I am having a hell of a time trying to get the cylinder over the piston. Is there an easy way of doing this? Also, do I have to change the pin that goes into the piston or can I use the old one? Thanks!

attach the piston to the end of the rod with the new pin and don't forget the clips, easiest way i found is to lube it all up with some oil, align the rings to the pins and hold them in the grooves with your fingers, and slip the cylinder over it.you may want to practice with just the piston and cylinder before you attach the piston to the con rod. some find it easier to pop the top of the piston in leaving enough of it out to be able to slip in the wrist pin.
