Thank you, I am rebuilding a quincy 325 air compressor. I just pressed in the new bushing only to find that the new wrist pin does not fit, after a little research I found that it needs to be reamed, I got an adjustable reamer similar to the one your using, I don't have the tools to measure clearances though, I could probably go slow and be ok but I think I will try and get some of those measuring tools. Thanks again for making this video! I did notice that you were meticulous on measuring at first. Did not see you measure the last rod at all, appeared to be all by feel, maybe I can get away with that too if I go slow with the adjustment and just check pin fit frequently. Also it seems unless you have a pretty good micrometer, that they could do more harm than good, a cheap one could make you think you need to take off more because of inaccurate measurement.
I measured all of them to get close and then adjusted them to fit, the reason it looked like I wasn't measuring the last one is that I had already roughed them all in within a couple thousandths and then fit them to the pins they belong on. Thanks for watching glad to help😁
FYI it's impossible get a true hole with a hand reamer so I found using the hone for the last .001 will true the hole close to round and using a drill will help too to make a straight bore but make sure the reamer is straight in the drill chuck.
@@jonkutsch6171 no in this case the reamer left a really nice finish and in my opinion cross hatching is not necessary on oil injected bushings/bearings, but that's just my opinion I could be wrong. That said the dozer runs great now with no signs of excessive wear or trouble after the 20 hour oil change.
yes. I use a 340 grit 14mm hone. The hone actually makes the bore more true too. I found it almost impossible to make an exact hole using a hand reamer especially if you did it by hand and that's why a drill works best but make sure the reamer spins straight in the chuck of the drill.Take your time on the first one and use it to adjust the reamer with it and if a little tight on the shaft use the hone to get your clearance. FYI the OEM shaft I got was .002 smaller in diameter than the original so the new Genuine rocker was too loose.
@@GRTRanchadventures I found the hand reamer is impossible to leave to true round hole and that's why I use a drill but still it's a little off so honing will true the hole and knock down the high spots.
@@jonkutsch6171 be careful, you cannot hone a hole straight, just because it measures good all the way through the hole could be banana shaped. A reamer will produce a straighter hole but not perfect, the best result would be from boring the holee in a lathe or milling machine. Moral is, don't rely on inaccurate tools for precision surfaces. I know the adjustable reamer is not perfect but it is still orders of magnitude more accurate than a hone.

cool. thanks
I use a rechargeable drill with the reamer and ream to the OD of the pin and hone the clearance to .001.
The pistons are longer than I expected.
Did you hone the bushes after reaming?

@@GRTRanchadventures correct. The hone helps with crosshatch and can remove .0005-.001 for final fitting.
