hi. i am new to the forum. i own a 2001 wolverine 350 4X4. question is what kind of fluid goes in the differentials? and also how full should they be. am waiting on my manual since everyone had to order it. any help you guys could give is greatly appreciated.
thank you

 

The manuel recomends SAE 80 or 80W 90 API GL5 Hypoid Gear oil for LSD (limited slip diff). It should be filled right to the bottom edge of the fill brim of the fill hole.

 

For the rear Yamaha recommends SAE 80 API GL-4, you can use an SAE 80W-90 as long as it indicates that it meets API GL-4. Also when filling the rear diff, do not fill it to the brim of the fill hole, doing this will cause gear oil to be pushed into the vent tube for the rear diff and it will end up venting the fluid under the seat next to the air intake for the engine. To prevent this from happening fill the rear diff by the volume of fluid that is required, which is 0.20 quarts. For the front Yamaha recommends either SAE 80 or 80W-90 API GL-5, it also requires an additive for limited slip differentials. I typically use Mobil 1 75W-90 because it has the limited slip additive already in it, you can also you the same Mobil 1 gear oil in the rear diff as well. The front diff can be filled to the brim of the fill hole without any problems.

 

thanks for the info. it is greatly appreciated!!!!
