 Posted: Fri Sep 23, 2016 1:00 pm Post subject: Hartzell prop Overhaul/Inspection |
 |
|
Hi all, thought I would give everyone a heads up wrt when/if you have your constant speed prop overhauled or inspected by a propeller facility. Due to my earlier MT governor failure and engine/prop over speed, I took my prop to Hope Aero near Toronto for a visual inspection. While it was there it was also discovered that one of the prop blade seals was pinched as I was getting a small amount of grease on my RV10 windshield. Hartzell covered this under warranty.
However when Hope Aero re-assembled the front black coloured dome to the hub, it was positioned in a slightly different position. Since the front spinner plate is bolted directly to this black dome, my front spinner/plate screw holes no longer aligned.
So I was faced with a few of options. Return the prop to Hope Aero (not a good one as the prop was torqued and wire tied to the engine), buy a new front plate, or rotate the front plate 90 degrees and re-drill and fasten new #8 nut plates to the new holes. I ended up rotating 90 degrees.......
Bottom line, if you are in this same situation make sure the overhaul facility know the black dome needs to go precisely back in the same position. Kind of a poor design on Vans part IMHO. Wish I had known this beforehand.

I had a similar experience this year but with a different prop shop. Ended up putting a new front plate in as that was far easier and it didn’t add additional weight out there.

Rick,
You are 100% correct, I about tore my hair out trying to figure out why my spinner wouldn't align after an overhaul. You described the issue perfectly. I did the same as you and drilled a new set of holes in the spinner.
After the fact, someone pointed out that I might have been able to slot the four holes in the face of the plate, and rotate it slightly. You'd have to be very precise with the slots, but it might be another option.

Thanks for ruining my day there Rick.
Just picked up my prop.
This is the gift that just keeps on giving.
Edited note: I just spoke to my prop guy and he said that it is impossible for them to mark the position and then put it back exactly there because the dome is set by torque which will always vary enough to offset the screw holes. He said that the notching the holes on the forward brace to allow adjustment is what he recommends.

The "ruined my day" comment was just sarcasm. I'm actually appreciative for Rick for making this post as it was something I hadn't thought about. I notched my plate holes so now I'll be ready when my motor gets back.
