Well I got the motor back together. I decided to leave both O rings out. When I put the slinger on there was no interference so I just tightened up the set screws.
I put the motor on the gear box but I'm not getting any mesh between the motor shaft worm and the gear box worm gear.
Paul - did you have to do some adjustment to that and, if so, what was it. It seems the only adjustment is to slide the worm gear in but I can't get it to move?
Thanks
Rick
