My "new" old one decided to crack into two pieces, tearing the backing plate in the process.

Lemme know if you have or know of a set for sale, or sitting there from a Lyc upgrade.

Thanks,

Gump

Gump,

Is that a six bolt or an eight bolt flange? 7653, or 8042?

-DP

I think it's the 8 bolt. "B" engine, 7653 prop. I'll be down at the hangar later today and take a look.

Gump

Wag Aero had the best pricing on new PMA'd options as of a few years ago.

I have a backing plate, Gump. I have the spinner too but it probably isn't in any better shape than your old one. It cracked after an overzealous mechanic tightened the screws down with a power drill. When I took it off I promptly dropped it on the hanger floor putting a big dent in the nose. So I doubt if my spinner can be repaired.

The backing plate, however, is fine. Only problem is that I'm nowhere near it and it will be at least three or four weeks before I get there.

If you don't find what you need before then... or if you find a spinner without a backing plate... let me know and when I get back to my hangar I'll get it out for you.

Mine was for the 8-bolt, DM76/53 prop on a C-145.

Thanks KG, I may take you up on the offer. Still checking my usual sources.

Prop is the 8 bolt, but it's a Sensenich 7453, I coulda sworn it was a 76". No wonder it's so f**king gutless up here. According to the TCDS the McCauley goes to 76", the Sensenich max's at 74".

Gump

Gump, I'm in kinda the same shape to help you, I have a backing plate and a spinner, it was on a Swift, Maybe it will speed up your Cessna
Any way I won't be home for another 2-4 weeks. If you still need it I'll send it your way? Only question I have is I don't know if it has 6 or 8 bolts??
They are burried in a box in the Hangar at 63S so really don't have anyone to go dig it out!

Thanks George!


If anyone has a McCauley 1C172/MDM 7652, 53, or 55 gathering dust, lemme know.

I'd go for the 8042 but... Ain't nobody with an STC for a C172, just the C170's. And after my battle trying to get the GarAero tailwheel approved ("We just don't know how it'd be possible to allow on a converted C712, if this was Alaska it'd be easy but we can't down here"), I'm not wasting my time with the Feds again.

Gump

I may have that prop for ya. Percentage of proceeds will go to BCP if I do.

Yep, looks like I have that in 7653. No indication that it was ever repitched, but can't swear to that. PM me for photos if interested. I even have a prop shipping carton.

I looked for a spinner in my junk today.... Unfortunately no dice on an 8 bolt.... There is an old 8 bolt prop hanging on the wall.... Will have to ask the old man who owns it...

Brian

Anyone here with personal experience with O-300's and difference in pulling ability between the McCauley 76 and Sensenich 74?

p.s.

I've got a spinner and backplate for you too. The spinner was removed due to the start of a small crack. Don't know if it's repairable, but the backplate should be fine.

Terms are, I'll donate shipping, and when you get it, you come up with a fair offer and donate that amount to BCP.

p.p.s. I always thought a 170 looked good without a spinner anyway.

-DP

I'll PM ya and go over details.

Guess the question is also, is a spinner/backing plate required?

My impression is no, it's not required. At least not on a 170B/ O-300D. Knew of one operating for quite a while without one, and probably not bootlegged under the circumstances.

If you PM me, include your email. It'll be easier to send photos.
