SPEEDMOONEY Posted July 29, 2020 Report Posted July 29, 2020 Is anyone know where to find spare fuel valve selector Air Right PN 36100-12 for a M20J 24-3187 ? Quote
Bob - S50 Posted July 29, 2020 Report Posted July 29, 2020 Call every MSC. I did that and found exhaust hanger parts after calling only 12 of them. 1 Quote
carusoam Posted July 30, 2020 Report Posted July 30, 2020 We have a few options... New... ask Dan at Lasar... Used... @Alan Fox @Jerry Pressley @SheryLoewen That’s the short list... If you acquire an old one... it can be OH’d by Lasar... PP thoughts only, not a mechanic... Best regards, -a- Quote
N177MC Posted July 30, 2020 Report Posted July 30, 2020 (edited) I spoke with Dan @ LASAR just yesterday about this. He was NOT very optimistic: - These selectors are NOT servicable/re-buildable - Mooney has "in-definite" lead time for new. - Only short-term remedy is used, but beware of junk that's no better than what you have ... - Edited July 30, 2020 by N177MC Quote
M20F-1968 Posted July 30, 2020 Report Posted July 30, 2020 I have a fuel selector from a 1998 Ovation. 400 hours of use. Can it be used in your J? I can get the part number if you wish. John Breda Quote

Flymu2 Posted August 2, 2020 Report Posted August 2, 2020 I had one fail on an Eagle a few years ago. Tried in vain to find one other than new. Finally had to cave and buy new. $1500 plus install :-( Quote

Are you saying that the OEM fuel selector was replaced to allow for the “fuel return circuit”? Thanks for information. Quote

If you have a Continental engine, I have an fuel selector and separate gascolator which are almost new - 400 hrs TT. Are you sure you have a J model with a Continental? The selector I have came off a 1998 Ovation. John Breda Quote

I don’t think I can stick that selector in there and ours is working fine, but I had not read anything in the logs/Rocket Engine Conversion that discussed the fuel selector being swapped. That was the reason for my question. Thanks, Scott Quote

Every fuel injected Continental engine I’ve worked on have a fuel return circuit from the engine fuel pump, to the selector valve then back to the selected tank. I’ve never worked on a Missile, but I’m betting that they installed a K model selector valve and fuel lines. Clarence Quote

Appreciate the reply sir. Quote

carusoam Posted August 4, 2020 Report Posted August 4, 2020 Part of the Continental engine installation is its fuel strainer with fuel delivery lines... The IO550 has a full return line... used for improving hot starts... eliminates vapor bubbles in heated fuel... Ovation fuel selectors include this line and put the returned fuel back into the same tank it came from.... Other installations may return the fuel always to just one tank.... not using the fuel selector valve... Oddly enough there is still hot fuel that goes beyond the return line... but a small amount...

Missile=Awesome Posted August 4, 2020 Report Posted August 4, 2020 Clarence was 100% correct...as usual Quote
EricJ Posted August 4, 2020 Report Posted August 4, 2020 lol...that also answers a question from another thread, that there is an additional bar in the cage for the increased gross weight in the early s/ns, and gross was only 2837 for those cases with a stock landing weight. Interesting. 2 Quote
N177MC Posted August 29, 2020 Report Posted August 29, 2020 (edited) SIX weeks later and still no solution for this fuel selector valve, despite contacting Mooney, Maxwell and LASAR ... HELP ! We have found fuel valves for late model Conti engined and pre-J model valves as well, BUT NO J Model fuel selector valves and the word on the street that re-build/overhaul is NOT an option. Just to be sure, here's the photos : Edited August 29, 2020 by N177MC Quote
PT20J Posted August 29, 2020 Report Posted August 29, 2020 Does it leak? Is it stuck? Or, just difficult to turn? At the museum, we work on a lot of old airplanes that are difficult or impossible to get parts for. These valves are pretty simple. Often just taking it apart, cleaning it up and replacing o-rings and lubing it with EZ-Turn gets them working if they've gotten stiff or frozen. Skip Quote

LASAR told me that these valves are NOT repairable and I cannot find a single shop that will even attempt a repair, otherwise I would have done it from the start. Quote

Did you try to pull the snap ring to take a look? Maybe parts inside can’t be replaced, but a clean and lube could fix the problem. Quote

PT20J Posted August 29, 2020 Report Posted August 29, 2020 I haven’t worked on this particular valve, but a lot of these type valves are tapered plug (aka cone) valves. They can be disassembled and the plug and mating surfaces VERY lightly lapped together to make them turn freely. Don’t overdo it or you will make the cone undersized and the ports will be misaligned (yes, I’ve made that mistake). All you want to do is remove the surface toughness that is preventing the valve from turning. Replace any o-rings and lube everything with EZ-Turn (aka Fuel Lube). I would remove it from the airplane and get it up on a bench where you can work on it properly. We had to do this recently with a stuck firewall shutoff fuel valve on our Beaver. Any time a metal valve starts getting stiff it’s a good idea to take it apart and lube it. They just get worse until they finally seize up. Good luck. Skip 1 Quote
