| Subject: | Re: CJ Canopy Rollers Replacement |
Greg,
You'll need a flat head screw driver, with a thin blade also it's shank can'
t be to large. Also you'll need a special tool to take off the flat notched
nuts on the outside of the canopy. At one point this becomes a two man job
.
In the INSIDE of the cockpit, about where your shoulder would be, you'll fin
d about a 1/4" hole along the canopy rail. This where you will insert the s
crew driver. You have line up the bolt that holes the bearing with that ho
le. The bearing bolt has a very shallow slot for the screw driver and you m
ay have to fiddle with it some to get it to engage.
Meanwhile your partner is out side with the special tool to remove the low p
rofile notched nut. You can make this tool (I did by grinding a pair vice g
ripes) or using a pair of needle nosed pliers.
You'll need to unscrew 3 bolts on each side. When that is done, move the ca
nopy to the rear where you find a slot in rail where you can remove the bear
ing bolt. At this point you can pull the bottom of the canopy out slightly t
o remove the bolts along with the bearing.
Cussing during this process is normal while fiddling.

Yak 52 or CJ6? Very likely you have a bad check valve between the
external air fill port and the pop off valve/pressure relief valve. I
have anovernight test you can do to eliminate some other possibilities.

Air leak:
Check needle and seat in the main air valve, it is std steel and often
rusts. We carry a stainless replacement steel needle if needed.
Air won't build:
Check to make sure that compressor is pumping. Rubber glove over intake is
best initial check.
Check poppet valve, clean seat and check alu crush washers for leaks. We
have a kit that has all the crush washers, poppet spring, and filter if
needed.
Check line between compressor and snot valve for cracks/leaks
Check snot valve needle (is std steel) which has a problem with rust on the
needle, your compressor may be having trouble overcoming the leak.
Filler bleed back of air most likely is a bad check valve.
Best,
Doug

Ken,
My 2 cents.. and just some other comments.
1. Pay attention to what Dennis Savarese says... he has fixed a lot of air leaks.
2. An Ultrasonic Leak Detector is a good idea, but ... if you understand every
single line, valve, pressure regulator, flow regulator, in the entire system,
you can run tests that narrows it down. Enter Dennis.
3. You mentioned your air goes from 6 to 4 in one day. 6 is actually 60 Atmos,
which is about 881 PSI (plus or minus) and this system is supposed to be set
to 50 Atmos, which is about 735 PSI. Leaving it set too high can be why you
are having a hard time removing the external fill line, simply because you've
added about 146 PSI to the recommended pressure. Fix that ASAP. It also puts
too much pressure on seals in the landing gear systems, etc.
4. When you are flying, see if the pressure comes up faster if you leave the landing
gear down, then it does when it is up. If you, you might have a leaking
landing gear actuator. They can leak when up and not down, and vice-versa.
5. Read #1 again. :-) I'm going to stay away from making any further recommendations
simply because Dennis knows the 52 better than me.
Good Luck,
Mark

Hi there...
We have a CJ-6 just imported out of Australia (VH-NNE) that has been flying
with the serial number listed as 2432027.
Inspection of the data plate would indicate that it is actually stamped as
3432027.
Can anyone tell me if 343 is a valid factory ??? code?
It is a 1968 model
Need to ask so that when our Feds look at the data plate they will no doubt
ask all sorts of questions!
Regards, Jay

For what it's worth, I've had a "secret weapon" for air leaks for awhile, an
d I might as well tell the rest of the world...
If you have access to a "freon sniffer", put a little R134 into the system a
nd then charge it up. I guarantee you will be able to find it...those sniffe
rs pick up even the slightest if freon leaks.
Hope that helps someone

If you have access to a "freon sniffer", put a little R134 into the system

I have never put more than a "shot" of it in the system, and then completely
drained the system after the test. I also will tell you that I use only fre
on, not that mixed freon/compressor oil crap you buy at auto stores. That ma
y be what you are referring to "eating up the seals".
I, personally, haven't ever experienced any repercussions with the pure freo
n.

A STRAIGHT HOSE TO THE EXTERNAL AIR FILL PORT, LOOSEN THE LARGE NUT ON THE
HOSE END THAT GOES TO THE TANK AND BLEED THE LINE. FIRST MAKE SURE THE VALVE
ON THE TANK IS CLOSED THOUGH., simply because you've added about 146 PSI to
the recommended pressure. Fix that ASAP. It also puts too much pressure on
seals in the landing gear systems, etc.

CHECK VALVE ON THE INSIDE OF THE FIREWALL, WHICH IS FOR THE EMERGENCY SIDE.
NOT THE MAIN SIDE THAT WAS LEAKING DOWN. I EXPLAINED TO HIM WHERE THE CHECK VALVE

Hi there...
We have a CJ-6 just imported out of Australia (VH-NNE) that has been
flying with the serial number listed as 2432027.
Inspection of the data plate would indicate that it is actually stamped
as 3432027.
Can anyone tell me if 343 is a valid factory ??? code?
It is a 1968 model
Need to ask so that when our Feds look at the data plate they will no
doubt ask all sorts of questions!
