Hydraulic System: Service and Repairs
1. Before removing any parts from the hydraulic system, relieve any residual
pressure from the hydraulic system; refer to
Hydraulic System (page
2. Clean the machine before you disconnect, remove, or disassemble the
hydraulic components.
Note: Cleanliness is necessary whenever you work on the hydraulic
equipment. Ensure that you clean the hydraulic components, hoses,
connections, and fittings.
3. Label all the disconnected hydraulic lines and hoses for proper installation
after repairs are completed.
4. Record the position of the hydraulic fittings (especially elbow fittings) on the
hydraulic components before removal.
Note: Mark the parts, if necessary before removal and ensure that they are
aligned properly when installing the hydraulic fittings, hoses, and tubes.
Before disconnecting or doing any work on the hydraulic system,
release all the pressure in the system; refer to
from the Hydraulic System (page
5. The hydraulic fluid may be hot. Be careful when you loosen and remove
the hydraulic system components.
6. Install clean caps or plugs on the hydraulic lines, hydraulic fittings, and
components that are left open or exposed to prevent hydraulic system
contamination. Cap or plug the opening as soon as the opening is exposed.
1. Check the hydraulic-fluid level in the hydraulic reservoir and add correct
quantity of fluid if necessary. Use the hydraulic fluids that are specified in
the traction unitOperator's Manual.
Drain and fill the hydraulic reservoir and change the oil filter if the
component failure is severe or the system is contaminated; refer to
the traction unit Operator's Manual.
2. Lubricate the O-rings and seals with clean hydraulic fluid before installing
the hydraulic components.
3. Remove all the caps or plugs from the hydraulic tubes, hydraulic fittings, and
components before connecting them.
4. Use proper tightening procedures when installing the hydraulic hoses and
fittings; refer to Installing Hydraulic Hoses and Tubes (O-Ring Face Seal
