TEST: HYDRAULIC FAN HIGH PRESSURE CUT-OFF

Tools

1) Fan Pump Pressure -- 34450 kPa (5000 psi) gauge or DataView

2) Fan Pump Port Cover Plate (5P0048)

3) Cover Plate Seal (1P3704)

High Pressure Cut-Off Test Procedure:To determine the high pressure cut-off setting at the current altitude, use ET to override thehydraulic fan speed to 817 rpm, raise the engine speed to HIGH IDLE and record the pumppressure and fan speeds. Pump cut-off pressure should be set a minimum of 2070 kPa (300 psi)above the pressure required to maintain maximum fan speed (817 rpm) with the solenoidunplugged. This will vary with the elevation above sea level.1) Install a blocker plate in the line from the makeup valve to the fan motor.2) Disconnect the pump control solenoid.3) Operate the truck at LOW IDLE. The pump should be at the cut-off pressure.4) At sea level, adjust the cut-off pressure to 27000 345 kPa (3920 50 psi). At higher altitudes a

lower cut-off pressure may be desired.

2) Laptop with ET

Pump and Motor Efficiency Test Procedure:

1) Unplug the pump solenoid and operate the truck at LOW IDLE.

If the pump and motor both have acceptable volumetric efficiencies, the fan speed should be a minimum

of 817 rpm.

The hoist system can be enabled or disabled in the Transmission/Chassis ECM using ET. All trucks shipped from the factory

without bodies installed are set at the Hoist Disabled Status. The Hoist Disabled Status is a test mode only and will prevent the

hoist cylinders from accidentally being moved. After the body is installed, enable the Hoist Status for the hoist system to

function properly. Shown below are the three Hoist Statuses.Hoist System Enable Status:

- hoist system is not installed- hoist system is installed and enabled (normal operation)

- hoist system is installed but disabled

Make sure the engine is not running and the truck is not moving. Transmission Output Speed (TOS) needs to be zero to changethis parameter. When the engine is running there is sometimes some jitter on the TOS signal, which could keep the parameter

from changing.

The hoist valve LOWER position is an adjustable parameter in the Transmission/Chassis ECM using ET. The slightadjustment provides a means to compensate for valve differences. The adjustment range is from -5 to +5 with zero as the

default. A negative number will decrease the lower speed and a positive number will increase the lower speed. With the

engine at HIGH IDLE and the hoist output in SNUB, pump output pressure must be less than 1725 kPa (250 psi). The hoistoutput must be in HOLD whenchanging the setting.

AIR COMPRESSOR TEST

To test the air compressor efficiency, lower the air system pressure to 480 kPa (70 psi). Start the engine

and raise the engine speed to HIGH IDLE. When the air system pressure reaches 585 kPa (85 psi),

measure the time that it takes to build system pressure from 585 kPa (85 psi) to 690 kPa (100 psi). The

time to raise the pressure should be 50 seconds or less. If the time recorded is greater than 50 seconds,check for leaks or a restriction in the system. If no leaks or restrictions are found, the air compressor may

have a problem.
