INTERSTAGE AlR-BLEED ACTUATOR. Pneumatic device that mounts on the compressor

housing. Connects mechanically to compressor bleed band. Opens and closes

bleed band on input signal from fuel control.

OIL COOLER. Mounts on interstage air-bleed actuator and by bracket to compressor housing.

Uses fuel flowing through passages surrounding oil paths to absorb heat from the

oil. Connects in fuel system between the fuel control and the in-line fuel filter.

Connects in oil system between the main oil filter and certain major bearing

filters and strainers.

IGNITION EXCITER. Mounts on brackets secured to compressor housing. Connected electrically

to spark igniters by coil and cable assembly. Contains a vibrator transformer

which converts low voltage to high voltage.

IN-LINE FUEL FILTER. Mounts on bracket on inlet housing. Provides final fuel filtering prior to

delivery to the main fuel manifolds. Contains a paper filter element. Provides a

visual indication when it is close to bypassing its element because of clogging.
