I’ve got three McCauley propellers sitting here in the hangar and I’m weighing up my options. I can overhaul the McCauley D3A34C402/90DFA-10 with a new hub to fit the aircraft. That will cost me 4800stg if my blades are good. The other option I have is overhaul the threaded/obsolete design McCauley which is the D3A32C90/82NC-2. Prop shops immediately back away when you mention these props. We got one quote for 7800stg – which priced in 3 No. Ferrules at 1200stg each. Has anyone here overhauled a threaded prop? Is anyone here operating one and can comment on the more frequent oil leaks I read about?

I can break down these three props, and sell them as cores as Plan B and buy a Hartzell kit either in that event.
Thanks Peter,
I posted the question on backcountrypilot and got a similar response. Thing is these props were fitted on aircraft made in 1970’s or earlier, like the C210/C206/F33C etc. So they are not stone age and certainly something I will watch out for in future. My plan is to break down the threaded prop in a propshop and test the individual components so I can sell them on if they are serviceable. Then build up the other prop I have as a D3A34C401/90DFA-10 which will be the one that offers the most performance.
