In this video I walk through how to change the oil on a Polaris Sportsman four wheeler. I cover draining the oil tank, draining the crank case, changing the oil filter and cleaning off the oil screen. Some people who own a Sportsman don't even know where the crank case drain plug is located, let along how to remove it. The four wheeler in this video is a 2003 Polaris Sportsman 500, but I assume the process is going to be the same on most other Polaris quads. I'll be adding this and other ATV repair videos to the Polaris Sportsman Repair Guide play list.
