I have a polaris cleaner that I thought was a 280 but now I'm not so sure. It's been running fine until a week ago when it shed an axle. I think I can fix it if I can find parts. The trouble is I'm not sure what model it is and I can't find a part schematic that looks like it, also I have no idea how old it is and the info molded on the bottom is scraped off. The unit has three wheels driven internally by 2 belts from the turbine. The wheels are on hexagonal axles. The bottom is white and the 2 piece top is blue held together with 1 screw. I think it may be an old version of a 360 or 380. I need a new bearing and cap.
