Chapter Overview
This chapter provides information on inspection, disas-
sembly and assembly of major hydraulic components.
Personal Safety
Improper or incomplete maintenance/repair of a Rubber
Track Utility Vehicle can be dangerous and may result in
machine damage, injury or even death.
Do not attempt to perform repair or maintenance on a
Rubber Track Utility Vehicle until you have read and fully
understood the information in this manual.
Refer to the Operation and Maintenance manual for
instructions regarding proper machine operation tech-
niques before operating any Rubber Track Utility Vehicle.
Prior to performing service work on a Rubber Track
Utility Vehicle, read and understand Chapter 1
(Product Safety) for personal safety information.
When servicing any hydraulic component, make sure
the machine is off and cool and that all of the hydraulic
actuators are relaxed prior to disconnecting or remov-
ing any component from the system.
When servicing any hydraulic component, keep in
mind that any scratches or damage that can be felt
with a fingernail on surfaces that parts move, slide, roll
or rotate upon indicate a need for part replacement.
Hydraulic components must be kept extremely clean to
ensure proper function and service life. Do not assem-
ble any components that have not been inspected for
damage and thoroughly cleaned prior to assembly.
The hydraulic system fluid should be changed fol-
lowing any hydraulic component service according
to the procedure described on page 4-8.
Disassembly & Assembly
Disassembly and assembly procedures are provided
for the following components:
• Hydraulic Cylinders
• Auxiliary Control Valve
• Drive motor
• Drive Pump
• Auxiliary Pump
Note: Procedures are provided for only those components
listed above. However, exploded parts diagrams exist in the
SC-50 parts manuals to serve as visual aids in the assembly
and disassembly of other system components.
Hydraulic Cylinder
Disassembly
1. With machine off and cool and with hydraulic actu-
ators relaxed, disconnect and cap hoses from the
cylinder(s) to be serviced.
Note: When servicing cylinders, the attached components
must be supported in a manner that allows the cylinders to
be safely removed and installed. (dump box, blade, etc.)
2. Remove the cylinder(s) and secure it in a bench
vise to aid in disassembly. (figure 13-1)
3. Place a suitable catch container beneath the rod
end of the cylinder to catch any hydraulic oil that
may leak out upon disassembly.

NOTICE
!WARNING!
Disassembly of hydraulic components should only be performed
