Flap motor quit
My flaps stopped working. The wiring is good up to the motor.
An old timer told me to tap the motor with a hammer. I did and much to my surprise, the flaps started working. His other advise was good as well. He said "Don't trust them".
Are these the same symptoms as the grease contamination problem? I am guessing not.
Does anybody have a cheap source for the flap motor (assuming it is not the grease problem)? Thanks.

Motion Systems Corporation
If it's a Motion Systems motor and gearbox assembly - most are I believe - then they were very helpful when I broke the Brush Assembly on my motor when carrying out the "de-grease SB". They knew what I needed and supplied new parts the next day for not much more than $10 if I remember.
They are in New Jersey at (732)222-1800

Grease it is!
Follow the instructions on Vans web site clean it up and you'll be good to go.
I've had to do it twice.

mine quit too
On Wednesday last week my flap motor failed. It is a Pittman. I removed it and cleaned it per Vans SB. Re-Installed Friday. All is well. Wow it is great to be able to do your own service on your aircraft. A flap motor failure on my old 172 would have resulted in an AOG 172 for a week while the mechanics found time to work on it and then the bill would most likely have been $250 or more.

Do a search on the forum, you will find a number of threads on the topic and how to clean them.

You can also use your elbow....

Is it really grease?
Seems like a failure caused by the grease senerio would not be 'cured' by whacking the motor. Can anybody verify this? Thanks
FYI: I am the origional poster but was using a bud's computer.

WHACKING works when the brushes wear a little and are stuck in the holder and no longer have contact. Tap it and the springs will push the brushes out and you are good till they stick again, or till you fix them. |

If you end up needing a new motor you can get them here with the gear attached to the shaft.
Don't ask how I know.
