Easy-peasy. Dry is bad for sure. Hopefully you just need chain and sprockets, if the bearings are bad then you have more work on your hands. Check them, top and bottom. Also of course the tensioner. Don't recall on these sleds what all has to be removed to access chaincase, just the exhaust can, and probably / maybe the brake caliper and brake rotor? Only remove what you have to. And the fact that it is dry may mean it needs seals too.
Thanks for the help!
No problem! If you search around a bit you may find a PDF file of the service manual if that would be helpful...
Yes, they can get that worn, but also if someone changed the gearing at some point it could be they needed to change the chain to a shorter one and didn't? In the downloadable owners manual from polaris (I think) it should show gearing and chain pitch count combinations that work also... or in the service manual...
And how do you check the bearings on the shafts? Just try and wiggle those sprocket wheels and see if there's any play in them?
That is the minimum, yes, but the drive shaft for the track may have enough tension that it may not show any play, look for missing seals, misalignment, wear or rust or anything that jumps out at you as unusual... the fact there was no oil in there is telling me there was probably a leaky seal at a minimum, most of those bearings have their own grease with seals on both sides, but the chaincase also has seals to keep the oil in, on both the jackshaft and driveshaft, I suspect you may have one or both of those bad. One way to tell for sure would be to simply add the appropriate amount of oil and ride it a bit and keep an eye out for leaks, once you get the chain tension issue resolved. The chain will probably wear out first like you have seen from a lack of lubrication, but I haven't had that happen so I can't tell you for sure...
He is definitely Gen2... had a 1999 600/700 back in the day, edge came out in 2002 in most RMKs IIRC
