The weather seal already has holes in the aluminum? If so the putting shims into the gap would likely be fine for the side seals. The top is usually where you would have trouble with bad mounting. There is almost no force on the side unless you put it too tight.
I had this on a bunch of motors on commercial door operators. They had a bad batch with switches that wouldn't switch over. About 1-3 seconds and it would trip the breaker.
It is my understanding that normally when they fail they give some sort of warning.
Flickering.
Buzzing.
Delayed start.
Low output.
Inconsistent lighting levels.

A proper length of cable should have 3/4" of a wrap on it when installed properly. That last quarter of a wrap on the slightly raised portion of the drum will almost not even affect it. Especially when we are talking about what he is planning to do anyways.
For a standard lift door the cable length does not make a difference. The diameter doesn't change therefore there will be no difference in applied torque. High lift and vertical lift drums are different. The design of those allows the torque to be maintained even though the weight stays the...
I was working on a commercial construction site once when there was a bunch of yelling and screaming. A guy bursts out of the electrical room on fire and mostly burned over his whole body. Apparently he was pulling the main feed and the city switched the power on to the wrong building while he...
