MALFUNCTION

TEST OR INSPECTION

CORRECTIVE ACTION

4.

ENGINE CRANKS TOO

SLOW TO START.

1.

Check to see if battery cable connections are

clean and tight, and battery water is up to

correct level (WP 0085 00).

Use outside power source

(WP 0027 00) or tow start

(WP 0065 00) the carrier. If the

cause of slow cranking is not

obvious, have unit maintenance

troubleshoot the electrical system.

2.

If temp erature is colder th an

-

25 F (32 C)

check to see if engine disconnect lever is

engaged (WP 0026 00).

CAUTION

Never try to move the engine disconnect

lever when the engine is running. Do

not leave engine disconnected more than

10 minutes. Damage to the transfer

gearcase can result.

Disengage the engine disconnect

lever (WP 0026 00).

If engine still cranks too slowly,

record fault on DA Form 2404

and notify unit maintenance.

5.

ENGINE LABORS, RUNS

ROUGH, STALLS, OR

DOES NOT PUT OUT

FULL POWER.

1.

Check to see if engine is getting enough air.

Check air cleaner restriction

indicator (WP 0004 00). If

indicator shows only red in the

window, notify unit maintenance.

2.

Check to see if there is water in the fuel.

Drain primary and secondary fuel

filters (WP 0090 00).

3.

High elevation operation.

The carrier will normally lose

power at high elevations

(mountain passes or high

plateaus). If carrier runs rough or

has a power loss, push air control

valve in (WP 0028 00) to draw

cooler air from rear compartment

and increase horsepower.

If carrier runs rough or without

much power, notify unit

maintenance.

6.

ENGINE OVERHEATS.

1.

Check to see if all power plant access panels

are in place and mounting clamps are tight.

CAUTION

Driving carrier with an overheated

engine can damage engine. When

ENGINE COOLANT TEMPERATURE

GAUGE indicates above 230 F(110 C),

stop carrier and run engine at 1000–1200

RPM until coolant temperature drops

below 230 F(110 C).

Install panels (WP 0048 00 and

WP 0049 00).
