so you mean there are actually saws out there that Do have plastic (or anything non metal, whatever you call it) crankcases?!?!? Wouldn't this make them a structurally a (light) POS?

There's millions Fords, Toyotas and others on the road with plastic/composite Intake Manifolds. I don't see where it's a big deal, it's lighter.

But not a structural part either.
I remember when the 3.0L Duratec would blow the intake to pieces when they backfired.:jawdrop:

I'm not all that familiar with the structural design of other manufacturer's lower end saws.

How long do they expect these plastics to last? Do they expect people to treat them like new-borns? Not that i was ever planning on getting a husky though
Here is a 455 rancher that lasted about 3 months after I found the crack. It was cracked to the black line and it finally made it to the crankcase and had bad air leak and died.......The owner said he would run it till it died.....It sure did......

Thanks Steve for the pics.
And to think those scandinavians have the nerve to pick on the homeowner stihl saws.

plastic crankcases
My uncle has a 45 Special Husqvarna with a plastic lower crankcase that is 15 or more years old and goes through 3 chains a year, has had a tree on it and shows no sign of failure or slowing down.There are good ones and bad ones in every bunch.I've seen magnesium crankcase flaws as well as the ones shown on the 455 rancher.

And to think that Troll gives me a hard time about my Jonsered 2036. Hey at least it has a metal crankcase. That looks like junk to me!
Looks like the 45 crank bearings are mounted in metal collars .

It seems a little strange to me the way a lot of people slam the MS250 and praise the 350 when there looks as if there is no comparison in build quality. I guess some people would rather have speed than quality.
