KCMongo,

Looking into it a little more, I believe you may have an earlier model of this winch (or one of similar capacity).

If you can, measure the main shaft diameter, drum diameter, drum length and input shaft diameter and compare them to the winches on the above site. You should be able to narrow down which winch you have.

You may want to get in touch with Tulsa Winches as they should be able to get you information about your winch. They probably still have some replacement parts in stock, or can get them for you should you need them.

In case you didn't know, the main gear inside the side case is made of a bronze alloy. You may want to take the top of the gear case off to check for wear. The side plug is the oil level plug. It only needs oil in it to that height. There are roller bearings on either side of the input shaft while the winch shaft rides on bronze bushings.
