I had my Dillon CV500 motor go bad in 2008. I returned it to Dillon and for $30 including return shipping, they replaced the motor. Two years later the motor went bad again. I think the windings went bad, as when unplugged, the motor spins freely, but when plugged in, the magnetism locks up the motor. I called Dillon again. This time they wanted $105 to repair, which included return shipping. They said they found the original CV500 motors were not up to the task, so they upgraded to the CV750 motor. This required a different mount and base for the CV500, which is part of the reason the repair cost is so high. Dillon has no more of the old CV500 motors, (although I heard they did for a while, and were selling them off as DIY). The original motors were manufactured by A.O. Smith, made to Dillon's specs, as per the Dillon rep, and are not commercially available. I contacted A.O. Smith, and could not get one. So far I have been unable to find a suitable replacement in the aftermarket world. I'm sure there is something out there that could be adapted. I did the math, $105 to repair, plus at least another $20 to ship out, That's almost the cost of a new CV750! In the mean time I purchsed a Lyman 1200 for $42, which works great. I still have the carcass of the CV500, and maybe someday, if I need an additional tumbler I will breakdown, and send it to Dillon for repair. I would like to know where Eric got his replacement motor also.
