knackered my bar today

[testcricket01]

Mine would only really be turned when I sharpen by chance, I always take the bar off and clean it, so it will get turned by some average, based on likelihood of putting it back on the same way again:001_smile:

 

If its gone slack during use, (excluding new chains for now) I would tighten it, and it wouldn't occur to me that, that could happen.

 

What make is it ?, I saw a bar on one of them echo saws do that after just a few uses

 

its a husky bar.

i have found over many years of repairing saws that if the sprocket at the bar nose is greased when new, providing the saw is oiling properly it does'nt need greased again and will last the life of the bar.

if i was put to task

i would say too tight

if its splayed it,s too tight

if it was grease related why would it spread like that

if it had not been turned why would it spread

too tight or something got caught in the sprocket or chain got damaged but those are ending up making the chain tight

just my opinion

looks like your bar been getting a bit hot i find the oregon bars if that one last well and paint stays on for a while if been looked after and not used when blunt,i have had the od sprocket go over the years mainly when the bar getting old or run dry ,or pinched,i grease it every day sometimes twice but sometimes these things just happen:::

 

Thats it mate, I reckon its time to buy a new one too, not much life left in that one:biggrin:

I always grease them, got to prevent so much wear and tear. So much pressure on those wee bearings, going to generate a fair bit of heat without grease. In fact I stuck a new 18" bar on the 357 yesterday, didnt have any grease with me, and the nose wheel stuck solid, cleaned it last night, pumped it full of grease and she's a good un again. Dunno why none of the Stihl bars have a grease hole, but the only bars I've had split open have been Stihl.

we have had this happen twice with husky bars recently, never with sthil and they have a lot more hours on them + sthil bars we dont grease

if it was grease related why would it spread like that

 

I dont understand it, but anecdotal evidence shows that starting to grease a bar halfway through its life as it were can cause that problem.

 

Having said that i think that chain tension could be a factor. Maybe it was a friday afternoon bar. A chap i know recently bought a baby stihl to do hid firewood with at home, and after about a month it split, and i know that the saw was set up right.

little jonny says

look after your tackle and it will look after you

abuse it and dont maintain it and buy a new one:thumbup:

If theres a grease hole, I grease it, they're put there for a reason.

Has the saw been dropped on its nose??
