i think my chain is screwed any tips are greatly appreciated
« on: September 08, 2014, 11:49:43 pm »
i was out cutting trees yesterday and my chain came off for the first time. i noticed the damage right away but i am just wondering if the chain is salvagable if i file down the burs, but am worried because i dont want the bad links to wreck my drive sprocket, any tips?

You could splice a section in but I would buy another chain and use that one for parts. The bar rails will be beat up, get that fixed before installing a new chain and keep it properly tensioned.

it was tensioned good when i started... it flipped off when i got it stuck in a tree and tried to work it out the lazy way instead of pushing the tree off of it. i put a new chain on after inspecting the bar, i didnt see anything majorly wrong with it, but if you can tell me what to look for i would be very greatful

Is the new chain jumping off the bar too?

Buy a couple wedges

no, i think the only reason the other one did was because it was wedged into the tree and while i was yanking and revving the saw it came off from sideload or something. i should have just wedged the tree and i would have been fine, i put the new chain on and cut another 10 trees or so, with a couple tensionings of course and never had another problem. but how do i inspect and identify bar damage? and whats the best way to fix it? also im assuming those teeth are chewed because i didnt hit my brake early enough after the chain jumped, correct me if im wrong

It usually messes up the chain one way or the other when it jumps no matter what you do.

You have to just use the old chain for spare parts.

The good looking drivers probably have dings on them too that will need to be filed off before they will fit in the bar again.

Look for odd looking places on the bar where the chain may have jumped off. Sometimes it will break out part of the chain rail.

I would look at the sprocket too?

The chain in the picture is no longer good.   Save for parts.

Most chains can be salvaged.  The cutters on that chain do not look like they have much wear; only 4 drive links appear to be damaged.  If you have a spinner and breaker, or know someone that does, those links can easily be replaced with links from a donor chain, or with identical links of Oregon chain (they made that Husqvarna chain), which is easier to find. 

Some dealers will do this for you for less than the cost of a replacement chain.  Some will not.

Chains jump the bar for a number of reasons.  Sometimes it is tension.  Sometimes they get stuck and pulled.  Sometimes small twigs get tangled between the bar and chain when cutting brush.  Usually, filing off any burrs on the drive links is sufficient to make the chain usable again.  Sometimes, bent links need to be replaced, if the chain was twisted.  In your case the holes in the drive links (Oregon Lubriwell™), designed to help carry oil around the bar, are weak points that sometimes snap off.

As I understand it, most of the damage to the drive links occurs from the sprocket, not the guide bar, so you may not see damage along your bar rails.

If repair is not an option for you, then replacement is your best choice. It might be possible to still run that chain with the rounded off drive links, and this may add some additional wear to your drive sprocket.  But sprockets, chains, and bars are all consumable/wear parts.  So that is up to you.

As noted, if you decide not to use it, save it for parts. Down the road you might run into similar problems (or hit some rocks) and find someone who is able to make the chain repairs for you.
