Before getting started have everything you need on hand.
-Polaris Demand Drive Fluid (7.5 oz)
-8mm allen wrench
-catch pan
To make the fluid easier to drain warm it up by driving the General around for a couple minutes. After warming it up park the General on level ground and place the catch pan under the front differential. Next remove the 8mm allen style plug from the bottom of the differential, it's located via a hole in the skid plate. As the old fluid drains remove the fill plug, it's located on the passenger side of the differential unit and is also a 8mm allen style plug. Once the fluid has drained wipe any debris from the magnet drain plug and reinstall. Some small debris is normal, but large shavings may indicate a problem within the gearcase. The creative part is filling the differential with 7.5 oz of Demand Drive Fluid. We general use a hose attached to the filler neck as seen in the video, but others have used turkey basters or funnels. Once the front gearcase is full the fluid will be at the point of coming out the fill plug.
We would suggest performing this maintenance every 25 hours of use. This may seem like a lot, but the front gearcase or differential is a costly repair. A good maintenance routine can save big bucks in the long term.
