I have been noticing this winter that my oil in the chaincase turns white and milky, and that there is a significant number of metal filings on the dipstick compared to last winter. It also slowly loses oil from somewhere because I recently had to add some more to it. The oil in the chaincase used to be fine last year, black with a few metal filings, but when i changed the oil this fall, i have had problems ever since. I also am noticing a slight vibration by the foot stirrups, not sure where it is coming from though. Any help on this problem would be great. Thanks.

When i remove the dipstick after each ride though it is caked with filings and white/black oil. Something seems to be going wrong. I am going to replace the Jackshaft and Driveshaft bearings in the spring, does this require the removal of the jackshaft and driveshaft or can i simply change bearings and seals with it all in place?
Leaking: I think you know the answer here, you just don't want to accept it: you changed the oil and you pinched the rubber gasket somewhere - or its missing altogether. Any metal case with a metal cover must have a rubber gasket in between both surfaces, or the fluid inside WILL leak.
White and Milky: The last time I saw "white and milky" from my chaincase, I had just pulled it "out of the drink." Since you didn't mention sinking your sled in the nearest lake, I can assume that DIDN'T happen. If you just changed it in the fall, what did you replace it with?

There is a drain plug on the bottom, where no oil is coming out of, and that is all i removed to drain the old oil. I replaced the oil with Polaris Synthetic Chaincase Lubricant.

Milky, there must be moisture getting in there some how.

Also, having to keep on buying this polaris chaincase lubricant is starting to become costly and i was wondering if there is something cheaper out there that does the job just as good?
Ok, that's cool, no offense; I'm used to cracking open my chaincases to swap the oil, I guess I forgot you can sometimes just pop out the drain plug...
As for the oil you selected, maybe someone else can comment on that, as it looks like you ahve that covered as well.
Good luck.

Milky color would be the moisture issue already addressed. The vibration could be a bearing going in the chaincase. I would check to see if it is leaking out the back side of the chaincase through the back seal. If it is I would be doing some chaincase work before I rode again. I like the removing the cover when I change oil so I can inspect the chain, gears and see whats going on inside.
