Was cleaning a floor drain and the machine stopped working. Took it apart and found the bevel and pinion gears were not touching, therefore, the cable could not spin. Has anyone had this happen to them? If so, what is the procedure to repair the machine? I just greased it up and the bearings look good. I think it may have something to do with the shaft and cone because the spring pin seems to be frozen into the cone and it is not aligned with the shaft key. If I need parts, where do I go to order them? Thanks.
