My Pete rebuild

[Nostalgic]

Of the 6 RX saw cut rods I received, 1 wrist pin bushing measured 2.5032", and another was right on the outside edge of 2.5030". Quickserve lists Min of 2.5020" and Max 2.5030" and my old cores all measured between 2.5025 and 2.5029"

Got 2 replacements, and they match the other new remans range of 2.5023"-2.5025"

If there's any takeaway that would apply to most people reading this, it's make sure to check your Covid-era produced parts, regardless of brand. From batteries to chips to hard parts, it's all pretty much looking like a disaster and crap shoot.

Rod weights varied 48.8 grams, and pistons by 49 grams. I picked up an extra inframe kit and the pistons actually had 2 date codes, one of which matched some of the pistons I already had, but none in the kit weighed the same. Go figure.

I wanted to know how the rods were balanced, and spent the better part of the weekend figuring out how to get consistent, repeatable results haha.



I watched a lot of videos and had to laugh at guys measuring to .05 grams. Some rods would have required me to remove 60 grams of weight if I wanted to make all 6 balanced and equal, and there just isn't that much material to work with. So, short of buying an extra dozen rods to sort through, I weight matched as close as I could get.



I got static weights within 6 grams, reciprocating within 59, and rotating within 40. Seems like a lot, but when grouped on the 3 crank throws, the groups are pretty tight in my opinion.

There's some variance of rotating and reciprocating that may cause some crank oscillation? but I tried to stagger them from hole to hole if it makes sense. Either way, it's a hell of a lot closer than it was. All wrist pins weighed pretty much exactly the same, and I can't see rings or snap rings varying enough to matter, so I left them out of my adventure.
