I decided to change my own oil on my ’04 Sportsman 500 HO, thought it would be a nice afternoon project (mistake #1). My first problem was I couldn’t get the hose clamp off the screen fitting on the bottom of the tank, so I couldn’t get the screen fitting off to clean. Mistake #2, I took the hose clamp off the oil feed line into the oil pump. So now, according to the owner’s manual, I need to prime the system by clamping off the vent line on top of the oil tank. My million dollar question … how to I clamp that line, and how to I get to it? Do I really have to take off the front storage rack and the hood panel? An oil change shouldn’t be this difficult!
