. Thanks

I've never needed a puller with the AC motors, usually I just pull the circlip and the pin will slide out with finger pressure. The last polaris motor I took apart was a different story.

Usually the pins will just slide out. If it sticks, you can make a puller with a few washers, something for a tube and some threaded rod. I doubt you need to be concerned about changing the other one out. Not much for wear with those few miles on it.

Heat

If the pin doesn't slide easy try a heatgun,

Try to heat the piston, more so than the pin,,,,,,

Just use a socket thats the same size as the pin and tap it out. Its getting replaced anyways.

Thanks for the advice fellas. I was worried I might put to much side-to-side stress on the lower crank bearings, but they came out easier than some of the others I've seen. The side that burned down actually needed quite a bit of force w/ a socket while the other side slide right out with finger pressure.
