Changing the front differential gearcase fluid on a 2012 Polaris Sportsman is not a hard job. There is much debate about fluid compatibility, using the recommended Polaris Demand Drive Fluid or Angle Drive Fluid. The Angle Drive Fluid is a thicker oil and is used in approximately 2004 and earlier Polaris models that engage the AWD at the front hubs. These models have a larger bolt on center cap on the front wheels. In the newer models the AWD system is referred to as being centralized and engages in the front differential gearcase and uses the thinner Demand Drive Fluid. See the Difference between Demand Drive Fluid and Angle Drive Fluid here. We recommend sticking with the factory recommended Demand Drive Fluid. To watch the entire fluid change click here.
Before getting started have the following ready:
1. Polaris Demand Drive Fluid (9oz.)
2. 8mm allen wrench
3. oil catch pan
4. rags
Begin by driving the Sportsman 800 for a couple miles at road speeds to warm the fluid. Next park on level ground and removing the 8mm allen head drain plug located under the front skid plate. The drain plug is magnetic, check for debris and remember some build up is normal. While the fluid is draining remove the 8mm allen head fill plug located on front of the differential gearcase. Re-install the drain plug and fill the gearcase with Demand Drive Fluid, approximately 9 oz. or until it reaches the bottom of the fill plug.
