Any suggestions on what would be the best chain case oil to use ,i used to use amsoil full synthetic but had someone do some service to my sled didn`t have time to do it myself,he told me he changed the oil in the gear case and when i asked him what he Put back in there he told me a concauction of atf and some other oil i think this could have led to my bearing melt down inside the chain case,everyone i talk to have never heard of the bearing letting go inside the chaincase for the reason of they are always being lubricated by the chaincase oil,anyway getting ready to reasemble and would like to see what some of you are using for chaincase oil ,thanks.PROGOLD.

I use what ever the local shop has that week.....
I have had the chaincase bearing go once....
BUT...
It was not the fault of the oil..
We rode about 100 miles on a very cold morning...stopped for lunch which took about 1 hour...made it about 500 feet before.. crunch...clank...clank... WTF ?
It was obvious that the seal had failed on the ride in the morning allowing water into the bearing. It then froze during lunch.... why was it so ovious ?? Ice shunks IN the bearing.
I have run atf mixes...30w engine oil...etc. My findings is the sythetic results in less fuzzies on the dipstick....
So like he says..." Think with your dipstick Jimmy"

Anything
I personally use a fully synthetic oil ie AmsOil, Klotz, Maxxima or whatever the shop has that week as stated above. Since the chain case only get's serviced once a year I figure why not spend the extra $5 and use the best stuff. That being said, though I really don't think it matters much. The Yamalube chain case oil is really nothing more than 80-90W gear oil. ATF works fine also and is very cheap. Those bearings don't fail often but occasionally. I highly doubt it was due to the choice of oil in the chaincase at the time.

Use, a quality synthetic gear oil. Do not use ATF for trail riding, not enough fluid, to stay cool, once ATF reaches over 250 degrees it has lost just about all lubricating quality's. ATF is good for Drag races only, extremly low frictrion. If the concauction was so good why wouldn't it be marketed? Al

Polaris sells a full synthetic snowmobile chain case oil in a 1 liter/quart size for about the best price per unit volume I can find... Good stuff and reasonalble in price relative to other network marketed oils... Here in Canada, it's very expensive to get Amsoil of any form without feeling raped!..

You'll get many recommendations at what to use from motor oil to ATF,they all will work i guess the key is to change it often,,my self i only use a synthetic oil Amsoil severe gear 75w90,it has a pour point of -58 so it's thin enough to not cause rotating drag on the chain but loaded with EP additives for chain and gear longevity.
id stick with a syn gear lube $.02

I'm not disagreeing Al but do you think the chaincase sees those kind of temps?
Most four wheel drive trucks with automatic transmissions use ATF to lube the monster chain found within the transfercase. In fact, don't most modern manual transmissions use ATF as well?
