UC-61K (F24) Tail fairing

Post by coxargus »

'Folks - Happy new year to all.

Does anyone have a copy of Drawing or photos of PN 411051 (figure 24 item 3 in the UC61K parts manual) for the fairing under the rear of the tail they could e-mail me. Mine have seen some 'Modifications!' and some unprofessional repairs in the distant past. I would like to get them as correct as possible if I can.
The drawing is not on the CD.
Any help is greatly appreciated.

Prop Hub material UC 61K Argus III

Post by Ji?í Horák »

'Hi everyone,

I've just found a cracks on the front prop hub plate on my Ranger powered UC 61K. We are able to manufacture new one. Could somebody send me a type of material and heat treatment required? (we found that HRD is 88, which is pretty ordinary steel)

Thanks very much indeed,

'HI FRANK,
I have a pretty original stuff. I will try to make a pics this week or at the end of the month. My KK 502 S/N 1120 is very original - in fact like it left the factory (I'm restoring it now) I have this fairing for sure.
Cheers,

'Hi Terry,
Thanks very much. It is Warner 6 bolt hub for sure. Will find the P/N once I will get to the Hanger. Found the cracks only on plater. The rest of the hub is fine.

Hi everyone,



I've just found a cracks on the front prop hub plate on
my Ranger powered UC 61K. We are able to manufacture new
one. Could somebody send me a type of material and heat
treatment required? (we found that HRD is 88, which is
pretty ordinary steel)



Thanks very much indeed,

Assuming the weather doesn't stop me from going to work tonight, I've got the AN specs for hubs, nuts and spaces on my computer at work. No problem looking up the info.

Hi Terry,
Thanks very much. It is Warner 6 bolt hub for sure. Will find the P/N once I will get to the Hanger. Found the cracks only on plater. The rest of the hub is fine.

Hi everyone,



I've just found a cracks on the front prop hub plate on
my Ranger powered UC 61K. We are able to manufacture new
one. Could somebody send me a type of material and heat
treatment required? (we found that HRD is 88, which is
pretty ordinary steel)



Thanks very much indeed,

'The AN5017 spec is in the group files, but it doesn't give a material call out.  It refers to a procurement spec for that.

Hi everyone,



I've just found a cracks on the front prop hub plate on
my Ranger powered UC 61K. We are able to manufacture new
one. Could somebody send me a type of material and heat
treatment required? (we found that HRD is 88, which is
pretty ordinary steel)



Thanks very much indeed,

Re: Prop Hub material UC 61K Argus III

Post by Hugh Loewenhardt »

'Jiri,
  In lieu of finding the original material for your propeller plate, McMaster Carr Company, in the US, has certified 4130 alloy steel plate, in suitable dimensions, of Rockwell hardness B85, very close to B88 you specified. The 4130 plate can be heat treated to C60.  Also, check out "making an aircraft propeller hub" on YouTube. Good machining information and also a material suggestion which makes sense considering the application for an aircraft propeller clamping, pressure(friction) plate.

  Hi everyone,

I've just found a cracks on the front prop hub plate on my Ranger powered UC 61K. We are able to manufacture new one. Could somebody send me a type of material and heat treatment required? (we found that HRD is 88, which is pretty ordinary steel)

Thanks very much indeed,
