Hello All, I’m at the tail end of my nightmare annual (I hope) where I’ve essentially brought a plane back from the scrapyard at this point. Engine is due back from overhaul in mid to late October and trying to get the final pieces in place. 1968 M20G (680021 Serial) The MX is letting me source parts to try to save a little bit of money, but I’m struggling to find alternator brackets. The fall-back plan is to buy the plane power, but an overhauled ALY-8520 is about $800 so I’d rather take that route if I can. The alternator that was on the plane was a CarQuest Alternator which the MX won’t put back on the plane (pictured). All of the manuals I’ve looked at show the generator, not the alternator. It should be the same as the M20C (Lycoming O-360-A1D). The alternator overhaul shop I was buying an alternator from said they have a bin full of brackets but they would need dimensions and a photo to see if they can find the correct brackets in the bin. Does anyone know where the correct brackets can be found, or can anyone share their bracket images and dimensions? (Or have an alternator and brackets they want to sell? Can be a core. (also on the hunt for an overhauled oil cooler…) As always, thank you in advance!

After looking through the Parker/Cleveland manual it seems like the Beechcraft planes use different variants of the 40-87, from my understanding we can’t use the 40-87C

I had the same question!

Would you happen to have any wheels (nose or main) in there by any chance? Looking for my M20G, should be the same as C-K with serials 670001. Thank you!

Hello, My M20G has found itself in need of a new set of wheels during its annual. The A&P found corrosion on the wheels and said they all needed to be replaced. As such, I’m looking for a 40-87 nose wheel (cannot find used options anywhere online) and 2x of the 40-86 main gear wheels. If anyone has a lead on some, it would be greatly appreciated. Looking to purchase together or separately. (I did see 40-86 options on eBay). My A&P called Cleveland and clarified that it does need to be 40-87, Variants such as 40-87C are not compatible based on his conversation. Thank you in advance!

Thanks for the help all, its getting flown to another location on Monday and I'll have them give their opinion, but I'm providing the Heim bearings and theyre going to install them and swing the gear to get the door closure setup properly. I'll have them look at the hinges as well. I was able to find the heim bearings on ebay as they were available right away, but Lasar did have them as well (as well as the 550017-005). To clarify, I did use the term "ferry" more loosely than I should have, but the CFI does insist on flying it there with the gear down. Its going to a shop he recomended, so I'll see what they have to say. I appreciate the help of everyone here to get me flying again, and also save me $1000-2000. My CFI is fairly young, but he has 1600 hours and as the student I'm going to let him do what he thinks is proper (as long as its not costing me an arm and a leg when it doesnt need to). In regards to the existing Heim bearings, the wear is on all four bearings and its the ball being loose in the sockets. My Statesman is mostly original, and the last pilot that owned it was a bit of a cowboy in the fact that he'd just get in and go as opposed to giving it thorough inspections. I'm learning as well so this has been very helpful. I most definitely dont think the bushings are there based on my memory of seeing it so I'm ordering new bushings as well (550017-005)

Would love to hear what you find. I have an M20G due for annual in May. I’m at 06C (Schaumburg, IL) and am trying to find a shop for an annual. Holiday Airways here at 06C is supposed to open a shop in the next month or two, and I believe their lead mechanic is a long-time Mooney expert, but I’ll believe it when I see it. Until then I’m still looking for a shop for annual also

The slop is MOSTLY from the rod ends. All 4 have pretty bad wear in my opinion. There is some slop in the hinges too without a doubt, but I’d say it’s 85% rod ends, 15% hinges. Transparently there was a bolt and nut that held one of the linkage brackets to the door that was loose, and that caused the door to have a lot of play, that’s been rectified, but it brought the attention to the rod ends. I think once the rod ends come in (got them ordered) I’ll have them installed by an A&P and get their opinion. Another operator at our base is supposed to open a shop in the next month that has a Mooney expert as their lead mechanic, so I’m counting down the days until that happens

Just wanted to say thank you for the detailed response. I had actually looked this up in the parts catalog, but was confused by the need for the whole assembly as opposed to just the bearings/rod ends. I saw that both were offered but couldn’t quite narrow down what I was looking for as the G is not very popular and the lasar site was not very helpful. Really appreciate you taking the time to spell things out

Unfortunately I’m a student pilot and Midwest winter weather means that I’ve gotten 10 flights in out of a scheduled 30-40 so far. My CFI says he’ll fly it somewhere nearby with the gear down if I want to go to another shop since he knows the FBO will take forever (he works for their flight school, so he knows how behind they are since all his flight school planes are down for maintenance with them). I’m fine paying them for the work that does actually need to get done, but it sounds like myself and everyone is in agreement that just the hiem bearings need to be swapped and not the entire assembly. The shop says they cost $750 each and need to be fully swapped. In 1.5 weeks since they looked at it, they haven’t given me a quote or part numbers to order so I had been sitting here twiddling my thumbs wondering what to do next. Thanks to everyone for the guidance

Unfortunately I really doubt the A&P here will sign off on anything not done by them. Feels like a cash grab (but it could be for liability which I also understand). He already told me that he would have to put it up on jacks and swing the gear to check the door closure as well if they were to do the work, so I don’t think I’m getting a quick sign off. They’re doing a full engine swap on an M20K that bit the dust here, and all 3 of the FBO’s planes are down for maintenance, so I’m pretty low on the totem pole of profitability and priority with this job for them

Thank you both. I’ll see if I can have my CFI ferry it elsewhere and have just the Hiem rod ends replaced Thanks again!

Hello all, my CFI recently recommended we ground my 1968 M20G until we can get the nose gear door linkages replaced. I have been waiting a week for the FBO mechanic to get me a quote, but I’d like to get the parts on order as it’s going to be weeks before he can get to it from the sounds of it. The part is shown in the attached image, I’d need them for both nose gear doors as both are sloppy. It seems to me that the slop is all in the ball joints, but they’re recommending the whole assembly get replaced on both doors Can anyone assist with the part numbers?1968 M20G. Thank you in advance!

Shot you a message, would love to hear more! I just saw this C go up for sale, and I thought the owner also said he just put it up for sale. Would love to know if that’s not the case. Congrats on the F as well!

This is fantastic, I believe there was a gentleman here at 06C that used to service Mooney’s (Gene I believe was his name), but he’s since retired. Having someone at DKB is great!
