I too would service it and fly it. Then if it starts to sling grease, I would consider a reseal. Just to clarify your service memory, you do NOT pump grease until it comes out.. that’s a sure way to over service it. The procedure for tractor props (as opposed to pusher props) is to remove the trailing edge grease fittings, clean inside the hub with a piece of safety wire to free up or break up any hardened grease, then grease the ones at the leading edge by pumping in ONE ounce or stop short of one ounce if it comes out the other side. You do NOT keep pumping for it to come out the other side. One ounce is about 6 pumps with a hand operated grease gun.Agree with previous posters
No pics of the blades, but the hub looks in pristine condition.
Were it mine (I shall repeat, mine), I'd service it, e.g. grease it as it says in the manual. If I recall correctly (no time for me to recheck right now) one has to remove 2 of the grease nipples, and apply the stuff to the remaining 2, until it oozes out. A look at what is coming out would decide... lots of air, water, grease and water, darkly coloured grease => IRAN or OH. Blond grease with none of the above, I'd fly it for say 100h (or 1 year) and observe. No grease leaks, I'd probably go to 500h and then send it in for OH. Again, that's only me...
So why did you pump it till it came out clean on the other side? This is not recommended by Hartzell.I pumped til it came out clean on the opposite side. At least 7 times. 1300+ hours. Troublefree.
My Hartzell manual states 6 years. Paid to have it overhauled at 6 years.
My A** is sitting in it 2 miles above the ground. I don’t think it’s a place to save Pennie’s or dollars. Peace of mind.
Just airplane dollars. Gotta expect to pay em to someone.
Lotsa info & opinions on the internet. Misinformation???
Pumping till it comes out the other side is NOT correct. Look at my post a few up.. I posted the manual with the page number on the procedure. Pumping till it comes out the other side IS misinformation. Although if you only did 7 pumps, at least you didn’t over service it by TOO much..I pumped til it came out clean on the opposite side. At least 7 times. 1300+ hours. Troublefree.

If you are getting “plenty of old grease” out the other side, you aren’t doing it “per the manual”Old aviation proverb: if it ain't broke, don't fix it.
I've had more problems doing preventative service on items than those I waited for signs of an issue. Obviously different functions require different parameters. My Hartzell CS prop is still running well, no leaks after 19 years, 960 hours. I grease every condition inspection per Hartzell instructions. In my case its AeroShell #6, six pumps from a grease gun into the grease fittings at the leading edge. As you'd expect, plenty of old, dirty grease pops out the other side. Finish by cleaning out any residual with a little piece of safety wire. Reinstall the two grease fittings removed for the service and their caps and you're good to go.

That is part of my frustration. The log book only indicated it was overhauled. When I called the shop after I received (and paid for) the prop, they were not interested in reviewing the records to tell me what they found or did.Were there any findings on your prop during overhaul?
I had the same issue with an engine overhaul shop. They did the work in the past. I called to see if I could get a copy of the paperwork, and their single-word response: "No."That is part of my frustration. The log book only indicated it was overhauled.

Absolutely. This is something that should be negotiated and agreed in writing before hand. If you want to go all the way, include financial penalties if they don't actually do it.I'm hoping I can arrange an agreement with the shop before sending my prop in where they'll document fidnings and take before/during/after pics. Even if I have to pay a little extra for that service, it seems worth it to me.
Might be that the IRAN process is sometimes referred to as a "re-seal" when it comes to propellers.Well, my local Hartzell-approved prop shop doesn't advertize IRAN as a service on their website. I talked to them this week, and they're supposed to get back to me about my options. I'll follow up next week, but right now, I'm leaning toward the overhaul. I've read about the fact that there's no way to inspect a CS prop for corrosion. The frequency with which this plane has been flown seems to me to be an ideal way to maximize the opportunity for corrosion (only flown a few hours a year). I've also read about how CS props fail, and it doesn't sound very survivable to me. Not worth the risk IMO.
Records are required of faa repair stations. But they are also used in litigation, so most shops won’t release them without a court order. But the owner of record should have received a copy.I had the same issue with an engine overhaul shop. They did the work in the past. I called to see if I could get a copy of the paperwork, and their single-word response: "No."
Why even have records? What is their purpose if the owner of the aircraft with the engine or prop can't see them?
They’d never sign such a thing.Absolutely. This is something that should be negotiated and agreed in writing before hand. If you want to go all the way, include financial penalties if they don't actually do it.
