779933CC HHYYDDRRAAUULLIICC FFAANN TTEESSTT With COLD temperatures and LOW IDLE, the fan drive pump should be turned OFF. Fan speed will be approximately 100 rpm. Using the "Fan Speed Override" function of ET, perform the following Fan Test: TEST 1: HYDRAULIC FAN OVERRIDE Tools 1) Fan Pump Pressure -- 34450 kPa (5000 psi) gauge or DataView 2) Laptop with ET During the test, fan speed will be overridden to 200, 300, 400, 500, 625, 700 rpm and the solenoid disconnected. Fan Speed Override Procedure: 1) On the ET screen toolbar, click on Diagnostics – Override Parameters 2) Select "Desired Engine Cooling Fan Speed Override" and change the value to the

required rpm (see ET screens below) 3) Using DataView, VIMS or ET, observe the Fan Speeds

779933CC HHYYDDRRAAUULLIICC FFAANN TTEESSTT

Run the engine at LOW IDLE and HIGH IDLE. Using DataView, VIMS or the ET "793C Fan Test" group and a pressure gauge, record the data into the chart. NOTE: When accelerating from LOW IDLE to HIGH IDLE, the fan drive pressure will spike to start the fan rotation. The spike pressure may be the pump High Pressure Cut-off setting of 27000 ± 345 kPa (3920 ± 50 psi) at sea level. The high pressure cut-off valve setting must be set lower at higher altitudes. If the fan drive pump solenoid is disconnected and the engine is run at high idle, the fan would overspeed if the high pressure cut-off valve setting is too high.

TEST 2: 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 the hydraulic fan speed to 625 rpm, raise the engine speed to HIGH IDLE and record the pump pressure and fan speeds. We now know what pressure is required to rotate the fans at 625 rpm at the current altitude. For example, at our current altitude it required approximately 16675 kPa (2420 psi) to rotate the fans at 625 rpm. Pump cut-off pressure should be set a minimum of 2070 kPa (300 psi) above the pressure required to maintain maximum fan speed (625 rpm) with the solenoid unplugged. This will vary with the elevation above sea level. So, at this altitude we should set the pump cut-off pressure to a minimum of 18740 kPa (2720 psi). 1) Install the 5P0048 cover plate at the pump discharge port. 2) Operate the truck at LOW IDLE. The pump should be at the cut-off pressure. 3) 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.

TEST 3: HYDRAULIC FAN PUMP AND MOTOR EFFICIENCY Tools 1) Fan Pump Pressure -- 34450 kPa (5000 psi) gauge or DataView 2) Laptop with ET 3) Fan Motor Port Cover Plate (5P0048) x 2 4) Cover Plate Seal (1P3704) x 2 optional 1) Bolt (8T4910) x 8 -- M12 x 1.75 x 60mm 2) Washer (8T4223) x 8 3) Cover (7I7133) x 2 Pump and Motor Efficiency Test Procedure: 1) Install two 5P0048 port cover plates in the Left Fan Motor supply and return ports to

completely block the Left Fan Motor (or at the manifold block between the two fan motors). Blocking the flow of oil to one of the motors will isolate all of the pump flow to one motor.

2) Unplug the pump solenoid and operate the truck at LOW IDLE. 3) Remove the cover plates from the Left Fan Motor and install them in the Right Fan Motor.

Repeat the above low idle check. If the pump and motor both have acceptable volumetric efficiencies, the fan speed should be a minimum of 510 rpm. If both fan speeds are about the same, but the fan speeds are too low, then the pump may have a problem supplying the required flow. If only one fan speed is too low, then the slow fan motor may be failing.

Pump Compensator Valve Pressure Test: Put a 34450 kPa (5000 psi) gauge on the pressure tap at the bottom of the left steering accumulator In order to use the 785C pump controller as a pressure compensator, the low-pressure standby adjustment screw (screw furthest from pump body) must be turned all the way in. This will block the margin spool from moving and allow the high-pressure cutoff spool to control the pump outlet pressure. Pump low-pressure standby is not used on the 785C Trucks. Start the engine and leave it at Low Idle. As the accumulators fill, the pressure of the oil through the pump outlet increases. The pump supply pressure will increase until the pressure of the oil in the pump compensator valve is high enough to overcome the spring force on the compensator (high pressure cutoff) spool. The spool then moves and opens the passage to the minimum angle actuator piston. This movement occurs when the outlet oil pressure is approximately 17580 ± 345 kPa (2550 ± 50 psi). The pressure setting can be adjusted with the high-pressure cutoff adjustment screw (screw closest to pump body). Backup Relief Valve Pressure Test: The back-up relief valve must be adjusted only on a test bench. The pressure setting of the back-up relief valve can be changed by adjusting the spring force that keeps the relief valve seated (closed). To change the relief valve setting, remove the protective cap and turn the adjustment screw clockwise to increase or counterclockwise to decrease the pressure setting. One revolution of the setscrew will change the pressure setting 3800 kPa (550 psi). A functional test of the back-up relief valve can be performed on the machine by installing a manual hydraulic pump at the location of the Auxiliary Power Unit (APU) connector and installing blocker plates to prevent oil from flowing to the accumulators. See the service manual for more detailed information. Crossover Relief Valve Pressure Test: Put two 34450 kPa (5000 psi) gauges on the pressure taps on the crossover relief valve housing on the left frame rail in the engine compartment. The crossover relief valve housing contains two pressure taps where steering system pressure can be measured. One tap shows pressure during a left turn and the other tap shows pressure during a right turn. To check the steering system pressure, turn the steering wheel completely in either direction. Operate the engine at LOW IDLE. Continue to turn the steering wheel after the wheels have stopped and the pressure will increase to the pump compensator valve setting. Check the steering pressure while turning in both directions. The pump compensator valve setting should be observed on the gauge in both directions. If the pressure readings are different, one of the crossover relief valve settings is probably incorrect. A misadjusted valve must be removed and readjusted on a test bench.

Oil level __________________________________ Oil Viscosity ______________________________ Air/Water in Oil? ___________________________ Oil Filter Examination _______________________ 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 change this 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 slight adjustment 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 hoist output must be in HOLD when changing 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. Time to charge system: seconds
