REPLACEMENT AXLES

[LEA]

I have not acquired any confirmation from members as to what are approved replacement axels for the rag winged C170?Has anyone any
information & source for the solid or hollow steel axels approved for the 1948 C170?

If you're using stock or Cleveland six inch wheels, I would immagine any Cessna axle or after market axle designed for the six inch wheel will work. I've never heard of anyone of any authority checking axles for type. Actually, in my opinion stock axles are plenty strong enough unless you're going to install skiis where there is no shock absorbtion provided by pneumatic tires.

I installed 185 Axel's on my 48 and my 54 with the STC for landis skis.

Airframes INC at Big Lake is makeing some also. Not sure if they got them approved yet.

For the most part I think that installing the cessna P/N axel is a minor alteration. How ever, some FAA folks probably don't agree.

Blueldr I have a friend who lost a ragwing due to a broken axle with standard wheels so I might be concerned if I had the original axles. Breaking an axle is a good way to destroy a wonderful classic. Bill K

I didn't know you were looking for info. Here's a copy of a recent response to the same inquiry. gh

Well,.....do you know the story behind the axles? You can read all about it at the forum discussions, http://www.cessna170.org/ and using the search routine for "solid axles".... but the short story is:
1. You don't have to switch to solids at all if you don't want to. Your IA is giving good advice,...but it's not a requirement.
2. The solids are also known as "ski axles". The original Cessna ski axle were solid aluminum. They are less likely to crack than the original, hollow, aluminum ones. A crack is difficult to detect in the originals, and it usually occurs at a machine-mark inside the axle near it's base. When a hollow aluminum axle cracks, it will eventually break rather suddenly, usually with expensive/damaging results.
3. There were two types of hollow aluminum axles, neither any better than the other.
4. While the solid aluminum axle is usually sufficient to solve the problem, another solution is a hollow steel axle. Those hollow steel axles are approved substitutes if genuine Cessna, and a company in Alaska is now obtaining approval for their hollow steel axles on the 170. Airframes, Inc.
( http://www.supercubs.com/parts.html ) has recently applied for approval for their PN AF1441003-1 hollow steel axles to be installed on 170's. Their price is also $325 ea., and is likely the same axle Spruce is offering. (They supply Spruce. It's important to know that although Spruce advertises the axles are approved for 170's,...they are not. That catalog claim is in error and Spruce will admit it if called. Airframes Inc was notified by me of this, and that's why they are applying for approval. So if you buy that axle, you might wish to procure it directly from Airframes Inc in order to also recieve the approval paperwork. Make certain your IA understands this.)
