Misaligned Motor Mount: Uprading original 3/4 Hp Motor to 1 1/8 Hp Motor
Posted: Wed Nov 08, 2023 4:05 am
I am upgrading the original 3/4 Hp motor in my 1955 “Greenie” to the current 1 1/8 Hp motor that I purchased from Shopsmith.
I would appreciate help with an installation issue : Only three of the four holes in my motor cover align with the mounting points of the new motor. The mounting bracket attached to the rear of the new motor has two threaded screw holes, one near each end of the bracket. In my case, only one of the holes in the bracket can be aligned with one of the holes in my motor cover. The mounting bracket provides for some side to side adjustment but moving the bracket does not correct the problem. The front mounting points match perfectly, but only one of the rear matches. I do not want to omit a screw holding the motor.
The out of alignment is approximately 1/4” O.C. between the miss-matched hole in the motor cover and the threaded hole in the mounting bracket.
It seems likely to me that Shopsmith might encounter this problem when doing a motor upgrade for a customer. I have asked Shopsmith for a suggested solution and have not heard back. I have asked if there is an alternate bracket available that provides correct alignment. It seems to me that a motor that is a being sold as an upgrade should come with a mounting bracket designed to directly install. If no bracket is available, I've asked if they drill a new hole in the motor cover to align with the threaded hole in the bracket? I’d prefer to not drill an extra hole in my original Shopsmith motor cover. The bracket itself does not allow for drilling and threading a new appropriately located and threaded mounting hole. Other solutions??
I'd welcome any comments or suggestions.
Thank you very much,
Jim
