craftsman garage door opener

After replacing worm gear and very worn down drive gear, I carefully reassembled my 13 year old GDO. Initially, the motor worked fine, but the door only went up about five inches. Then, with chain off the sprocket and the trolley in door-down position, I pressed the wall control again and got very short (1 to 2 second) motor activation, and then nothing. The new gears did revolve, but only slightly -- for the very short time the motor ran. I tried repositioning the black cover on the motor shaft and reinstalling the four prong part next to the cover, but this didn't change anything. I'm not too technically adept -- the instructions that came with the replacement gears just about maxed me out -- so any relatively easy to understand help anyone might offer will be greatly appreciated. Thanks very much.
