I've not had an issue with zerk fittings on my Hartzell with standard
grease gun hose. However, be certain to remove the second zerk from the
same end of the hub(you should have 2 on each end, with one on each end
removed.) If you do not do this, you will push grease through the seals
and start your prop hub leaking. Also be certain you are using the same
grease that the hub has been serviced with in the past. There is
supposed to be a sticker on the hub as to which grease to use...often
Aeroshell #6.

Kelly,
I have done everything as you have listed....maybe a fitting is plugged
or the new gun is defective?
I am using Mobil 28 which is compatible with all Shell grease....6&7. Shell
has been used in the past but I like the testing data on Mobil 28. I also
use Exxon Elite oils and in 100 hrs I have added 1 pint between changes.
Looks like I may be buying a better quality gun if cleaning the zerk fittings
doesn't work.
Thanks, Tom in Ohio

While I would try another gun, I advise strongly against using a
different brand grease unless the hub is torn down, inspected and
resealed. "compatible" is one thing in a gear leg or similar, and
entirely different in a prop hub with relatively large quantity of
grease that is going to be mixed for a long period of time. Hartzell
advises against mixing grease in any way. Your prop is not the place to
be trying a new brand.

Not familiar with Mobil 28 grease. I do know that there is a TEMPERATURE co
nstraint for AeroShell 7 when used with the Hartzell prop. You need to plac
ard the panel that operation is not permitted below -40 outside air tempera
ture. My Hartzell was shipped with AeroShell 6 but the West Coast prop sh
op that did the overhaul used AeroShell 7. AeroShell 7 is fine for the flyi
ng that I do on the "LEFT" Coast but would want the AeroShell 6 if I lived
back in Pennsylvania were I grew up and learned to fly.

My Hartzell manual says that 6 and 7 can be mixed but if you do=2C there is
a do NOT OPERATE below -40 OAT limitation that goes with the AeroShell 7 g
rease. AeroShell 6 does not have that limitation.
I agree that I would not change brands of grease without a reseal. I would
only use the grease that Hartzell lists in their manual.

Is your Hartzell prop new from the factory? It should not be a problem
if new---NOT a used prop wherein someone could have changed the
fittings. Mine has worked perfectly for 7 years.
Possibly someone changed the fittings, if yours is not new from
Hartzell, OR there is a problem with your grease gun not being a
standard configuration common to automotive grease guns.
Be sure you remove the opposite-side grease fitting as described in
Kelly's response below.

What a great set of responses.
I can find nothing t disagree with so far. These are all great pieces
of information and come from the manufacturer.
Let me add one small bit of gossip. When my prop was overhauled the
shop put AS 7 in it. When I asked why, since it had come with 6. His
response; "it don't leak."
So there is a trade off between 6 and 7. My assumption is that 6 is
"thinner" and 7 is "thicker". I am very happy with the -40 degree
restriction. I wouldn't want to try starting the Lyc or the pilot at
that temp, much less fly. I do cycle the prop before take off, in
the winter, to make sure it is not sluggish.

| Subject: | Circuit To Combine Mag P-Lead For RPM Measurements |
Has anyone found a device or circuit to pick off the output from the P leads on
the left and right mags for feeding to an RPM measuring device such as the GRT
EIS-4000? The EIS-4000 only has a single RPM input. The installation manual
suggests installing a SPDT switch between the left/right mags and then to the
input on the EIS-4000 for manually switching between the mags during drop testing.
But that's pretty hoekey. Seems like someone should have come up with
a simple prioritized switching circuit that would, say, always read the left
mag p lead unless there wasn't a signal, then read the right mag P lead output.
In my "spare time" maybe I'll make one if there isn't something already out
there like this.
I thought that once upon a time I saw an electronic gizmo you could screw into
the standard tack drive that would give an electronic output. Anyone have a line
on this device and whether its compatible with the GRT EIS?
Thanks!!

Matt-
The Vision Microsystems did it on the VM1000 is they have a simple
inductive pickup (their P/N 3010005 for the Slick mags) that screws into the vent
cap location on the right mag and picks up the movement of the rotor. It's
a little pricey though ($380).

mags during drop testing. But that's pretty hoekey. Seems like someone
should have come up with a simple prioritized switching circuit that would,
say, always read the left mag p lead unless there wasn't a signal, then read
the right mag P lead output. In my "spare time" maybe I'll make one if

The end of the grease gun is adjustable for a tighter or looser fit,
right? Maybe its too loose on the fitting.
I stuck with the aeroshell 6, as was originally used when assembled.

Yes, I do remember that thread. In fact, I have those pickups installed, but I'm
not getting any reading on the EIS-4000 with either one of them. I'm using
the vent hole closest to the engine block. Have you successfully interfaced
them to the EIS-4000?

Is your Hartzell prop new from the factory? It should not be a problem
if new---NOT a used prop wherein someone could have changed the
fittings. Mine has worked perfectly for 7 years.
Possibly someone changed the fittings, if yours is not new from
Hartzell, OR there is a problem with your grease gun not being a
standard configuration common to automotive grease guns.
Be sure you remove the opposite-side grease fitting as described in
Kelly's response below.

While I would try another gun, I advise strongly against using a
different brand grease unless the hub is torn down, inspected and
resealed. "compatible" is one thing in a gear leg or similar, and
entirely different in a prop hub with relatively large quantity of
grease that is going to be mixed for a long period of time. Hartzell
advises against mixing grease in any way. Your prop is not the place to
be trying a new brand.

Shell has been used in the past but I like the testing data on Mobil 28. I also

The problem is you need to purge the Shell that is already in the hub.
There is NOT a good way to do that. Mixing is taking a big risk.

| Subject: | Re: Circuit To Combine Mag P-Lead For RPM Measurements |
I sent my EIS 4000 back to Grand Rapids for updating to the latest
firmware while my aircraft was down for paint. Looking at the new manual
that came back with the updated unit, I see that it now has two rpm
inputs, and it looks like it will automatically switch between them to
pick the one that has a signal at any given time. This seems to be
intended to solve exactly your problem.
Open questions, which are maybe answered in the manual, but I forgot it
at work, so I can't check now:
1. what happens if the two ignition systems that are connected to the
two inputs require different pulse/revolution numbers? I don't recall
seeing a way to define different pulse/revolution numbers for the two
rpm inputs.
2. which rpm input does it use when both have a signal?
I recommend you contact GRT. Perhaps you simply need to get your EIS
updated. They turn them around pretty quickly, so you won't lose much time.

| Subject: | First Engine Start - Lycoming IO-390 Purrrrrzzz! |
Dear Listers,
The first start on the new Lycoming IO-390 from AeroSport went great. No
major issues to speak of. The exhaust bolts on the left rear cylinder were
a little bit loose, the hall-effect RPM sensors in the mags didn't seem to
work, and there was a small fuel leak coming from the fittings on one of
the fuel pressure transducers. Other than that, WOW! What a powerful
engine! In the video, I only got to about 1/3 throttle and it felt like it
wanted to jump off the ground! Really strong sounding and the 4-into-4
Vetterman exhaust really gives the motor a throaty sound. All of the
controls (throttle, mixture, and prop) worked as expected. Cycling the
prop pitch worked great. Fuel flow was good and I tested feeds from both
the left and right tanks. The left and right mags also checked out good as
did the kill switch. AeroSport bench ran the engine for 11.5 hours at my
request. This should get me well past the critical breakin period. The
ease at which it started attests to that as well.
Wow! That's all I've got to say! I can hardly wait to point this baby down
the runway and "get 'er done"!
In addition to the usual still-picture fair I normally attached to my log
entries, I've now added YouTube videos as well! And - they're in full
1080p HDTV resolution too! When the YouTube player comes up, in the lower
right hand corner it will say "360p" by default. Select the highest
setting that works on your computer without stuttering (480p/720p/1080p).
The HDTV versions are amazing clear. I can hardly wait to get some
air-to-air shots.
The cameras are Sony HDR-CX550V and HDR-XR550V units and sport 64GB of flash
and a 240GB hard drive respectively. They record in full 1080 HD and Dolby
digital 5.1 surround sound. I have the HDR-CX550V mounted on a head rest
mount on the back of the pilot's seat and the HDR-XR550V is used for tripod
or hand held action capture. The head rest mount is a little too low to
see over my shoulder and I've got an extension ordered that should lift it
well over the obstruction. I edited the various clips down using Adobe
Premiere CS4, which is very nice, btw.

I had the pleasure of being present at N998RV's startup and can attest to
the healthy bark of the mighty IO-390. Matt's metal work and interior are
nothing short of outstanding. She's going to be one sweet ride. If Matt
goes ahead with the paint he has planned, he will not be able to sneak into
any airport in the country.
