I just recently bought a 1993 XLT 600 SP and I checked the oild in the chain case and it was sludge, could it be from just sitting for a year or could water have seaped in there. I'm planning on draining it, cleaning out and adding fresh oil. Will this help or do I have other worries, I've heard these are famous for the crank bearings going out, is this a sign? Thanks

if you would like people to resond to a poll, you might want to think about putting answers, that are relevant to the questions

Its probably just water that seaped in there. Clean it out, check gears for missing or damaged teeth and check chain for damage to links. If everything is good then put cover back on with a new gasket and refill. If theres water in there again in a couple weeks there could be larger problems.

And welcome to Snowmobile Fanatics. Its a great site with loads of very knowledgable members. Stick around and youll learn a few things.

if it is a 93 it shouldn't be a 600 it should be a 580 unless someone did a swap

It can't have anything to do with the crank, it is not attached to thr engine.

I would say that there is just old oil in it. Since it's a '93 you probably don't have a drain plug on the bottom side, but you can always check to be sure. There will be a hole in the plastic bellypan that you will be able to see a plug that will require an allen wrench to remove. If there is no plug, you will have to pull the dipstick, suck out as much of the old oil as possible with a suction gun, then remove the chaincase over. Clean as desired. Re-assemble and refill with the proper oil.

You will find that most of that sludge will most likely be metal shavings. Don't panic, it's normal... unless it's excessive. Good luck.

Not to hijack this thread, but I had to comment on this...

Clouse, just how does your response here help this guy with his problem? In 1993 the XLT SP was listed as a 600 even though the engine was, in fact, a 580 cc engine. Just like in 1995 the 600 still wasn't truly a 600, but a 597. Even in todays market, the sleds are not exact cc for what they say on the hood. Your response (much like mine to yours) had absolutely no point in this thread. He didn't ask if his sled was a 600 or a 580, he wants to know about his chaincase. If you don't have anything relevant to post... don't.

I think that is what happens when a sled sits all summer.

A couple random thoughts.... If it's a 580, no problems with crank berrings. They were great motors.

The chain case lube is probably just kind of old.

I have a feeling that this is a poll and not a regular topic because the original poster accidentally clicked New Poll, and not New Topic. Give him a break, he's new here.

Welcome Aboard, Chris.

what happens in your chaincase and what happens with your crank are two separate things. as for the chaincase an oil change and a chain inspection will be all you need.
