completely drained of air.

2. Disconnect air supply line (2)

from air pressure gauge

adapter (3).

3. Connect air supply line (2) to

test gauge (4).

4. Start engine (TM 9-2320-361-

10) and allow air pressure to

build up to normal operating

pressure.

NOTE

Air pressure gauge on instrument

panel has a maximum pressure

reading of 120 psi. If old governor has

been replaced with new governor, air

pressure may exceed maximum

pressure reading on instrument panel

gauge.

5. Check test gauge (4) reading.

1. If reading is low or zero, check air

supply line (2) for bends, kinks, or

leaks. Repair or replace air supply

line if bent, kinked, or leaking

(TM 9-243).

2. If reading is above 85 psi (586 kPa)

on test gauge (4), replace air

pressure gauge (1) (WP 0094 00).

1. Refer to WP 0014 00, table 1,
