I wonder where that "info" is from, as it doesn't add up with anything I have heard or read before.....

 

I'd not heard that either . If it were true you would have thought more folks would have said ........

 

Yes, surely!

Xtorque is same as Stihl 2 mix, correct? I think this technology is really good for two strokes, my Stihl 2 mix gear is far superior to the old stuff. Much more power and economy.

Sort of, except that Stihl can't use the best "strato" technology, because of patents held by Husky.

I've got a 2012 that's quickly developed a sort of echo/rattle sound and it seems to have a lot of vibration on the flywheel side.

I thought it could be crank bearings, anyone got any experience of anything similar ?

Take the recoil cover off, hold the nut in the middle of the flywheel and wobble it up and down and side to side. You should feel no movement at all. Also check the fins on the flywheel are all there and that the flywheel isn't clouting the coil.

 

The bearings are usually strong but can be knocked out if the flywheel has a fin or two knocked off.

 

The noise you describe is classic crankcase bearing failure - a sort of hollow echo rumbling noise.

Thanks spud, I'll give it a try. I was going to ask you direct but didn't want to bother you.

I know my description of the noise wasn't very good though !

Even though it's only 2 years old it's done its fair share of work. I'd be surprised if it was the bearings but it's the only thing I could think of.

If the bearing is shot, don't use the saw as the crank will move too much and start putting pressure from the piston to the cylinder and may cause premature failure of the top end as well.

 

Crank bearings are not that easy a job to do but worth it on a saw of that value.

I've just done what you said and no movement on the flywheel side but there's play on the clutch side for sure.

I've done bearings on stihls but never on a husky, I'll see how I get on and report back. Thanks for the advice.

Only 2 faults ive heard with the x-torque 372 and that's the a sort of clutch drag due to clearance issues and somehow some main bearings not sitting straight into the crankcase due to a bad casting issues. Im sure both have been sorted now.

The greatest load is on the clutch side, in some cases it is the bearing loose in the crankcase not wear in the bearing, this would then need a crankcase, hope for your sake this is not the case.
