Does look like the spring is broken there where the coil is collapsed.
Check ebay for aftermarket springs, I see them advertised frequently. I haven't checked that close but seems they were under $300.
ok thanks for the tip

I recently purchased aftermarket springs, off ebay, for my 955H. They were $165 each. Plus shipping.
I had a broken spring on my 941b--it was broke in two places but i got 20 years out of it before it really let go---it all depends how carefull you are running the machine and not slamming the idler into objects.
and yes i got an after market spring on ebay for about $150--got the new bolt too.
I bought a recoil spring for my 74 A D-6 on Ebay For around $ 350 and freight .The other cost factor is that after you take a torch ,and cut it up ,break the track ,and get it out .The new spring has to be pressed to a demmension Cat dealers shop rate is $100 an hour .last estimate I got was it was going to take 2 hours shop time to press it ,plus your going to need a new center bolt and retaining nut I think that was $50 or $75 aftermarket So your going to have $7 to 800 dollars in it plus your labor in and out
Add to that would be a good time to reseal the hydraulic track adjuster while your in there.
Sprockets look good but the track adjuster is well out and the bushes look to be hitting the sprocket tips in reverse, I reckon the pins and bushes must be just about worn out, its worth checking further, the spring can be removed and refitted without splitting the track but put the gas axe through the old spring before touching anything else.
nice cat and fully dressed too! but i think this would be 3306 but could be wrong!!
