REMOVAL AND REPLACEMENT OF CLUSTER MOUNTED INSTRUMENTS.
A cluster, located on the instrument panel, contains six individual instruments. Removal of these
instruments can be accomplished by the following procedure:
1. Remove the face panel by removing the screws from around the perimeter of the panel.
2. With the face panel removed, the clear plastic cover on the cluster assembly will be exposed. Remove
the cover and cluster by removing the six mounting screws.
3. Remove the connection to the individual instrument to be removed and remove the instrument from
the cluster assembly.
4. Replace the instruments by reversing the removal instructions. Check all mountings and connections
for security.
GYRO FITTING INSTALLATION PROCEDURE (EDO-AIRE).
The use of teflon tape on the fitting threads is recommended and should be installed as follows:
—CAUTION—
Permit no oil, grease, pipe compound or any foreign material to
enter parts prior to installation of fittings. Make sure that all air
lines are clean and free of foreign particles and/or residue before
connecting lines to gyro. DO NOT USE THREAD LUBE ON
FITTINGS OR IN PORTS. The use of thread lube can cause
contamination shortening the life of the gyro and can cause
premature failure. Any evidence of the use of thread lube will
create a WARRANTY VOID CONDITION.
1. Carefully lay teflon tape on the fitting threads allowing one thread to be visible from the end of the
fitting. Hold in place and wrap in the direction of the threads so tape will remain tight when the fitting is
installed.
2. Apply sufficient tension while winding to assure that tape forms into thread grooves (One full wrap
plus 1/2 inch overlap is sufficient).
3. After wrap is complete, maintain tension and tear tape by pulling in direction of wrap. The resulting
ragged end is the key to the tape staying in place.
4. Press tape well into threads.
5. Screw fitting into port being careful not to exceed torque requirements as noted on decal located on
cover of gyro. (Refer to Chart 9105 for specifications and manufacturers address.)
