My RV-10 has the standard Hartzell 2-blade constant speed prop, purchased new. To this point, I've done nothing but lubricate and inspect it annually, as well as file out nicks. I know Hartzell says 6 years for an overhaul, but given limited use (550 hours total time) and the fact that it's always hangared, that seemed excessively conservative. It's also not leaking any oil (still looks like new inside the spinner). However, I'm now approaching 10 years, so curious to hear what people recommend. Thanks!

Since it’s experimental, you can send it to the prop shop to be disassembled and inspected. If there is little wear, you can have them reassemble with new seals and grease. “Pack and Seal”
If it’s worn beyond limits, an overhaul is in the works. But a pack and seal is a middle of the road option for low time props.

I should have added this to my previous message. Some of those seals have a limited shelf life (rubber or synthetics). So they need to be replaced on a schedule once they begin to reach the end of their useful life.

Rob,
You're not alone. I am overdue on my Hartzell also. Nearly 15 years.
But, I did have mine re-sealed a few years ago. I am sure that your
prop will still be functioning fine a while from now, but, I'd say
plan on a 10 year at least.
I've had mine off a few times for various reasons. Inside the
crank cavity into the prop hub, you've almost certainly got a lot of
gray paste build-up that happens over time. I've cleaned mine
out whenever the prop has been off. This winter I plan to get
the prop overhauled, and it will be interesting to hear how it
goes. I agree that 6 years and 550 hours would seem pretty short.
To me it's like how Lycoming recommends an engine rebuild in 12 years
or 2000 hours. But, there still is a point where an overhaul is due
and I think I'm there. I intended to do it when I replaced the engine
this summer, but this wasn't a good year for it $$$.
I have heard overhauls run $2500, but the place near me charges
$3000. Would be nice to hear what kinds of quotes other people have
gotten, and where they recommend.

I had mine (2009 prop with 700 hrs) overhauled a few months ago at Palm Beach Aircraft Propeller, for $2845 + tax.
The seals in it where in pretty bad shape, it was covering my windshield with grease after every flight. A pretty good sign that it needed some TLC.
Btw, Hartzell recommends a new grease now, so if you do get an overhaul, grab a couple of tubes from the prop shop, as it’s otherwise unobtanium from the popular aircraft parts stores.

The main issue with props (assuming no bad nicks, etc.) is the life of
the seals for the blades. It isn't just that they may start seeping oil.
The more serious issue is their allowing moisture under the seal at the
hub grooves.
You really don't want to have an overhaul done unless the blade has been
filed enough to need reprofiling. An overhaul absolutely requires
removal of a thin layer of aluminum, so that a prop's life can only take
3, maybe 4 overhauls. Even on certified planes an inspect and reseal is
perfectly legal.
I too believe than hangaring greatly increases prop life, except in
corrosive/humid environments.

As for the grease in the prop, you should use whatever the prop shop
installed when it was last reassembled, and there should be a sticker
identifying that grease. Most until recent years used Aeroshell 6.

On that note,I read recently that hartzell started using a new grease not long ago. So if you have a new prop or get an overhaul or reseal, make sure to verify the type of grease because you may need to order that special type of grease from there on.

I was surprised with that as well when I had my prop serviced recently. The shop included a tube of the new grease. I have yet to find a source for the new grease other than a prop shop.
Anyone have a solution for stopping the grease from breaking down and leaking from the gun during hot weather? With just six pumps per condition inspection, it would be nice to use a tube on more than one inspection.

I had that happen to me once where the grease broke down and the thin more liquid
portion separated out and leaked out. Made me real irritated.
I *think* it may be due to storing the grease in the gun under pressure, with that
spring pressing against the grease. You don't see it happen with fresh tubes
sitting on shelves, as far as I've seen. So I pull the springs back all the way when
I'm not using the gun. It may be even better to just remove the tube, but I hate
it when the gun doesn't want to prime again.
Does anyone know if pneumatic grease guns don't use springs, and release pressure
completely when not being used? Or maybe the new lithium electric ones? I would
be willing to spend $150 on a grease gun that would fully release pressure on my
grease tube, and always prime well for me.

On that note,I read recently that hartzell started using a new grease not long ago. So if you have a new prop or get an overhaul or reseal, make sure to verify the type of grease because you may need to order that special type of grease from there on.

In Texas, we just keep the grease in the hangar fridge. 🤣. Next to the cold beer.

I had that happen to me once where the grease broke down and the thin more liquid
portion separated out and leaked out. Made me real irritated.
I *think* it may be due to storing the grease in the gun under pressure, with that
spring pressing against the grease. You don't see it happen with fresh tubes
sitting on shelves, as far as I've seen. So I pull the springs back all the way when
I'm not using the gun. It may be even better to just remove the tube, but I hate
it when the gun doesn't want to prime again.
Does anyone know if pneumatic grease guns don't use springs, and release pressure
completely when not being used? Or maybe the new lithium electric ones? I would
be willing to spend $150 on a grease gun that would fully release pressure on my
grease tube, and always prime well for me.

I too had an oily liquid run out from a grease gun with Aeroshell 6 on a warm summer day. I cannot recall if I had stored it with the spring pulled back, or not. I did note that you can mix Aeroshell 6 with 5, if you placard the plane not to be operated in temperatures below some number that I forget. Also, like everyone else, I did a cursory search for the new recommended grease, and could not find any retail source. I did find that it cannot be mixed with Aeroshell. BTW, the cautions not to mix incompatible greases should be taken seriously. I still recall Alaskan Airlines loosing an MD80 just offshore from LAX after they had mixed greases on the horizontal stabilizer jack screw.

Here’s a photo of the new grease Hartzell is now using. It appears that it’s only available through Hartzell authorized service centers. The shop I used wanted $20~$25 per tube.
It would be nice if one of the major retailers would start stocking. I suspect it may take some time for them to begin aware of the change and demand to warrant stocking.
If anyone finds alternate sources, please let the list know.

The manufacturer describes is as follows: (interesting that they list it as a wheel bearing grease)
The newest high-temperature range grease for longer wheel bearing lifeDESCRIPTION
NYCO GREASE GN 3058 is a white lithium complex thickened synthetic grease designed to operate in salty and humid environment in a very wide temperature range going from -54°C to +175°C.APPLICATIONS- Wheels
- Landing gears
- Heavy loaded systems
MAIN BENEFITS- High load carrying capabilities,
- Outstanding resistance to water washout and to high temperatures,
- Very good protection against corrosion even in the presence of salt water.

On my grease gun, I can pull the T handle all the way back, rotate the
handle (takes some trial and error) to find the T handle orientation
where the handle stays pulled out. This keeps the grease from being
under constant spring pressure, which helps prevent the oil from
separating from the wax (on Aeroshell 6).
BTW, Aeroshell now extends the shelf life of Aeroshell 6 if unopened and
stored at constant temp:

On that note,I read recently that hartzell started using a new grease
not long ago. So if you have a new prop or get an overhaul or reseal,
make sure to verify the type of grease because you may need to order
that special type of grease from there on.
