How much pressure does it take to press the pins out. I'm working of a 1970 302 with stock pistons. I've purchased a set of flat top and wang to set them up better than Ford did. The pins were not all centered, some were some way off center. I can't believe that they moved during the 90,000 miles. I've made a jig like the Ford manual shows and tried using a bridgeport mill HiLo vice but they won't even budge. The manual shows a hydraulic arbor press but what size do I need, a 6 ton, a 20 ton what.
Pressing piston pins out and back in.

If you've got a good set of hot mits (like for smelting) you can throw them in the oven (dont let the wife catch you) and heat em to about 350, sometimes that helps em' "let go"...
The arbor I used is just a 10 ton here at work. (but I heated em in our anealing oven first)
EDIT: now days I just pay the machinist a few bucks more to use floating pins. Plus it frees a hp or two.
