wrist pin install

I do not recommend doing this by yourself for the first time. It's harder thing you think and requires another set of hands. Yes you can heat the rods or freeze the pins but making a positive stop fixture is a must and you have very limited time to put the pin in before the heat/cold transfers leaving you half way in. I would take it to your machinist and ask to watch then give it a go the next time around. This is just my two cents I'm sure another will chime in.
