576 xp cylinder part numbers (3)

[usmcbuckwild]

I am working on a 2015 manufacture date 576 xp total top end failure. Appears the top ring locating pin came loose, moved around and resulted in broken ring and all sorts of damage to the cylinder (its WRECKED)



Got a couple used cylinders (thanks @Onan18 ) to try to bring this back to life on the cheap. Ordered an aftermarket piston (Golf) which I’m not real happy with. Was looking at cylinders for Cyber Monday deals and came across 3 different part numbers for the 576xp cyl:

575257406
575257404
575257402

So i went out in the garage to check out the cylinders I have on hand. I have 2 different numbers on the cylinders but can’t find ANY apparent differences in them.



Cylinder that came off the 2015 saw:


Does anyone have any intel on the 3 part numbers? Is one more desirable than the others?

It makes me wonder if there are differences in port timing between them.

Idk about the 576 but I bought an OEM 575 for $110 on cyber Monday.

This happened on the first tank on a 576 last winter on me.
