Interested in purchasing a 14/28v 430 or 530 (waas or non waas) for my 75 F model ranthony1@ca.rr.com Thanks....

Hi: I'm guessing that you have already sold this unit but if not, please contact me ranthony1@ca.rr.com. If someone else has a 530 for sale... I'm interested. Thanks, Ron

I had my airspeed indicator dial repainted and calibrated by my local instrument shop. I replaced the instrument and had the shop check for system leaks. It was determined that there was a pitot leak. After a little trouble shooting we found the leak was coming from the pitot system drain at the underside of the pilot side wing. The drain is a spring loaded valve that uses an "O" ring to seal the system. My "O" ring was shot, cracked in multiple places and falling apart. I'm guessing that it was the original "O" ring. Unfortunately the valve is a pain to get to. The pilot side lower interior panel has to be removed to access the valve which is buried behind tube framing and a couple of large wire bundles. It's a pain... but doable. Anyway, thought I'd post my experience with all the talk of system leaks in this thread. 75 M20F

It seems that others have installed salvaged yokes and control rods on their pre J model Mooney’s. When doing this, is it a "plug and play" job with the J model yokes, control rods, and the larger diameter control rod guides mounted behind the panel or does the job require modified fitting(s)/ connector(s) etc. that allow installation of the J model rods and yokes? Simply put, will J model yokes and control rods with the appropriate size control rod guides bolt right into my 75 F model without modification? Thanks, Ron 75 M20F

The wording from S-Tec is as follows; "This kit does not include switch installation data for control wheel, P/N 91720 used on M20C, S/N 20-1147 thru S/N 20-1185, M20E, S/N 21-1161 thru S/N 21-1180 and M20F, S/N 22-1179 thru S/N 22-1305. Control wheel may be replaced using Mooney Aircraft Company Drawing No. 940021. Retrofit Kit No. 946021-507 - this kit includes both pilot and co-pilot control wheel shaft." It just so happens my M20F falls in between the S/N's listed.

Thanks Ned! I know my yoke could be modified to accept the switches however the installer sent me the S-tec document showing the modification requirement for the STC...

After reading all the posts on this thread (201 style yokes on F?), I'm left with a couple of questions that I hope someone can answer for me. I have a 75M20F with the smaller diameter control shafts and the giant yokes. I want to install an S-tec autopilot and the installer is saying that S-tec requires the yokes be upgraded with a Mooney retrofit kit (just under $4,000) to accommodate the new AP switches. It seems that others have simply installed salvaged yokes and control rods on their pre J model Mooney’s. When doing this, is it a "plug and play" job with the J model yokes, control rods, and the larger diameter control rod guides mounted behind the panel or does the Mooney retrofit kit have some type of modified fitting(s)/ connector(s) etc. that allow installation of the J model rods and yokes? Simply put, will J model yokes and control rods with the appropriate size control rod guides bolt right into my 75 F model? Thanks, Ron 75 M20F
