Subject: Pneumatic Instrument Gauge
I'm looking for a Yak-52/Yak-52TW pneumatic air pressure gauge that's
located on both the front/back instrument panel just above the landing
gear handle. I believe it=92s also used in the Yak-50 and other Soviet
Aircraft. The gauge has two needles that monitor the air pressure in
the utility (normal) and emergency pneumatic system. This instrument
(not to confuse the subject) is also referred as a 2M-80K Dual Manometer
on the Instrument Panel Diagram in the Yak Manual.

Thanks for the info,
I should have said my Cj is a 1988 model
Since my post i've had a good look through the parts manuals and It appears something
to do with the gyro compass is mounted up high in the tail just forward
of the rear fin, I think this is what was just mentioned,
A separate post indicated some form of voltage regulation might be mounted between
the cockpits and i'm almost certain there is an inverter mounted there and
an identical one mounted in the tail. My guess would be the one in the tail used
to supply the adf antenna / radio receiver and the one between the cockpits
serves the instruments.
Hopefully I can identify and remove much of this, it weighs one hell of a lot!
(Avgas is too expensive to give it a free ride :) )

Harv.
Mine is a 1988 as well. However, mine has a mechanical voltage regulator behind
the firewall whilst my Buddies (same batch) has an electronic voltage regulator
on the shelf between cockpits which I suspect was an air force installed mod.
I did manage to remove 166lbs of surplus wiring and tube radios including the complete
ADF system. However, I did keep the Magnuson type compass in both panels
which requires that remote system with the little window just before the tail.
It is a very nice feature as you can use it as a bug ... sort of like a very
poor man's RMI. I also kept the inverters and the nice electric DGs
So be careful not to remove something you might still like to have. My electrical
Guru did a great job rewiring and I am running two King 196 VHFs a Garmin TX
and a self enclosed Narco ILS all very nice and of course light weight. Once
the ADF antenna and box is removed you can re-configure. Some folk modify the
ADF box for tool and spare oil storage. Perhaps, a better alternative is to
remove the ADF box's shelf aft and reconfigure as the battery (batteries 2x12v,
modern, sealed, which will fit in the existing box) shelf. That then gives loads
of room for a secure luggage area. This you can ensure is sealed to prevent
FOD making its way back to cables and pulleys and still have a port and starboard
access door as well as access from behind the rear seat. NB, the starboard
access door is smaller than the one on the port side, so plan accordingly.
This then leaves you the large removable panel on the starboard side, not only
can you have the battery(s) there but it might be a good spot for a smoke tank.
Of course this is all CofG and weight and balance dependent. I agree about
not carrying excess weight at today's horrendous fuel prices. Be safe and good
luck. Coop.

Hi Harv;
That is the actual magnetic compass for the Gyro Compass system. On the
very early aircraft like mine it was mounted near the LH wing tip.
Later moved to the better location in the aft fuselage as you described.
If installed (it is a military modification) the solid state voltage
regulator is mounted behind the rear seat either on the shelf or below that
on the front spar. I think Joe Howse was correct that it is on the spar.
You may or may not have that. The normal regulator is on the aft, upper, RH
side of frame #1.
There are two necessary inverters. Refer to my previous post. There is a
third one (for the ADF) located immediately behind the rear seat with all of
the comm radio, radio compass(ADF) and interphone system that you can
totally remove.
You bet it is heavy. With all associated parts and wiring you can remove
approx. 195 lbs. Of course you will later have to install some ballast to
compensate for it.
regards;
Walt

Harv;
I should read before sending rather than after----- Referring to the solid
state voltage regulator I wrote "rear seat". Should have been front seat.
