DC wrist pin

[D Lane]

HI guys I tore my DC apart last week cause i was geting water in the oil found it to be the O-ring in #3 cylinder. I seen the piston was kinda moving side to side in the cylinder like it was sloppy. So when I took the piston out you sould tell where it had been rubing the cylinder wall. The wrist pin in the rod and piston is pretty tight takes a bit of force to move it back and forth. Can i sand on the pin and piston with fine sandpaper untill it frees up or do I need to get a different pin? If so where would I get one? Also two of my rods were in with the numbers faceing the cam and I know thats wrong but does it make the much of a difference? Ive heard other guys on here says theres was backwords too.

Pins are still available, but pricey. Don't think you have anything wrong w/ the pin, but it should be secured in the rod. Don't sand the pin, but lightly sand the piston with some fine paper till it just frees up. Aluminum pistons?
