Polaris Ranger 800 Transmission Rear Differential or Main Gearcase Oil Change: Capacity 1.1 Quart or 34 Oz.

The 2010 Polaris Ranger 800 transmission and rear diff oil run in what Polaris refers to as the main gearcase on the Rangers and oil capacity is relatively small at  34 oz. or 1.1 qt. AGL Fluid.  This oil change is relatively quick, but is messy and awkward getting to the drain plug and fill plug.  Removing the rear passenger side tire would allow better access to the plugs.  This article and the free video explains how to change the oil.

Before you get started make sure to have whats needed to complete the job.
- 8mm allen wrench    - 1.1 qt Polaris AGL Fluid    - oil catch pan   -flexible funnel or hose   - rags  

Before removing the drain plug on your Ranger drive it around for 15 minutes or longer to heat the transmission-rear diff or main gearcase oil.  Now remove the oil Drain Plug with a 8 mm allen Wrench and attempt to catch as much oil as possible.  This part made a mess on our Ranger 800 skid plate.  After draining remove the Fill Plug with the 8mm allen wrench.  The tricky part is getting the new oil back into the gearcase.  Some have claimed to fill through the vent hose, but we filled through the Fill Plug opening.  Our AGL Fluid came with a nozzle that was applied after removing the cap and breaking the seal.  After installing the nozzle we cut the tip and placed a foot piece of clear hose on it to feed into the case.  Our Polaris Ranger 800 used 1 quart, although specs claimed 1.1 quarts.
