looking at front of hitch: on left side there should be a pop out hole cover (unless your battery is mounted on top of your winch.) If that is the case, remove the battery box and note the hole, or covered hole, on the left side. Down in that is a bunch of grease. Embedded in the grease is the top of the winch motor shaft. It has a worm gear welded on to the shaft, and a 1/4" bolt with a hex head that a 7/16" socket will fit. You'll need an extension for your ratchet or drill to reach it probably. I use a 12" extension on my drill, but I am reaching down through my battery box where I cut a hole out for this purpose. Advice: DON'T USE A DRILL ON IT UNLESS YOU KNOW FIRST THAT THE MOTOR WILL TURN. OTHERWISE YOU WILL SNAP OFF THE 1/4" BOLT WITH THE 7/16" head. (First hand experience). My motor was all crudded up inside, and frozen on the bottom end of the shaft. I disassembled the motor, cleaned it up inside good and put a little grease on the end of the shaft, and put it back together. I had been able to grind the weld off the bolt which was left in the end of the shaft, and even screwed another in. But it immediately unscrewed when I put a drill on it. However, I got the motor to work just fine, and it raised my camper flawlessly. I have another ordered though because without the 1/4" bolt with the 7/16" head you're screwed if you're out camping. There is not enough protection from the weather for the motor if your camper is parked outside, so I have to come u p with a solution for that.
