Working on my rebuilding the engine on my '69 Trophy 500 project and just pulled the pistons off the rods. Made a press tool to center and align to the wrist pins and pressed them out fairly easily. One was tight in the piston and the other was tight in the rod, both looked like they had seen some hard miles but came out smoothly with a little press motivation! Rods looked really good but one surprise, no wrist pin bushings. I had already purchased replacements and I assumed I would press out the old ones, press in the new and ream to exact size.
Do I need to have them opened up at a proper machine shop have them press bushings in and size to the new pins?
Can I pin-gauge them as they are and if OK go with them as they are with no bushing?
Can I ream them myself to press fit the bushings and size? If so what should the interference be for the bushing fir in the rod?
AND THE BIG QUESTION - When all said and done, what should the small end measure out to to be in spec?!?
Thanks and sorry for all the questions!
