husqvarna siezed

[jplen]

Hey, new to the forum looking for some advice, i brought my 365 special into a hire shop/husqvarna dealer for a new chain, without asking me he ground out the oregon bar to suit a stihl chain, i wasn't to happy about it but he said its normal he dose it all the time and he has a special disc to do it. Has anyone heard of this? is it ok? Now the engine has sized after not much use since then, He says it over heated from being worked too hard, said the clutch was black and the barrel and piston seized, and wants me to pay for the repairs. It was defiantly not being worked hard and he checked the fuel himself and said the mix was perfect.

What do you think?

ive never heard of grinding out a bar!

That's a first for me. Never heard of grinding a bar to suit a chain.

 

The chain suits the bar and visa versa. You buy the chain that suits the bar that suits the sprocket. So even if he did grind the bar to suit a chain the chain may not suit the sprocket.

 

The seize could Down to a lean mix. Not sure where he got overheating from. This only really happens from a gunked up cooling fins/flywheel area. Or a lean running engine.

 

Where abouts are you located? Could be someone local who could give some advice to you.

 

Remove the exhaust and get some pics up of the piston looking through the exhaust port on the saw. Unless its already apart. In that case get some pics of the cylinder barrel and piston.

Do you know if he took the nose sprocket off the bar and ground the nose of the bar too ?

I can't see grinding out the rails of a 1.5mm bar to accept a 1.6mm Stihl chain is an acceptable practice - I have certainly never heard of it before - sounds a bit of a bodge to me as it would make the rails thinner and what happens at the nose sprocket?

 

Why didn't he just fit a 1.5mm loop, sounds like it is just so he can hold less chain stock and he shouldn't have done this mod without your authority.

 

The black crap around the clutch is probably where the chain started binding in the rails making the clutch overheat and slip - not sure if this would seize the engine or not is debatable but I would check to see the fit of the chain on the bar and see if it is an overly tight fit or not and see if it spins around it freely.

 

All sounds mighty strange to me:confused1:

I think the bloke is feeding you absolute BS, stihl make chain to fit husky, so the bar wouldn't need grinding, I have never heard of the internals of a bar being ground out

JUST FELL IT :lol::lol::lol:

 

You know what that means.

 

Just a thought to the op. has the saw actually seized or ha s the clutch overheated and stuck on making it feel like a sieze???

 

There is something very very dodgy about the grinding bit I'm afraid and its starting to make me suspicious......

Cheers lads, he still has the saw in the shop im going in to him in the morning, i don't think he ground out the bar nose, and i don't think there was much dirt in the fins but ill check that tomorrow, im near Dublin. Will try an get some pics tomorrow.
