Piston contest.

[Vman]

a 350 or 353?

 

[HiOctane]

From a 257.

 

[Mange]

No correct so far, but 254 is closest.
I go to bed now. I post answer in the morning.

 

[bugfart]

Only one ring...
So I'm thinking Husky blower...

 

[Vman]

261

 

[spacemule]

55 Rancher. Just a wild guess.

 

[bugfart]

I'm having trouble figuring out how big it is. Can you set that next to a gucci shoe-tree or a baby's arm holding an apple?

 

[Simonizer]

Wrist pin bearing failure from a 266 Husq? Don't really recall that piston?

 

[HiOctane]

Wrist pin bearing failure from a 55 rancher Husq?

55 has closed side piston.

 

[Mange]

154!
254 is a bit different, but same size.

HiOctane was very close, I say he wins this part of the oiston contest.

I didnt remember the part # was different from 154 to 254.

It has different size of the pisons ports on the sides.
XP is not the same at all, it has a port all the way down, so there is no sides on it so to speak, just front and back.

I can not explain better... If you like I can post pic's.

 

[Mange]

I don't know if it is different numbers, or just different design or something...

Come on Mange put us out of our misery.
What broke the piston ??

Mc Bob.

 

[MacDaddy]

Mange its a 154 husky Also the pin that holds the ring from spinning came out and the ring spun over to the tranfer port and cought a edge and broke the piston Sorry it took so long I have been BANNED for a while

 

[Mange]

Yes, the piston pin needle bearing was worn bad enugh to release the needles out in the engin, but crank and cylinger is surpricingly still good, or at least good enugh, I changed the piston and it runs very well.
I thought I would get out small pieaces, if I got any out at all, but I counted the needles missind and the ones I found, so one is unaccounted for, I guess it is in the muffler or dust.

 

[ross_scott]

is this piston from a 365 model?


Mechanic says to customer: Piston broke
Drunk walks past and says: yeah I know just how you feel

 

[Mange]

Nope it is a 154 piston.
HiOctane was very close so I consider him the winner of the model part.
PWB guessed correct on what happened.
