Problem Possible Cause Corrective Action
The fitting(s), hose(s), or tube(s) are
loose or damaged. Secure or replace loose or damaged
hydraulic connections. Hydraulic fluid is leaking from the
system.
The O-ring(s) or seal(s) are missing or
damaged. Install a new O-ring(s) or seal(s).
The hydraulic fluid level in the hydraulic
tank is low. Adjust the hydraulic fluid level.
The hydraulic system has a wrong type
of fluid. Replace the hydraulic fluid.
Note: Refer to the traction unit
Operator’s Manual for hydraulic fluid
specifications.
The incompatible hydraulic fluids are
mixed in the system.
Replace the hydraulic fluid.
There is water in the hydraulic system. Replace the hydraulic fluid.
The hydraulic fluid foams excessively
causing fluid leakage from the hydraulic
tank breather.
The pump suction line has an air leak. Replace the pump suction line.
The hydraulic fluid level in the hydraulic
tank is low. Adjust the hydraulic fluid level.
The suction filter or suction line is
damaged, loose, or clogged. Secure, clean or replace the suction
filter or suction line.
The hydraulic fluid is contaminated or
the fluid viscosity is too light. Replace the hydraulic fluid.
Note: Refer to the traction unit
Operator’s Manual for hydraulic fluid
specifications.
The engine RPM is too low.
Verify engine RPM and adjust if
necessary.
The traction pump tow (bypass) valve
is open or damaged. Close or replace the traction pump
bypass valve.
The charge pressure is low. Verify charge pressure; refer to
Hydraulic Pump Charge Pressure Test
in Chapter 5 – Hydraulic System.
The hydraulic pump is worn or
damaged.
Verify hydraulic pump operation; refer
to Hydraulic Pump Flow and Relief
Pressure Test in Chapter 5 – Hydraulic
System.
The hydraulic drive motor is worn or
damaged. Repair or replace the hydraulic drive
motor.
The hydraulic system operates hot
(exceeds 95° C (203° F).
Note: If a traction circuit component
has internal wear or damage, it
is possible that the other traction
components are also damaged.
