Keith:
Google: Monoject 412 or check ebay and you will be the exact little plast
ic syringe I use. They are tough, cheap and it fits snugly into the gear
hoses, I snipped off a bit of the tip to make the hole bigger. I take
off the up and down hose NOT at the cylinder but at the wheel well bulkh
ead at the fittings there, I do this because its hard to get to the fittin
gs on the sides of the cylinders and also because when you inject the side
that the piston is at that end you can't really get much oil in there and
it comes squirting back out. I take off just one hose at a time as well.
I also marked them up and down so it is easier not to screw the pooch.
If you inject at the bulkhead and shove it down the hose it works better.
Once I inject it I pull the syringe plunger back and push it back in a
few times to make sure I get the oil down the hose so it doesn't come squ
irting back out. Its really just trial and error to get the hang of it so
you don't get a hairdo in MMO!
In fact after one or two strokes I pull the plunger out of the end to rele
ase any pressure. For some odd reason my girl don't like the MMO slicked
back look or the smell. I told her it was way cheaper than Brillcream but
she ain't buying it.
I made little covers out of brass with tubes that cover the gear and flap
valve ports, then a hose runs down and out the bottom of the aircraft.
With as much MMO that is running in the system it will mist into the cock
pit and my backseater is a priss. But a nice rag doubled up and wrapped
around and zip tied to each will also do the trick. Just have to change
it every now and again or it will start dripping oil on your flight suit
pant leg!
I really think this has helped the system throughout, and I have seen a fe
w air lines corrode through especially at low points, with the oil in ther
e that probably will not happen again. It also keeps the system very clean
, being a carrier for all the crap it blows it out.
Hope this helps, any more questions let me know.

OK........
TGB, I really enjoy reading your posts but in this case, I'm sure I'm not
the
only one on this list thinking wtf is he talking about.
Injecting oil into gear cylinders with a syringe? I have an "idea" what yo
u are
talking about but a picture is worth a 1000 words.
(I once had to inject some farm animals I owned with antibiotics and let's
just
say it wasn't pretty)
"gear and flap valve shields and hoses that vent the oil mist on cycling
overboard. "
not a clue on this one...I'm guessing this is some custom made mod.
Regards,
Keith

Guys,
Read the manual, it goes into detail as to where to inject the oil, how much
and what kind. Be VERY cautious about over oiling as it will wash the high
pressure grease out of the actuators. This will cause premature failure due
to wear inside of the actuator cyl.
Someone much smarter than me once said when asked "what is the best thing I
can do for my airplane to increase its performance? His reply was to go
fill up the gas tank and go fly, bring it back and fill the gas tank again
and go fly...........in short practice and experience are the best things
you can have to get the most out of your aircraft. This applies to systems
knowledge as well, fill up your coffee cup and go READ your manuals, fill it
up again and READ some more. The list is great, don't get me wrong, but
advice when given is sometimes questionable. The knowledge put forth in the
9 available manuals are the accumulation of many years of experience, the
manuals are a gold mine of facts if you just take the time to read them.
Also, and maybe of equal importance, during this time of increased fuel, and
maint costs, knowing your aircraft's systems and the correct
maint procedures will save you big dollars in the long run. As the Yuan
continues to edge closer to the US dollar parts cost will continue
to escalate. The news papers in Beijing warn of another possible
"adjustment" in the next 60 days due to pressure from the Obama regime.
I'll get off my soap box now.
Fly safe.

Gesus,
Do yall really think I am stabbing a needle through the hose? I am doing
just as Pappy eludes, removing the hoses from the fittings!
Also my AC had less than 500 hrs on it when I rebuilt the cylinders, the
grease was pretty much all gone, hard and not doing a thing at that point
. I am sure you have all seen dried out Chinese grease! So unless you are
taking them apart every 200 or 300 hrs and re-greasing them as the Chines
e ground crews probably did then the grease is gone.

Walt, I don't doubt that at all. There are many uses for a lot of things.
My QUESTION is simply how he went about it. Injecting it through the rubbe
r seal
seems to be the logical answer. Generally I don't assume anything I know
little
about and injecting Nanchangs would fit into that categogy.

One of the items I got years ago in the tool kit that came with a Wilga I
had (back in the days when the factory included lots of tools and spares)
was a strange looking item. Obviously a pump of some sort, looked kinda like
an old insecticide sprayer without the tank, but with a curved tube, oh,
about 1/2" dia., 18" long or so, nozzle with an array of annular holes at
the end. Say what? Looked it up in the IPC and it was a tool for injecting
oil into cylinders for pre-oiling. Not a bad idea if your airplane has been
sitting for a while or after OH before first start. Clever dudes, them
commies, tho I'm sure us Americanos have done likewise back in the day...
