I purchased a Dayton 5K942 gear motor. The motor had burned out--windings on one side. A friend took one look at it, and said why did you get the gear box? Well, I'm certainly not experienced with motor, so that's my answer. As I understand it from Grainger, the price breakdown if $185 for the motor, and $100 for the gear box. At this point, it doesn't make sense to return it. However, it might make sense to take the gear box off in case the new one fails sometime. It looks like about 7 screws hold it on, but there's a coupler on the shaft that has no apparent way to remove it. Maybe there's some sort of key shoved into the space between the shaft and the coupler. I'm not even sure removing the 7 screws would do the trick.
Any suggestions on the above regarding prices, purchasing just the motor, or how to get the gear box off?
