Yeah, I think there’s about 4 different published legit ways to put this together. That SB is from 1968 though and my parts catalog is newer. It shows 2 different ways depending on year/type. I talked to the parts people at Lasar since the steering horn came from there in 2003. They are sending me all new hardware, bushing, etc. They are sending a bolt, castle nut, cotter pin to go there, so I think it will be what you guys were talking about.

So reading m20-169, it shows this bolt and nylon insert nut (circled below).The parts manual seems to show a different bolt and nut with cotter pin. Mine looks just like tge sb, but was installed in 2003. Which one is right?

I like my lean find as well. Mostly for the reasons @0TreeLemur said, but also because my gami spread is close enough that my last to peak (richest) can be different based on conditions. If I cruise down low at high mp and without ram air, maybe it’s #2, up real high with ram air on, likely it’s 3. One other nice thing about LF is it allows the jpi data analysis program to quickly analyze that point and you can see if things are changing. Maybe a plug Or timing issue slowly developing? In general, you’re right that it’s unnecessary if you just watch the temps closely and have an idea how it will end, but extra toys/options are always nice, no?

@EricJknows this but I quoted him to expound on what he said, Oil coolers get gunked up and bent fins after a while too, so maybe cool less effectively when it’s hot out, but when it’s really cold, you can still see low oil temps and higher pressure. Heres the thing, as a pilot, you’ll notice the pressure is directly related to your rpm and oil temp. High rpm, cold temp = high pressure (like initial takeoff). Low rpm, high oil temp =low pressure (like idle taxi after landing). It is easy to see yellow range high and low in these conditions but the engine be working fine.

I agree, I was talking about the 22 bolt, not circled. Isn’t the ipc showing it go the other way?

while waiting for someone to post one put together correctly, I found this picture on MS from another airplane. Isnt the bolt (not the circled ones) in backwards?!

Dumb question, but will one of you guys with a “vintage” airplane post a picture of the back of your nose truss/steering horn assembly please? Thanks.

Looks like I’ve got some work to do. Glad it stayed on 19 years!

There’s a firefighting tfr near astoria that is showing on g1000 with xm. How about your system?

I believe you guys, and parts manual has a cotter pin. Check out my picture below. This has been on there since 2003 when “new lasar steering horn (old style) installed” No pin.

Do you happen to remember a couple specifics.. I have the Mooney part number of the bushing that the AN4-21 bolt goes through (left side of my picture), but I can't find a standard part number for it. Any idea where you got it? (914020-031). The parts manual calls out a cotter pin as part of that bolt, bushing, washer assembly, Mine doesn't currently seem to have one, just a nylon locking nut? Do you remember if you did? If so, was it a castle nut and drilled AN4-21 instead of undrilled? As Doc mentioned, there are several SBs and upgrades, so I'm trying to figure out which version I have and what parts I have before taking it all apart. It could be a problem to figure that out and/or to find the parts.

For such a “simple” job, I’ve seen a lot of comments that include blood, cursing and contortion.

Yep, it looked like it moved in each of the areas you said. I’m going to have to prep my mechanic for this… not sure how long (if ever) it’s been since he’s taken apart one of these. Thanks.

I played with my nose truss this morning before flying. With the nose solidly on the ground, I’ve circled where there appears to be some play. The video link shows me moving around that part while the nose wheel isn’t moving. Anyone know if this is probably just bushings and shims? I plan to look closer up on jacks at the upcoming annual.

It’s really easy except when it’s not. I definitely recommend going back first after pulling the aft pin. Then forward and off. Ive had mine on and off four times. Three times they came off with minimal blood/cursing. Three times they went back on ok too. Once they were pretty much stuck like yours after putting them back on. Took forever to get them back off, checked, carefully put back and they magically worked. No idea what had stuck them. Go slow, be patient, expect a challenge more difficult than it should be (which isn’t much but can be frustrating). Try not to bleed on your carpet too much.

So #4 was about Carson speed for you? If so, it seems like it’s in a reasonable place?

Some of them are welded into the tubes (gear i think?) and they are a little harder to do without involving mooney… we had a thread around here in the last year about that. The ones that are removable are standard part as suggested above.

Wow, @DonMuncy , those look amazing!

So what’s the wait time on them? Getting new or OH lyc cylinders has been 6+ months at many shops…

I currently have an stec 30a which is 2 axis, no trim. It annunciates required trim similarly. If you just want to use the airplane for long vfr cross country and the occasional approach, it’s fine without the auto trim. Thats how I use my airplane, and it’s just fine to help out in occasional ifr / imc. If you use it in imc a lot and fly a reasonable number of approaches and use it in busy airspace, I’d get the auto trim and give yourself one less thing to worry about.

Thanks. That did it. I made the mistake of looking under “nose wheel assembly” and “rigging nose wheel steering”. Those parts aren’t in those sections of my parts manual. Based on your attachment, I looked under “flight controls, rudder and nose wheel steering”, and there it was! My diagram isn’t as good as yours, so thank you. Nice meeting you today Skip! Drew

Do any of you guys know exactly where I can find information and diagrams on the steering “shims or bushings”? My nose wheel is starting to get a decent amount of play in it and id like to read about it and possibly order any parts before the annual in January. I’m hoping it is something less than a new steering horn/truss. My maintenance manual has no info on play in the steering. Parts manual shows several places with shims and bushings but isn’t specific?

Speed is pretty dependent on load too. If you’re 1 person and 30 gal of fuel that’s 5kts or more difference than gross. I only get 150ktas on my F ROP, ~6500’, cool temps, and light weight.

I’m just saying this because you didn’t draw the distinction above and it can become dangerous, I know you know this pitfall, but you’ve got to be careful saying it… if you load an approach (say on radar vectors) and then enter direct to the FAF (as you say “just go Direct to an approach waypoint”), your hsi will center up and give you steering direct to the faf. You will also have distance to the faf. It can very easily look like you’re “established on the approach” when in fact you’re way off of the course into the faf. Depending on clearance, I have seen people descend to faf altitude because it looks very much like they are established. Using vtf or activating the leg into the faf are much better.

Yes, I’d agree with that. You do have to “activate” it somehow if you want the automated switching to vloc, but yes, there are different ways to “activate”.
