I called Dilon for a new motor and was told the new case cleaner was upgraded and the new CV750 takes a different motor and I had to send it back to Dillon pay shipping both ways and send the $140 for the repair. Shipping both ways and $140 makes a new one a better deal but mine just needs a motor. The little motor it came with is and open frame with all the frame and coils showing. The CV750 had an enclosed motor and if I use the same specs as the original 1/40th HP 3000rpm 115 volt single speed I can find an enclosed motor with the same numbers. I am assuming that the enclosed motor will be more durable, than the original. Is that really the case? It may take some fabricating to make the enclosed motor work but looks like the open frame motor would be a direct replacement with no additional work. What do you all think?
