I saw your ad and was wondering, when you say they are solid, are they solid all the way through? There are two axles that came with my 8KCAB project and they're also aluminum. Are all of our Cleveland axles aluminum? I thought they were steel? Thanks in advance!
 
they are solid aluminum, milled 1.5”. Similar to the ones guys replace on cessna‘s when they are doing tundra tire/ski installs. They were originally on my plane prior to rebuild, I put a different heavy duty steel set on that came off scout (also installed double pucks that were a matched set to those axles). I’d have to dig around and figure out manufacture of axles. I’ve also seen heavy duty hollow aluminum axles, but not the best for ski flying in my opinion.

Maybe that's what I have in my parts bin, heavy duty hollow aluminum axles. I had no idea they'd make axles out of anything but steel. Thanks for the explanation!

Scout Axle 8GCBC 3-1549 05-06328 $156.75 - From Aircraft Spruce. Doesn't specify its 1 1/2" but it's different from the rest.

From Alaskan Bush Wheels -

American Champion series 7 and 8
  • Note: American Champion series 7 aircraft require GCBC (Scout) axles to work with Alaskan Bushwheels.
I think what is implied is the Scout has 1 1/2" Aluminum Axles and the rest have 1 1/4"
 
No they are steel. at least when Bellanca owned the type cert. id bet the modern Aca axles are also steel. From what I know about citabria’s 1.5” is standard for spring gear. Maybe 1.25” with oleo, I dunno. You don’t need Aca scout axles for skis/bushwheels, many different types work well or better. My scout axles have the bearing race stop milled into the axle and doesn’t leave a ton of threads for axle nut on Landis 2500’s. the aluminum axles I’m selling work way better for those skis, custom bushings make for easy installs. Many ways to skin this cat

I just went and looked, that is what I've got, aluminum, 1 1/2", with the stop integral to the axle. Scout? the guy i bought the project from also dismantled a Scout at some point. I sold most of those parts but still have a beat up set of wing tips, a pilot static assembly, and I guess these axles. also have a set of those nuts like yours on the axles.thanks for the replies, really appreciate it.
 
Bartman & AK,

On the backside of the axle does it give the Part Number and perhaps stamped with ACA? Usually a black ink stamp.

In talking with Ron (Rainbow) a while back. He suggested that Scouts have always had 1 1/2" Aluminum Axles, right back to day one. As well as the non standard wheels, if you will.

Is it possible some of the Citabrias - 7GCBC have been retrofitted with 1 1/2" Aluminum Axles to accommodate big tires along with wheels & brakes from ABI and others?

https://www.groveaircraft.com/5016.html Can you tell me if your axles differ from Grove's?

Seeing how it's a quiet Sunday Morning. Can I start a Conspiracy Theory? - LOL. Is it possible that Grove mfg the 1 1/2" Aluminum Axles for ACA and when they arrive they are rubber stamped with a part number and ACA. Then they are considered certified? The reason I'm thinking this, is because Grove sells them as experimental and haven't PMA'd them for the Scout.

Bob, any thought's?

Where is this going? I need a set of 1 1/2" Aluminum Axles that are deemed certified for my Scout.

Thanks.

if you don't want AK's solid axles I'd love to sell you my hollow ones as I'm trying to raise money to buy the Grove wheels/brakes/axles for my Decathlon build.

as for your theory, at some point those axles would have to go through a certification process that I would expect to be the same regardless of who is taking credit for their manufacture. Maybe ACA is having Grove manufacture them to ACA's Bellona spec which was certified? or was that what you were saying in the first place? 🤔

Your probably right, I might have a 1 off set currently installed. Imo the best thing a guy could do is use a set of steel axles (Cessna airforms, Cleveland, etc) and do a 337 and field approval. Or pony up and give ACA whatever ungodly amount of money they want. Would go heavy duty if you ever plan to run bushwheels or skis. The Cessna style axles require you to install bushings in the -6 holes if I remember correctly, as there are 2 different size holes in the axle mounts.
 
I hear you.

Any stampings on the backside of the mounting flange?

If we are running a Certified Aircraft, technically the axles should be stamped. If we are under Owner Maintenance or Experimental, different story.

I'm sure the Grove Axles meet or exceed what ACA sells as certified. We never hear of too many axle failures.

Interesting thread.
 
1607887577021.webpBuddy ran these steel airforms axles on gcbc for years and worked awesome until bearing failed. Short of finding old/new scout sock 337 and a field approval works just as well, much stronger than hollow aluminum
 
No they don’t have stamp. Technically you don’t need stamp if you submit ppwk, ia sign off and fed approval. Many parts installed in/on aircraft that way. I can tell you how many different axle, tire, brake configurations I’ve seen. Though I agree that the more markings and documentation makes for easier installs and general understanding of what you have.

Thanks for the info up top. I'm not sure Transport Canada has the same courtesy to accommodate.

Yes, they are expensive from ACA. It would be nice to know if they are hollow or solid? To my way of thinking the ones pictured up top are considered solid. And, hollow on the thread bearing portion at the tip.

My plan is to buy ABI Wheel and Brake Assemblies with 3 through bolts. They are also fitted on the C180 & 185. In order to install Alaskan Bush Wheels as an option in the future.


Thanks!
 
That’s the only way to do it. Airframes makes good components and it’s pma’d from what I understand. Logbook entry and done. If you wanted the best bang for your buck mcfarlane ti axles with the cessna brake configuration would be strongest lightest combo possible. if it is strong enough for a 3300lb 185 running around beating them up, I’d say our little fabric planes should be within the envelope. At least with faa if you have data and can convince them it’s stronger and safe than oem they will play along. Not sure about my eastern neighbors but it would be worth a call to your version of the fsdo. Hopefully I’m not making this convoluted or confusing but there are many other paths than ACA to achieve a better stronger install than hollow aluminum (though I haven’t seen oem failures). Semantics I guess
 
Life is much easier as a super cub owner, turn your head and you bump into a 337/stc. I’ve learned owning citabrias you just gotta think of creative solutions To get where you want.

Agreed! Just look a the STC's on Alaskan Bush Wheel Website for Super Cubs. Amazing.

The other alternative is to buy a Super Cub Experimental Knock Off. One of my favs is the Smith Cub by Nick Smith and his Dad.

Here we go with the purists! LOL...
