Front Cowl Flap Motor 1976 P337

Those motors are very simple units. Don't be afraid to take it apart. Most likely requires only cleaning. Just be carefully re the head with gears in it.

Just to pass on, I checked today but Mr. Bob Bena is no longer working on these cowl flap motors. I'm trying to get ahold of Matt @ MaxQComposites. I was looking at the manual conversion, but I few people have commented that they have had trouble keeping them completely closed.

Totally agree with checking the wiring at the micro switches. I had this happen. There are two switches per motor with three connections on each. If a wire comes off one of those switch terminals, don't remember which one, the sensor will not tell the motor to rotate to the closed position. Same of the closed to open position.

Grab a mirror and flash light and take a look.

Hello mshac,

I'm still checking with Matt also, but how much do you want for a rear cowl flap motor? My aircraft is a 1966 337A if that makes a difference. Do the motors come with gear teeth?

I have a C62-1 (Alt: C610501-0102) cowl flap motor in tagged, AR condition.

Bench-tested, working smoothly with no abnormal sounds.

$1200 plus shipping.

After having the motor removed by my mechanic today, we discovered that the pin on the rotating arm had been sheared off. The arm has to be installed so that the limit switch can stop at the fulling open and closed position. It was not. So, we installed it again and found the correct position for the pin, now it stops at the fully open and closed position. @Mshrc, thank you for the help.
