Trailgroomer,
Sorry, but from the information you have posted, it's hard to tell just what parts you need. The bearing that went out, and the shaft that it damaged.....fan pulley....are you talking about the water pump? I think the engine is a Ford product, and perhaps an automotie parts store could fix you up. Or, is there a belt tightener on the fan belt that has gone bad? You will get very good help here if you can tell us more information about what is wrong with your rig. From our experiance, Ski Dozer parts are still availble, new and used. So give us some more, and someone will give you an answer.
Regards, Kirk
