answered on dootalk. 75W90 synthetic gear lube
The 1979 Scorpion 440 TK snowmobile typically uses a lightweight gear oil for its chain case. A common recommendation is to use 75W-90 gear oil, which provides appropriate lubrication and protection for the chain case components. Always consult the owner's manual or a service guide for specific recommendations and to ensure compatibility with your snowmobile's system.
Well, In my opinion the Polaris is the most popular snowmobile for its big brand name.
