WTF how did this happen?

Now I need a piston for my 570XP

Need a cylinder? I’ve got a few good used ones... best I could find OEM was 75 on ebay for a piston. Choose to go OEM 575 instead.

@sawgarage have one of these?

I've got a cylinder that I've cleaned up. Has a small line in it that a nail will catch, but it's usable

Yeah, I'm kinda pissed. I didn't plan on needing a hard to find piston. This is a new one on me. Cyl looks good, but I can dang near get a 575 piston and cylinder for the price of a 570 piston

 

[GeorgiaVOL]

Like I said cyl isnt bad at all

 

[Frankavich84]

Was that a chunk of the ring? And yes on the frustration of the price. That’s why I opted for a slightly used 575 top end for $80 on eBay. I’ll throw cabers on it and make it the 575

That's a piece of needle bearing...you better do some more investigating

Nope that's the ring locating pin.

HLSupply has 575 OEM cylinder kits for $156.23, might not be a bad way to go.

I planned on getting it running and selling it, but I might just sell or trade it as it is. I have too many projects. Lol

I'm not to sure that it is the locating pin. There is no port window that would catch the locating pin and drive it up through the piston. How the hell does that even happen? It would be worth digging at the ring gap to see if the locating pin is still there or not. That very well could be a needle out of a wrist pin bearing. Perplexing!

Looks maybe like there's no plating on top of the cylinder and the ring caught the plating and ripped out the pin?

 

[GeorgiaVOL]

It is definitely the locating pin. As to how that happened, it beats me. Weird

 

[concretegrazer]

Didn't the 562's have this problem for a bit?

I wonder if the ring was installed incorrectly upside down causing the ring locating pin to foul. Take a second look at the piston pic the OP posted, the evidence there if the ring is upside down. Maybe they can only be fitted one way due to the location of the pin so they can't be installed wrong but one of the builders or husky guys can verify this.

I dont see how its possible for a ring to be installed upside down.

Can we see the underside of the piston?
