Is this an example of an early C180 heavy duty axle, or the standard axle?



Thanks, Ron

If it's steel then yes it is.
There are hollow aluminum axles i think. There are solid aluminum axles. The steel axles are the best the rest can bend or break especially with skis.
There is also a super heavy duty "ski axle" that uses the usual four bolts and two more on each side of the gear leg with a sort of clamp setup.

Excellent! No logbook entry, but I have steel axles that look just like that on my 180B. It also has the NAS allen head heavy duty bolts. Every now and then something works out better than expected.

Thanks!

Great you have the NAS bolts. I'm told they are getting hard to find. Reeves usually stocks them but they could not find the small diameter bolts. I installed the bottom large diameter bolts when installing 29". Does anyone know a good source for them? I have yet to shop around.

Just for reference. I have seen these solid aluminum axles referred to as heavy duty. Maybe they are for a Cessna 150 but steel is best.

Yingling has some of the NAS145 and NAS146 bolts in stock; also the corresponding MS numbers are MS20005 and MS20006. To cross-reference, you need to use a table like this: http://www.gen-aircraft-hardware.com/im ... _intwr.pdf

Also, the PN called out in my Parts Manual don't match what's installed (too long), at least with Cleveland brakes.

HTH, Ron

Hollow aluminum ales were standard, at least on he 120/140 & 170, but most have been replaced with "heavy duty" solid aluminum axles. I've heard the hollow steel axles referred to as "ski axles".
Spruce offers their p/n 05-00481 steel axles (for 180/182/185 & 206) at $365 each. Seems like I recall Dodge, Arframes AK, or McFarlane offering these axles also but a quick google didn't come up with anything.

Hotrod- all those vendors are selling airforms axle. https://www.airforms.biz/index.php?rout ... uct_id=780

They also make a titanium axle.

Ah, Airforms. I kinda remember seeing a press release on those but mis-remembered that it was Airframes Alaska.
