Gear issues on PA-32R

Donald Fischer

Hey folks im looking for some insight on my landing gear issues!! My power pack went bad and i sent it in to get overhauled. after reinstalling the gear would cycle up and down just fine. the problem im having now is the gear motor will not shut off after the gear is up. We are thinking the high pressure switch went bad in the first place causing the gear motor to run continually causing it to burn up. Is there an easy way to test the pressure switch? Any help would be great! Thanks

It may be the new pump can't make the required 1600 - 2000 psi to shut down the pump... or the pressure switch may be bad. New ones are expensive, so you risk that cost if you buy one. Or, you need pressure gauges capable of 3000 psi to test and see what it goes to...

You might buy a used one from Wentworth to test and see if it fixes it.

Do not run the new pump real long under heavy pressure as they will overheat and fail...

I will attach the troubleshooting page on the subject.

Here might be a cheap way to find out....

thanks fly guy don. i had seen that on ebay before as well. one concern is that the switch i took off is a 1800 psi switch and that one is 1400. i dont know if a 400 lb difference is critical or not. i would sure like to give it a try due to the fact a new one like i removed is back ordered for 2 weeks, and expensive!
