Filtering the Closed-Loop Traction Circuit (continued)

6. Disconnect the balancing hose from the transmission fitting closest to the
transmission pump inlet for the pump to be filtered
cap on the fitting and steel plug in the balancing hose.
Using other hydraulic fluids could damage the hydraulic system.
Use the hydraulic fluids that are specified in the Operator's Manual.
7. After you install the high-flow filter to the machine, check and fill the reservoir
with the correct quantity of new hydraulic fluid.
8. Start the engine and run it at low-idle speed (1,400 rpm). Check for
hydraulic-fluid leaks at the filter and hose connections. Correct any leaks
before you proceed.
During this procedure, all the wheels will be off the ground and
rotating.
Ensure that the machine is well supported so it will not move and
accidentally fall to prevent injuring anyone around the machine.
While engaging the traction circuit, monitor the indicator on the
high flow hydraulic filter. If the indicator shows red, either reduce
the pressure on the traction pedal or reduce the engine speed to
decrease the hydraulic flow through the filter.
9. With the engine running at low-idle speed, slowly move the traction pedal to
the forward direction to allow flow through the traction circuit and high-flow
filter. Keep the traction circuit engaged in forward for 5 minutes while
gradually increasing both forward pressure on the traction pedal and engine
speed. Monitor the filter indicator to ensure that the green color is showing
during operation.
Note: When applying brakes to increase the traction system pressure,
ensure that the parking brake latch is not pressed. If the parking brake latch
is pressed, the engine will stop running.
10. With the engine running at high-idle speed (3,000 rpm) and traction pedal
moved to the forward direction, periodically apply brakes to increase pressure
in the traction circuit. While monitoring the filter indicator, continue this
process for 5 more minutes.
