| Subject: | Re: Hartzell prop lubrication |
I don't know, I think some of the doubters should test the theory and
just pump it full until it comes out...
I did that once a long time ago (maybe 2007 or 8), thinking that my
understanding was better than the manuals logic.
Eventually, I ended up having grease sling out of the hub, and
I had the prop re-sealed, which cost I think $860.
So, those that doubt the manual can test the theory and see if
they have the same problem. That way I won't be alone in the
boat. If it happens to a few dozen of us who didn't believe
the manual, then we'll know that the manual is smarter, right?
But, if nobody else has the problem, then we can know that our
vast pool of a couple dozen anecdotal cases are better than
the stuff Hartzel tells us. :)
I know me, I'm going to follow it to the letter from now on.

I had some grease or something on my windshield last year after my annual and going
to Oshkosh. Stopped at the hartzell booth to ask them their thoughts. They
were very
Responsive and concerned. I was then introduced to Scott Foster.
Talked to him he got my contact info
And called me the week after Oshkosh. They wanted to inspect my prop. Scott came
up the next week and we removed the spinner
Looked for leaks and determined a zerk fitting was a little loose. And leaking.
Tighten it up
Then we discussed the amount of grease. I had told him I pumped until
Some came out. He said that 2-3 pumps no more. I pumped way more than that. The
good news my prop was ok and he
Said everything looked great for almost 500 hrs. But he did say no more than 2
pumps and told me not to grease mine at the next annual.
Great customer service and Scott is great.
Then I took him for a ride in the RV-10. He was impressed with the performance
and loved the RV-10.
He was drinking the the RV-10 koolaid and loving it.

Done the theory, no leakage thus far!
However, I appreciate this thread and will stick to the manual moving
forward. I always worried that I didnt have enough grease, seems that that
is normal and not to worry about!
Thx

So that leads to the question, why does their manual state six pumps? If that's
too much and they are recommending something different, shouldn't Hartzell
update the procedure in the manual?
Then we have the issue of does my gun pump the same volume as somebody else's?
It seems like it's still using a bit of magic and luck, since there is no effective
method to measure the actual volume of grease until you pump too much and
it oozes out the back.

Tim must have been watching me do my prop
Only I have not had mine resealed yet. Just slings a bit of grease now and then,
especially first flight or two after the ACI..

It's a real WAG on my part, but I'm guessing that the volume of grease
isn't anywhere near critical. The WAG part: if there's sufficient grease
to coat the blade seal to keep it flexible and offer some lubrication to
the hub ... it's sufficient.
