Gyro Fitting Installation Procedure - Piper Dakota Maintenance Manual

GYRO FITTING INSTALLATION PROCEDURE (EDO-AIRE)
The use of Teflon tape on fitting threads is recommended. Install Teflon tape as follows:
Permit no oil, grease, pipe compound, or any foreign material to
enter ports prior to installation of fittings. Make sure that all air
lines are clean and free of foreign particles 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 and
shorten gyro life. Any evidence of the use of thread lube will
create a WARRANTY VOID CONDITION.
l. Carefully lay Teflon tape on fitting threads allowing one thread to be visible from end of fitting. Hold
in place and wrap in dircction of threads so tape will remain tight when fitting is installed.
2. Apply sufficient tension while winding to ensure 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.
4. Press tape well into threads.
Be careful not to exceed torque requirements as noted on decal
located on cover of gyro.
5. Screw fitting into port. (Refer to chart 9105 for torque specifications and manufacturer's address
