If any of you folks attending All Red Star at Porterville feels the need for speed...well
I have a contest proposal I'd like to see tried out so it can be replicated
at other events. Basically it's a timed from a pass over the runway,
out about 5 to 6 NM, around a "pylon" which is an easy to see road intersection
where a "judge" can check for pylon cuts and then back to the airport to stop
the clock.
Sounds simple enough but I have to tell you that some practice is required to get
a good line around the pylon without eating up too much time and bleeding off
a lot of energy. Holding a precise heading and altitude helps shave off seconds
as well.
This isn't just for CJ's; Yaks, RV's and spammers could try this too. Each run
will be over in 5 minutes so several airplanes could run the course during the
late afternoon or early morning when other events aren't running and the bumps
are smoother.
Let me know, off 'list, I have a proposed course, over flat land, free from towers,
and a scenario on how this could work. If a fun-type contest is the result,
we could replicate at other events and maybe even award "Speedy" patches to
class winners??

I think you have an M-14 with a two blade V-530 hub correct? If so...
Depends on exactly what you mean by hub seals. The ones on the prop
blades are there to keep the grease in. If there is OIL coming out of
THOSE prop blade flanges, it is not a bad Hub Blade seal that is the
problem. It's one of the OTHER ones.
If we are talking OIL, there are usually three areas of concern.
1. The large and small o'ring seals for the hub piston (you take the
front hub cover off to get at these)
2. The oil control tube crush washer. This is the PIPE that screws
into the front of the engine that the oil goes through to get to the hub
and control the prop. This has a crush washer on the front that leaks
and ends up coming out the prop area.
3. The shaft seal on the reduction gearbox...that is NOT easy to
change, but does not usually go bad unless you're doing serious acro.
You're going to have to determine exactly where the oil is coming from.
That has been my experience... Others better versed probably have more
accurate advice. I am by no means a prop expert.

Remove the prop dome and piston assembly. If there is oil inside the
hub, the inner seal on the piston is bad (possibly incorrectly installed
too) OR the seal behind the oil tube is bad or the tube is not fully
tightened. Most likely it's the inner seal on the piston if there is
oil pooling inside the hub. If the piston outer seal is leaking, there
will be oil on the inside of the "skull cap" dome. As Mark says, check
the front seal on the nose case to see if there is evidence of oil
around the prop hub/flange shaft.
