Well I've had my first experience with a Husky plastic crankcase and I have to say this has turned me into a mag only man.
I picked up a nice (so I thought) 345 on ebay and as with all my ebay saw purchases I buy them with the assumption that they may need a new piston and a cylinder clean-up regardless of what the seller claims.
Sure enough I got the saw and wow, it is in excellent shape. I proceeded to pull the muffler to have a peak at the piston. There was some minor scoring on the exhaust side of the piston but terrible scoring on the intake side of the cylinder. So I figured I would tear it down to take a better look to see if the cylinder could be saved.
When I was trying to get the cylinder off the base it seemed stuck on one side which I figured may be sealant. After wrestling with it for a while I was able to break it free. So I found out what was holding the cylinder, the crankcase bearing seat on the clutch side was actually melted into the crank bearing seal.
So now I have a bad piston/ring, bad cylinder (not so sure it would clean up), and bad crankcase.
Now the bearing seems to have the seal factory molded on it, is this correct?
At this point I think this is going to be a parts saw but what a great first hand experience with a plastic crankcase.
