MB65E Posted February 5, 2015 Report Posted February 5, 2015 I think the MTBF is 50 years! Glad to see they are available again. That was not the case 2-3 years ago. Good leg work -Matt Quote
RobertGary1 Posted February 5, 2015 Report Posted February 5, 2015 Did Mooney change the format of their S/N's at some point. I'm looking at the serial number range the SB applies to and the format is very different from mine. My SN is 22-1421. The SB applies to SN 680001 - 680206 and a few other F's. Does that mean it doesn't apply to me or that there are two SN's? -Robert Quote
scottfromiowa Posted February 5, 2015 Report Posted February 5, 2015 Good thread. Coming up on 50 years. Throttle and Prop OEM. 2700ish total time. Time to replace... Quote

Then they switched again in 1971 to a S/N with a 2-digit prefix indicating the model followed by a 4-digit number. Quote

As I recall (off the top of my head) my cables are solid steal threaded on the end. Perhaps the older Mooneys used twisted cable? I could see those wearing out. In fact I had that happen while landing an Aeronca. The twisted cable snapped inside a tube the prevented inspection. -Robert Quote
Hank Posted February 5, 2015 Report Posted February 5, 2015 My cables from 1970 are solid wire centers. How do you define "older Mooneys"? Quote

carusoam Posted February 5, 2015 Report Posted February 5, 2015 My O got a new cable two years ago...something about the design of the '94 cable... That makes it an Older Mooney... Quote
N601RX Posted February 5, 2015 Report Posted February 5, 2015 I'm pretty sure the new cable I just purchased from Mooney is a twisted cable. I'll look and see. Quote
HRM Posted February 5, 2015 Report Posted February 5, 2015 Isn't the McFarlane made cable done under owner manufactured? Also, what does Maxwell charge to do the replacement? I will bet that's an ethereal figure! Quote
isaacpr7 Posted February 5, 2015 Author Report Posted February 5, 2015 Isn't the McFarlane made cable done under owner manufactured? Also, what does Maxwell charge to do the replacement? I will bet that's an ethereal figure! Look at the figures I wrote above. I already did all the footwork. SWT was tge lowest bidder. They order it through Mooney, who orders it from McFarlane; however, because it goes through Mooney it is FAA-PMA approved. Quote

ryoder Posted February 6, 2015 Report Posted February 6, 2015 Do these come with new knobs? I kind of want three new ones with knobs. Quote

BorealOne Posted February 7, 2015 Report Posted February 7, 2015 My O got a new cable two years ago...something about the design of the '94 cable... That makes it an Older Mooney... Best regards, -a- my O got a new cable a few years back as well, after failing in flight. Made for a bit of excitement. Sent from my iPhone using Tapatalk Quote
triple8s Posted February 7, 2015 Report Posted February 7, 2015 When a throttle cable fails would it still go open but maybe not close?? I'm just curious, as to what one might expect. Quote
isaacpr7 Posted February 7, 2015 Author Report Posted February 7, 2015 When a throttle cable fails would it still go open but maybe not close?? I'm just curious, as to what one might expect. It will most likely fail at the fully closed position because it happens when you pull on the knob. My first instinct was to put the throttle rod back and push it in but then I realized that I would have placed it in the full open position (depending how far I pushed it in). When I removed the cable and inspected where it broke, I noticed that it was right at the base where the wire meets the swiveling rod closest to the knob. While the rod was in the chamber it stopped swiveling but while removed, it swiveled just fine. I suspect pilots who flew the aircraft in the past tried to twist the knob as if it was a vernier knob and the twisted wire that was not turning properly began to fray. Quote
RobertGary1 Posted February 7, 2015 Report Posted February 7, 2015 Ah, I wonder if the limited serial numbers is because it onky applies to the push throttle. Not the quadrant we have in the F. Quote
BigTex Posted February 9, 2015 Report Posted February 9, 2015 I just got off the phone with the following companies: Spruce: Does not carry the part as per the SB LASAR: 540 for the throttle; prop is 376 Maxwell: Prop 570; throttle 485 Southwest Texas Aviation: Prop 368; throttle 332 (10 day lead time because they order it straight from Mooney who is right down the street. He said mooney has the cables made by McFarlane but since it goes through Mooney they will be FAA-PMA approved) I spoke directly with the owner (Russell) who was very helpful. Company number is 800-749-7982. I didn't need to buy the mixture control cable because the SB only requires it for the E and F model. https://www.google.com/url?sa=t&source=web&rct=j&ei=U5nTVKvWF4-MyASY9IKoBA&url=http://www.mooney.com/wp-content/uploads/2014/03/sbm20-174.pdf&ved=0CC4QFjAD&usg=AFQjCNFP3T-p43eypGG5hj_uEc1wok6IFw&sig2=FYE_dh9_VGAuMlFEj5M-tw That's what I did... I ordered the prop cable from SWTA and it was drop shipped from Mooney. When I opened it up I was surprised to see McFarlane made the cable. 1 Quote
isaacpr7 Posted February 20, 2015 Author Report Posted February 20, 2015 Finally got my cables in directly from Mooney I is also nice to have knobs that are properly colored It took and extra week due to WX. Funny to se that Mooney doesn't even bother to take the McFarlane stickers off, lol! I did notice that the prop cable is smooth as butter Quote
