Rated 1 out of 5 by i chose one star, why? it just doesnt work, we have bought over one hundred of these motors, the 5k660 was great until now, we got 2 more in today, went to the job site, installed them, and they malfunction right out of the boxthe 5k660BB is the new model which replaced the older unit, the new one is a different design, and is made cheaply, we use the 1/2 hp model because an engineer calculated our needs to be less than 1/3 hp and we wanted to be overpowered so we would never have issuesmaybe these new motors dont make the stated 1/2 hp, or they are just junk, but i have to take both back, and i wasted 12 man hours, which i have to pay for, not counting drive time, these have cost me hundreds of dollars!
