rear cowl flap motor issue

[B2C2]

Hi Herb

okay thanks, I will give that a try. The plane is going in for annual soon so Ill use the opportunity to have this done. I hate these intermittent problems. You are never sure if they are actually fixed.

[Jerry De Santis]

I agree with Herb. They are very simple motors and easy to have cleaned. Also, since your plane is not pressurized, I understand that there is a conversion kit that you can install and eliminate the motor. Maybe someone on this site has more information regarding it.

Cheers

I don't have that mod installed, so I can't comment on whether its any good or not, but $1495 is a lot cheaper than 7800 bucks for a new motor!

Looks like they do exchange/overhaul of motors too if it comes to that.

Try Georges Electrical Service in Sacramento CA 916 922-4277. The overhauled 2 for me about a year ago for $700.00 each. It may be more if it has a brake on it.

Make sure you check your fuses in the engine compartment for your cowl flap motors. Someone put fuses that were over three times the rated fuse size in ours. Check your manual for sizes.

I actually have a spare new one, Part Number C610501-0202 if that works for you. $600 and it's yours. After a cowl flap failure I used to carry it among other things on long trips to the middle of nowhere.

B2C2 -
I had the very same problem on my 69 D model a year ago: intermittent operation for a period of time and then stuck closed and wouldn't open at all. Before you dump a bundle on a motor overhaul/replacement, have your mech thoroughly check out the wiring continuity to the motor, especially in the rear engine compartment. There's a lot of heat and shaking back there that eventually causes problems.

We found an intermittent contact that finally gave up the ghost and now the cowl flaps work fine...(until next time anyway...). Also look for any hoses, cables, etc. that may be interfering with the actuator mechanism and putting extra loads on the motor. I have a Wolf oil filter adaptor back there and the feed lines occasionally work there way against the left side cowl actuator rod.

Good luck -
