Filtering Closed−Loop Traction Circuit

20252SL Rev A
Filtering of a closed−loop hydraulic system after a major component failure (e.g.
traction (piston) pump or wheel motor) is a requirement to prevent debris from
transmitting throughout the system. If a closed−loop hydraulic system filtering
tool is not used (to ensure system cleanliness) repeat failures and subsequent
damage to other hydraulic components in the system will occur. To effectively
remove contamination from closed−loop traction circuit, use of the Toro high
flow hydraulic filter and hydraulic hose kit are recommended (see
(page 2–13)).
1. Park machine on a level surface, stop engine and remove key from key
switch.
Before jacking up the machine, review and follow
Instructions (page 1–7).
2. Raise and support machine so all wheels are off the ground.
Note: If a wheel motor was replaced, install high flow filter to the inlet (when
traveling forward) of new wheel motor instead of to the inlet (when traveling
forward) of the traction pump. This will prevent system contamination from
entering and damaging the new motor.

1. Rear wheel motor
3. Thoroughly clean junction of hydraulic hose and lower fitting on rear wheel
motor (Figure 62). Disconnect hose from lower fitting on wheel motor.
4. Connect Toro high flow hydraulic filter in series between wheel motor
fitting and disconnected hose. Use hydraulic hose kit (see
(page 2–13)) to connect filter to machine. Make sure that fitting and hose
connections are properly tightened.
Use only hydraulic fluids specified in Operator's Manual. Other
fluids could cause system damage.
5. After installing high flow filter to machine, check and fill hydraulic reservoir
with new hydraulic fluid as required.
