After installing the new hydraulic motor and top drum it became obvious my three pillow block plan to align the new motor wasn't working out well. Two pillow blocks on one side worked on the work bench to align the motor. The two opposite sides of the drum however, are adjustable for belt tracking with a tube-in-tube arrangement. That doesn't work with three pillow blocks on the same shaft unless the double pair with the integral motor mount are mounted on some type of swivel. That could be done but adding the swivel would change the height of the drum unless the existing tube-in-tube mount for belt tracking is modified. Adding the swivel on the reese tube might work but there is not much room, and the adjustment push plate would need relocating somehow.
At this point I may put it back together as it was originally, with a solid coupling and cantilevered hydraulic motor, and see if the motor shaft shears again. Or rather, when...it shears again.
I guess I don't understand how it worked as long as it did, because any belt tracking adjustment would seem to mis-align the motor and drum shafts.
Going to head out and give it one more go with aligning the three pillow blocks before pulling the drum completely out again.
Any comments, or suggestions to try a new approach are very welcome...
Same for any photos of your conveyor hydraulic motor mount if you have one.
