Filtering the Closed-Loop Traction Circuit (GreensPro 1260)
Filtering a closed-loop hydraulic system after a major component failure
(e.g., hydraulic pump or hydraulic motor) is required to prevent debris from
transmitting throughout the system. If a filtering tool is not used to ensure the
system cleanliness, repeat failures and subsequent damage to other hydraulic
components in the system, will occur. To effectively remove the contamination
from the closed-loop traction circuit, use of a Toro bidirectional high flow hydraulic
filter and hydraulic hose kit is recommended; refer to
High Flow Hydraulic Filter
Kit (page 2–13) .
1. Park the machine on a clean, level surface with the engine off. Lower and
lock the transport wheels (drive roller off the ground).
2. Read and adhere to the information provided in General Precautions for
Removing and Installing the Hydraulic System Components (page 5–35) .
3. Install a temporary hydraulic filter directly upstream of the new component as
follows:
A. If the hydraulic pump was serviced or replaced, remove the transmission
cover and disconnect the hose at the pump “A” port ( Figure 30 ).
B. If the hydraulic motor was serviced or replaced, disconnect the hose
at the motor “A” port ( Figure 30 ).

4. Connect the Toro high flow hydraulic filter in series between the disconnected
fitting and hose. Use the hydraulic hose kit to connect the filter to the
machine; refer to
Hydraulic Hose Kit (page 2–13) . Ensure that the fitting and
hose connections are properly tightened.
