Mcstealth Posted January 1 Report Posted January 1 Good morning. What do you think could be the problem?: The symptoms are the door will not open, obviously. The movement "up" is at a snails pace, the chains barely moving. The motor is spinning and sounds normal. The "down" movement seems normal, but I am assuming that is because of the weight of the door itself. No mechanical grinding or obvious bad noises of any kind. Quote
Fly Boomer Posted January 1 Report Posted January 1 Looks like there is a gear box. Can it be lubricated? Quote
N201MKTurbo Posted January 1 Report Posted January 1 There is probably a coupling between the motor and gearbox. I would check that it isn’t loose and slipping. 1 Quote
FoxMike Posted January 2 Report Posted January 2 Brushes in the motor or low voltage into the motor. Quote

N201MKTurbo Posted January 2 Report Posted January 2 The lift mechanism is coupled to the box on the side. It probably has the limit switches. I would look in there. Quote
1964-M20E Posted January 2 Report Posted January 2 You say the door is not moving then say movement is slow going up????? pop the gear box cover off and see what is and isn't moving. Then as above make sure everything, gear box, wheels, strap roller bearings (pillar blocks probably about 10 of them the length of the door) are well lubricated. Quote

The motor is turning, the door does "move" up, but I am talking millimeters here. We took off the capacitor cover. There are two capacitors and one is rusted through. Going to replace it as a matter of good practice. See if that helps. Edited January 4 by Mcstealth Quote

Shouldn’t but what the heck it’s rusted easy and inexpensive, due to the rust it ought to be replaced anyway. Assuming the motor sounds normal, my bet is the drive is slipping, sheared key or something, it ought to be real easy to see. I don’t think it’s the gears, if you broke a gear you can tell from the noise it makes, but it could be a gear slipping on its shaft 1 Quote

Put it on and it did not work They did some more tracing and found out. The actual switch on and off switch was bad. It is an old style switch that is not found everywhere. But they should be back today to install it. the saga continues. Quote
A64Pilot Posted January 13 Report Posted January 13 So the motor wasn’t running? Is your airplane trapped until then? Quote

Everything has been trapped for two full weeks now. The motor did make noise when the tech's came out. Slightly perturbed but only just, because we probably could have caught the on/off switch problem if we were not so short sited and lacked thoughtfulness. Yucky capacitors, wonky motor, should have told us to keep poking. Edited January 13 by Mcstealth Quote
A64Pilot Posted January 15 Report Posted January 15 Just curious, is this your hangar as in you own it, or is this rented? Quote

Finally, the little piss-ant threeway toggle switch, something that looks like I could have found at Grainger, showed up. The damn hangar is opening again. Now the gears are grinding.
