Directions for C/E to Lortone motor swap

Here's the photos from when I did it:


Here is the tumbler motor before the swap:



I removed the motor and clipped the wires. Here are the motors, old and new, side by side:



The C/E motor has #8 bolts that cannot be used with the new Lortone motor which takes #6 bolts. The existing Lortone bolts are too short. I purchase 3 inch #6 bolts from Lowes hardware along with lock washers too. I installed these new bolts on the Lortone motor with the plastic spacers from the C/E motor too. The holes on the spacers were a little too narrow, I used a drill bit to ream them out a little bit. Notice how long the 3" bolts ended up (Lowes only carried 2" and 3"). Also notice how the length varies (2 bolts end up protruding longer).



With the new screws, the motor wouldn't fit! I even tried removing the large pulley and there still wasn't enough room to get the motor in place.



I used my Dremel to trim the screws to the right length. Notice how I put the nut on first so that I could back it off afterwards to clean the threads.



Now, I was able to get the motor in place (be sure to install the pulley!). The problem now was that the belt was too loose even with the motor pushed to the far end of the slot!



I removed the motor again and used my Dremel to extend the slots on the tumbler body about 3/4". Now the motor installed perfectly with just the right amount of tension on the belt. I used wire nuts to connect the two power wires and screwed the green ground to the motor body. I guessed right on the order of the wires because the barrel turned in the same direction as it originally did. The new motor is very quiet, BTW.
