Gear Pump Circuits

Basic Hydraulic Troubleshooting

Gear Pump Circuits

Step 1: Test for Pump and Main Relief
Theory

If all functions of a gear pump circuit are malfunctioning, the problem may be poor suction conditions or a
malfunction of the main relief, the first component in the circuit, or the pump.

Test Suction Conditions

1. Verify oil level.

2. Visually inspect the suction lines.
3. Remove suction lines and check for obstruction.

Test Main Relief

Main relief should be connected to the pressure line that comes from the pump. It may be located in the
pump, as an independent relief, or in the first valve of the circuit. To check the relief:

1. Verify the pressure of the main relief.

2. If pressure is not correct, try adjusting the relief.

IMPORTANT: Document the number of turns made to the adjustment in case you need to go
back to the original position.

3. If adjusting the relief does not work, remove, clean, and inspect.
4. Install the relief and test again.
Basic Hydraulic Troubleshooting Technical Supplement
Gear Pump Circuits

Test First Component in the Circuit

The first component in the circuit after the pump may have an internal leak or be obstructed in a way that
effects the entire circuit. Depending on the circuit, this can be evaluated in different ways. Consider
bypassing or inspecting the component.

IMPORTANT: Do not bypass the main relief.

Test Pump

Measure pump flow with a flowmeter and needle valve (such as test kit p/n 259-501). On a good pump,
flow should not decrease more than 70% when the pressure is increased. Sometimes measuring the
speed of a function can approximate flow. See your Ditch Witch repair guide for more information.

NOTICE: Always have a main relief in the circuit to avoid pump failure.

Step 2: Test Valves and Actuators

Theory

If one function is not operating properly, the problem is probably in a valve or actuators (cylinder or motor).

Test Valves

NOTICE: Perform these tests only after you have verified they will not damage components in the
circuit. Before troubleshooting, identify if there are any orifices in the circuit.

• Test electric valves with manual overrides if available.

• Consider switching hoses (re-routing) with another valve to determine if the problem is in the valve or
the actuator.
• For leakage on a valve that has PO checks, exchange checks with another location to determine if the
leakage is due to the PO check.
• For valves with work port relief, exchange reliefs with another location to determine if the relief is
malfunctioning.

Test Actuators

• For leakage in cylinders, perform a cylinder leak test.

• For motor actuators, measure the case flow.
Technical Supplement Basic Hydraulic Troubleshooting
Hydrostatic Circuits

Hydrostatic Circuits
Step 1: Check Charge Pressure
Theory

The charge pressure is low because of:

• oil leaking out of loop

• bad suction conditions
• pump malfunction

Test for Oil Leakage Out of the Loop

1. Measure charge pressure when the unit is malfunctioning.

2. If charge pressure is correct, go to Step 4.
3. If charge pressure is low, oil is probably leaking out of the loop. Look in the following places:
• Flushing valves or hot oil shuttles (Determine if you can cap off the flushing valve for a test. Do not
block case flow or you will cause a failure to the motor). If possible, measure the flushing flow
• Shift valves, brakes, brake valves, gripper valves, or any other valves that us charge pressure
(Determine if you can cap off these functions temporarily to test them)
• Motor leakage into case. Measure case flow, but remember to adjust for hot oil shuttle flow if
necessary. Consider measuring case pressure as an alternate test.

IMPORTANT: Measuring flow is preferred because pressure varies and is not accurate.

• Charge relief valve (either remove and inspect, or replace)

Test Suction Conditions

1. Verify oil level.

2. Visually inspect the suction lines.
3. Remove suction lines and check for obstruction.
Basic Hydraulic Troubleshooting Technical Supplement
Hydrostatic Circuits

Test Pump

The remaining causes for low charge pressure are charge relief, pump leakage, or charge pump
malfunction.

Charge Relief

1. Remove, clean and inspect the charge relief.

2. Re-install and test again.

Pump Leakage or Charge Pump Malfunction

1. Cap and plug the loop lines and all other external lines except the case drain and suction. In this state,
the pump is separated from the circuit.
2. If charge pressure is still low, you can eliminate everything external to the pump.
3. If charge pressure is correct, go to Step 4.

Step 2: Verify Main Pressures

Theory

The hydrostatic circuit is not producing the torque expected.

Test Main Pressure

1. If the pressures seem low, measure the maximum pressures of the main reliefs.
Technical Supplement Basic Hydraulic Troubleshooting
Hydrostatic Circuits

Step 3: Verify Pump and Motor Signal

Theory

The pump or motors are not being given the proper control signal, control pressure, mechanical control, or
the pump is not being turned.

Test Signals

1. Check the linkage, cable, pilot pressure, or electrical signal.

2. If the pump is equipped with manual overrides, use them to check signal.
3. Verify that the pump shaft is turning.
4. If the pump and motors are getting the proper signal and power, go to Step 1.

Step 4: Test for Oil Leakage Across the Loop

Theory

The loop is leaking from one side to the other. In this situation, charge pressure might be correct, but the
loop cannot produce full speed or torque.

Test

Look for ways the oil is leaking from one side of the loop to the other side. Consider the following

• Motor leakage across the loop (Will not show up in case flow. Cap off motor pressure lines.)
• Loop pressure relief valves (Exchange them to test.)
• Tow valve (Verify that it is closed.)
• Neutral valve
• Flushing valve
Basic Hydraulic Troubleshooting Technical Supplement
Load Sense Circuits

Load Sense Circuits

Step 1: Check Pump Differential
Theory

The reason for the malfunction is that the pump differential is wrong.

Test

1. Check the pump differential under the following conditions:

• at standby (not using any functions)
• when using functions that work properly
• when useing functions that are not working properly.
2. If differential wrong in any condition, try to adjust it. If it can’t be adjusted to the proper differential, go to
Step 2.
3. If differential is correct, go to Step 3.

Step 2: Check Pump

Theory

The pump is not operating properly. Possible causes are poor suction conditions or pump malfunction.

Test Suction Conditions

1. Verify oil level.

2. Perform an external visual inspection of the suction lines.
3. Remove suction lines and check for obstruction.

Test Pump

1. Cap off pressure line from pump and connect load sense signal line to pressure line. Pump should go
to compensator setting in this condition.
2. If pump does not go to compensator setting, the pump is malfunctioning.
3. If pump does go to compensator setting, the circuit may have an internal leakage in a valve in the
pressure circuit. To test, reconnect pump to the circuit, and block off valves one by one.
Technical Supplement Basic Hydraulic Troubleshooting
Load Sense Circuits

Step 3: Check Shuttle Circuit

Theory

The shuttle circuit has a leak or blockage that is causing the problem.

Test

1. Functioning some valves in the circuit and identify changes in behavior to determine which shuttles
could be leaking.
2. Cap off parts of the load sense signal circuit.
3. Run a separate independent signal line from the valve to the pump.
4. Identify any orifices in the load sense line and inspect for blockage.
5. Move shuttle cartridges from one location to another to see if the problem is effected.
6. If shuttle circuit does not have leakage or blockage, go to Step 4.

Step 4: Check Valves and Actuators

Theory

If one function is not operating properly, the problem is probably in a valve or actuators (cylinder or motor).

Test Valves

NOTICE: Perform these tests only after you have verified they will not damage components in the
circuit. Before troubleshooting, identify if there are any orifices in the circuit.

• Test electric valves with manual overrides if available.

• Consider switching hoses (re-routing) with another valve to determine if the problem is in the valve or
the actuator.
• For leakage on a valve that has PO checks, exchange checks with another location to determine if the
leakage is due to the PO check.
• For valves with work port relief, exchange reliefs with another location to determine if the relief is
malfunctioning.

Test Actuators

• For leakage in cylinders, perform a cylinder leak test.

• For motor actuators, measure the case flow.

How To Use a Digital Multimeter

How To Use a Digital Multimeter

A digital multimeter combines the functions a voltmeter, ohmmeter, and ammeter in one test instrument.
This is the preferred electrical troubleshooting tool.

To Measure Voltage
1. Set multimeter to a voltage range higher than the circuit voltage (e.g. 20V range for a 12V circuit).
2. Turn ignition switch to run position.
3. Place red lead on positive side of the component and black lead on negative side of the component.
4. Observe voltage reading.

To Measure Resistance (Ohms)

1. Set multimeter to the ohms setting.
2. Disconnect the battery or disconnect the component you are testing.

NOTICE: Never measure resistance in a circuit when voltage is present.

3. Place red lead on one side of the component and black lead on the other side of the component.
4. Observe resistance reading.

To Measure Current (Amps)

1. Set multimeter to the highest current setting.
2. Turn ignition switch to run position.
3. Disconnect a component or wire and place the meter “in series” with the circuit, so that current flows
from the disconnected wire, through the meter, and back to the point where the wire was disconnected.

NOTICE: Never use the multimeter to measure high current devices such as a starter motor, as
this current far exceeds the measurement capabilities of the meter. For these types of devices,
use a current clamp.

4. Observe current reading.

Basic Electrical Troubleshooting Technical Supplement
Basic Troubleshooting Checklist

Basic Troubleshooting Checklist

1. Identify the malfunction.
• Example: Work lights don’t work.

2. Identify the components in the circuit.

• Refer to schematic.

3. Perform a visual inspection of the circuit.

• Look for dirty, loose, or broken connections.
• Look for water in or around any electrical components.
• Inspect wiring for cracks, breaks, or other damage.
• Inspect seals for cracks, breaks, or other damage.
• Look for poor crimp terminals.

4. Test the suspect component(s).

• Check for proper supply voltage to the component.
• Check for resistance from the component to battery negative post or to chassis ground.
Resistance should not exceed 1.0 ohm.
• Check for correct output signal from the component

IMPORTANT: If any of the above are not present, go to step 5.

• Check for resistance across the component, if applicable.

5. Inspect the wiring harness for continuity.

NOTICE: Ensure that power is off before checking harness for continuity.
