Title: 2150 piston ring
Post by: huckleberry on June 21, 2013, 08:18:58 pm
After pulling the cylinder off of the saw, i accidentally broke my piston ring. got a new one at the local repair shop. reassemble the saw and have very little compression. saw will fall from the starter recoil under its own weight. i tore the saw back down and put the ring alone into the cylinder and there is in excess of 3mm of gap in the ring ends. is this normal or is the ring too small. thanks

EDIT: This number is wrong for the original poster's application. This number is for the 44mm bore!!!!!

i have read that some of these saws came with a 44mm cyl and some with a 45. mine has 45L marked on top. could this be where we are going wrong. nervous about ordering the ebay one as it doesnt mention size....

Jim is the jonsered 2150 the husky 350?   

That would explain what I am reading on the 44mm 45mm bores

FWIW you can get about any size ring you want from Northwood saw ,cheap .Takes maybe 3 days to get it .

It's pretty simple ,you order the stuff on line and then if you want phone in the credit card number if you don't trust the internet which I personally do not .

Northwood Saw is were I get my cabers too.  Just make sure you get the cabers and read listing close. I have used the others with no problems too.

If you get Meteor or Cabers from the foreign countries across the Atlantic, it usually takes close to a month to get them.
