Cylinder trash, or maybe not?

[Angelr]

I ask opinion to the experts, could be saved by going up and polishing the port of admission? Thanks in advance for your answers

I'm assuming that isn't a single ring piston set up. If not, you can bevel the left to match the right, then round the point off on the inside corners and it'll be fine.

[QUOTE = "Chainsaw Jim, post: 505596, member: 836"] Supongo que no es un pistón de un solo anillo establecido. Si no, puede biselar la izquierda para que coincida con la derecha, luego alrededor del punto en las esquinas interiores y va a estar bien. [ATTACH = full] 88184 [/ ATTACH] [/ QUOTE]
It is a single segment piston. It's from husky 281, I have other cylinders, but I'd like to experiment with this one, to see if it works and how it does it. I'll post photos once I touch it up

 

[Chainsaw Jim]

Now knowing it's a 281 I'll say don't grind on it. Take some fine grit and smooth the edges a bit so the sharpness doesn't scar the piston skirt.

 

[Angelr]

[QUOTE = "Chainsaw Jim, post: 505607, member: 836"] Ahora sabiendo que es un 281 diré que no moler en él. Tome un poco de grano fino y suavice los bordes un poco para que la nitidez no cicatrice la falda del pistón. [/ QUOTE]
Why in a 281 recommends not to grind?

 

[Outback]

The ring ends and locator pin ride in the middle of the intake on that cylinder. Where the damage is. Opening it up might cause a ring to hang at bdc.

 

[Chainsaw Jim]

Exactly what outback said.
A double ring piston usually sends the rings lower into the sharper corners at BDC as shown with the lower line in the picture. A single ring goes down about as far as the line on top.

 

[Redfin]

Do you have the piston that came out of this? That mildly looks like the pin caused that.

 

[Angelr]

[QUOTE = "Redfin, post: 505625, member: 159"] ¿Tienes el pistón que salió de esto? Que suavemente parece que el pin causado eso. [/ QUOTE]
If I have it, I'll put pictures. The segment is broken, but it also broke the bottom wall of the segment socket in the piston, I do not know which circumstance happened first, if it broke the segment when it was hooked and then the wall of the piston or the other way round. Say that the piston wall broke on the side, not on the part of the junction of the segment

 

[Angelr]

I will look if I find a 52mm piston that can adapt to this cylinder, that has the segment stop to one side, maybe oil mac has something similar

Thanks for the link, but I have supplier of pistons barikit and meteor piston

This way for an extra 40 you get a good oem cylinder with it. No brainer.

 

[Chainsaw Jim]

I'm wondering what's up with the bearings after seeing the piston.

 

[huskyboy]

What Jim posted in the link is a no brainer...for 85 bucks I would not be messing around with that chipped cylinder. A decent 181/281/288 is definately worth fixing right.

 

[Angelr]

Creo que esto valdrá la pena, aunque es una medida C y la que estaba tratando de moler era una A, siempre es más fácil tener una buena compresión con una A

 

[Angelr]

I will clean this cylinder and order a metered meteor piston C

 

[Angelr]

Can anyone tell me what times are going well in this cylinder?
