Traction Circuit (Closed-Loop) Component Failure
The traction system of the Outcross 9060 machine consists of two closed-loop
circuits, each with it’s own piston (traction) pump, drive axle motor, and control
valves. The two traction pumps (P1) and (P2) are part of the tandem piston
(traction) pump. Pump (P1) supplies the front traction circuit, and pump (P2)
supplies the rear traction circuit. If a component in one of the traction circuits
should fail, unwanted material and contamination from the damaged component
will circulate throughout that traction circuit. This contamination can damage
other components in that circuit. The contamination must be removed as soon
as possible to prevent additional component failure.
The recommended method of removing contamination from a traction circuit is to
temporarily install a Toro high flow hydraulic filter into the traction circuit; refer to
High Flow Hydraulic Filter Kit (page 2–17)
. If a traction circuit failure is suspect,
the filter should be installed before connecting hydraulic test gauges to test
traction circuit components or after replacing a failed traction circuit component.
The filter will ensure that contaminates are removed from the closed-loop traction
circuit and thus, prevent additional component damage. Refer to
Closed-Loop Traction Circuit (page 5–54)
for additional information on using the
Toro high flow hydraulic filter.
Note:
If traction circuit contamination exists, the traction pump and drive axle
motor drains could allow contaminates to enter the hydraulic tank.
The alternative to using the Toro high flow hydraulic filter kit after a traction circuit
component failure would be to disassemble, drain and thoroughly clean all the
components, the hydraulic tank, and the hydraulic tubes and hoses in the traction
circuit. If any debris remains in the traction circuit and the machine is operated,
the debris can cause additional circuit component failures.
