| Subject: | When to service the propeller? |
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 its 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 its 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 its otherwise unobtanium from the popular
aircraft parts stores.
