Default Flap Motor fix with Pics

So, once again I find my flap motor not wanting to go down, oh well, better than not going up after take off. I had cleaned the shaft of the motor before, but did not fully disasemble the unit to clean it out of grease.
So, out to the hanger I go to resolve this issue with hopefully a better result than the last time, it lasted 45 hours. First remove the flap assembly from the plane, hard to see in this pic, but there is quite abit of grease on the shaft. Some is good, but this was to much.

pull off center body that has the magnets, see on the top of the motor where the brushes contact the shaft, all gummed up with oily goop.

remove two allen screws from bottom of housing and remove screw unit

the larger hole was full of grease, this is what works up into the motor to stop the brushes from working properly. Clean out the excess grease.

Clean off as much grease as you can, but be sure to leave some on the shaft that comes out of the housing and atttches to your flap weldment. also, there are tiny bearings at each end of the motor, dont put anything in them to remove the grease in them. Clean off the ends of the brushes and shaft where the brushes touch. I used a light touch with a scothbrite pad. Assemble the unit, putting a drop of loc-tite on the allen screws( was on them when removed) be careful not to bend the little springs that hold pressure on the brushes. Some have diferent ways to hold these in when reassembling, I just used my fingers, no big deal. Re install and test, works fine. Hopefully doing the full grease removal will last a long time.

Best part, it was ony an hour job, start to finish.

This was how I did this fix and in no way am an expert. This info is worth what you paid for it. Use it wisely. Your mileage may vary

And now for something completely different.
