How do you add the air tool oil, just let it get sucked in the pump inlet??

Roger,
No need to reinvent the wheel, I have the larger stainless steel filter
bodies all made up with new filters and desiccant. Having said that you
will have to find the end caps to screw on the stainless body. I am sure
that there are many laying around out there as I have sold a bunch of the
stock new Chinese filters in the past. Installing a second filter would be
very easy and would remove any unwanted water...........even in Florida.
If anyone reading this has any useable end caps for the larger CJ6 filters
please let me know so we can help out some of the guys who are stuck with
the smaller, nearly useless little filter. In my opinion this is the number
one most important part of your pneumatic system maintenance and if you
don't maintain it properly you will be fighting other problems down stream
for years to come. Once you contaminate the air system it is very hard to
get 100% clean again. Drain your slobber pot after every flight, check your
water filter at least twice a year, more often if you live in a humid area.
I carry all the inner filters and desiccant in stock if you need them.
A;ways yakin,
Doug Sapp

Doug,
Would you have pics of what the diferent filters look like? I'd like to make
sure that I have the proper system installed in mine.

Ernie,
Its a no brainer. The small on is exactly that about 3 inches long, when
you try to open it up to service it will find that only one end threads off.
The small one contains NO desiccant, only filters and screens. The large
high capacity filter is over 6 inches long and both ends come off for
servicing. The filter that is shown on page 20-1 in the Airframe Accessory
Overhaul manual is the small filter. Hope this helps. When you
check/service your filter check the pitting (the tolerances are listed in
the overhaul manual. Remember this unit runs at very high pressure and if
it ever decided to fail it could take out your oil system and do other
unspeakable things in your engine compartment. This unit is often
overlooked during inspections. The last pitted one we tested blew up at 900
psi. Yes, that is over the operating pressures, but just how much longer
would it have lasted?? Its simply not worth the chance. I think there is a
good reason why the Chinese have called out such low tolerances for pitting
on the inner walls of the stock alu. filter body. The new stainless steel
body simply does away with the corrosion problem, best thing since sliced
bread!!
Always yakin,
Doug

I have the long one, if its the one mounted on the upper starboard side of
the firewall. Is it pressurized all the time or is there a check valve
upstream of the dessicant, in other words do I need to depressurize the air
system before I remove it from the system?
Thanks
Ernie

--> Yak-List message posted by: ByronMFox@aol.com
At the EAA Golden West Flyin in Marysville, CA, this past weekend, the
airshow announcer asked Hal Morley for a written description of our CJs so that
he
could describe our craft to the crowd as we took off for our formation passes.
Oops! We had nothing prepared, so Hal, in his fine hand, cobbled together a
brief write-up. While this sufficed, it would seem appropriate to have
something "OFFICIAL" to give to such people. Has anyone written such a document?
(I'll volunteer if not.) It would be convenient to be able to download it from
the All Red Star and YPA sites.

Ernie,
From your hesitation about it's location and type I will assume that you
have never had it apart to service it. It is most likely the root of all
present and past problems. Because of where you live I will wager that if
you have never serviced it you will find that it is a oozing pile of goo
which is pushing all that crap on down stream. I would recommend that you
de-pressurize your system, inspect the filter and replace or service as
necessary. If you find deep pits I have the stainless filter bodies, if you
just need desiccant and filters I have them too. If you find that it has
been pushing gunk on down the line you need to flush everything out if you
want to ever get back to the point to where everything is operating
reliably. I have never personally had to flush one out but I am told that
once the valves and all rubber parts are removed one should start with
solvent, rinsing till clean, then final rinse with alcohol. Blow dry. Then
clean and replace the valves and rubber parts. Lightly oil all the rubber
parts during re assembly. This is a ton of work, most all of which could
have been avoided. In China these aircraft are swarmed over each day by a
horde of little fellows who service such things as this and make sure all is
ready for the fearless aviator. Here in the states we have to be both guys,
and wear both hats. Good luck,
Let me know if you need any help.
Always yakin,
Doug

Doug,
Does this super filter of yours work on 52's? I have just the short one on
the firewall below the popoff valve.

Well, I remember when I first got on this list I was a little concerned
about the green goo that came out of the snot valve after each flight, but
since it was called a snot valve I assumed that the sinus infected looking
mess was normal. But after several of your ominous cautions of the system ,
I had to admit that I had never dis-assembled the unit and I had no first
hand knowledge of its condition. And now that you have succesfully scared
the bejesus out of me, I am going to be forced to look into the matter more
closely. I have not had any air problems to date, but I guess I'm not going
to wait and I will check it out this week since I'm grounded with an ear
infection. I figured if my head has gotten all gunked up with goo then its
possible that my air system has also. Even though I had done a bore scope
inspection of my air bottle this past annual (March) and the bottle was bone
dry and there was no rust, I am going to err on the side of caution amd heed
the advice of my esteemed colleages and check it out.
Thanks
Ernie

Ernie;
The filter is mounted on the upper PORT side of the firewall (that is left
for all you southerners). It is pressurized when the system is under charge
and there is a non-return check valve. You can remove it without
depressurizing the system.

Walt

All:
I've depended on the "kindness of strangers" and the
round-engine, wrong-direction gang in my neighborhood
too long and I've run out of tool-borrowing chits.
If anyone has an extra russian M-14P engine tool-kit
that they wouldn't mind selling, I'd give it a caring
home.
Regards,
Harry Hirschman
PS: Please send your response directly to me ("reply"
sends it to the whole list)

Doug;
The small filter is only about 2" in length. It has proven to be a real
problem with intergrannular corrosion. The repair limit shown in the O/H
Manual is very conservative when one considers the actual strength of the
assembly.
But there is a reason for that conservatism. The depth of intergrannular
corrosion is, for all practical purposes, impossible to measure since it
follows the grain boundries and has exactly the same effect as a crack
The generally accepted rule for rework is to remove all visible evidence of
corrosion and then remove another .020" (0.5mm) for insurance. At that point
you may consider whether there is adequate material remaining or the unit is
scrap.
Turns out that the small filter, because of it's very small volume, can
tolerate a quite drastic re-bore (well in excess of the manual limit) and
still pass a 75 ATM (1200psi) hydrostatic test. Just confirmed that today
with the unit from my aircraft (which I will scrap even though it met the
test). I bored it out approx. .080" on the dia. and further locally reworked
corrosion up to another .030" on the RADIUS.
The reason this drastically reworked unit passed where a lessor corroded but
unreworked one would likely fail is that the stress was evenly distributed
rather than being concentrated at the grain boundry cracks.
Not totally useless info since it will allow me to repair and return to
service units that may be over the manual limit. Though I will set my limit
far less than the one described above.
Woudn't have to go to all this trouble if my good buddy with the nice
stainless steel filters also had caps for them so us peons with the old,
small, filters could convert.
Cheers;
Walt
