Jim is right, the McCauleys are great. But from my experience working on props, the Hartzell has the edge. For a couple reasons:1 The C214 is non oil filled, so the greese used during assembly is all the greese the bearings get till the next time it goes to a propshop. An the hub has a breather pin, which it has to have, but it lets condensation in. An that's what scrapes those bearings the bearings during overhaul. Corrosion, pitting, rust. That prop has 4 bearings @$500ea x 4. Reason #2, Is the back of the hub. For some reason where the pitch change rod comes through the hub, it wears out faster than normal, an allows engine oil to bypass the Oring an it fills the hub with engine oil , which will end up coming out around the blade socket Oring. The fix is a steel repair sleeve an some machine work....$
Hartzells have there issues as well. If you do not greese a Hartzell properly it will vomit greese down the blade. But I have noticed that the 2 an 3 blade Hartzell propellers seem to make it through the overhaul process with less high dollar parts having to be installed.
If you take care of any prop as stated by the manufacture recommendation, all propellers do pretty well as far as holding up pretty well during overhaul. Being most all are on Part:91 GA aircraft, the operator does not have to comply with the 6 yrs or 2000hrs. Like with a Part :135 operator......
I don't work for Hartzell by the way. Just been my experience dealing with props for yrs.
