propeller inspection

[rotorman]

I'm in the process of changing out my engine.  The propeller shop informed me that I has some worn out parts that were due to the propeller hub running dry of grease. I had never seen any signs that it was sling grease. The shop also said they recommend an inspection every 6 years. This recommendation came as news to me.

If you have a Hartzell propeller, it should be greased every annual.

Was there a question to go along with your post?

Really sorry to hear this.  What prop do you have and how long had it been since last IRAN/OH... hours/years.  Was it a hub that’s supposed to be greased periodically?

My McCauley 3-blade just came back from its third overhaul.  It’s 30 years old.  Double the cost of last time, right under 5 amu.

If you need a prop shop: http://www.nwpropeller.com/  was recommended to me, and convenient to you as you drive between Bend and Seattle.  (KPLU, Puyallup).  I got good help from them remotely, and ended up not needing to go in (never charged).

1) You didn't see any grease leave the prop...

2) Did you see any grease go in the prop?
 

See if Mr. Stallings is around for propellor insight.... @Cody Stallings

+1 for NW Propeller. Dick Jacob and crew are great. He’s one of the few shops around that still do the big Hamilton Standard props. He overhauled the props on the museum DC-3. He did a reseal on my McCauley (he talked me out of a more expensive overhaul and saved me a lot of money and blade life).

My McCauley prop has 3000 hours since new, and two reseals but still going good.

Skip do you know if they do dynamic balance there as well?

Im trying to find a good place that’s not too far.

Yes, the do.

If it’s a McCauley they will do that over time.

they may leak just a little grease, an it never really turns into a giant grease leak to make you worry, that’s because there isn’t much grease in them to begin with.

 

wanna keep an eyes on a grease filled prop, once you notice a slight leak it’s time to do something about it to keep the cost down

It's a McCauley 2 blade. No way to grease it. I guess you have to remove it and send it to the prop shop for the inspection. I don't know of anyone who does this every 6 years.
