High Flow Hydraulic Filter Kit
Toro Part Number: TOR6011
The high flow hydraulic filter kit is designed with
large flow (150 L/minute or 40 gallons/minute)
and high pressure (34,500 kPa or 5,000 psi)
capabilities. This kit provides for bi-directional
filtration which prevents filtered unwanted material
from entering into the circuit regardless of the flow
direction.
If a component failure occurs in the closed loop
traction circuit, contamination from the damaged
part will remain in the circuit until you remove it.
Install a high flow hydraulic-fluid filter into the circuit
when you connect the hydraulic test gauges in
order to test the traction circuit components or after
you replace a failed traction circuit component
(e.g., piston pump or wheel motor). This filter
removes contamination from the hydraulic fluid in
the traction circuit, thereby preventing additional
component damage.
Note: This kit does not include the hydraulic hoses;
refer to Hydraulic Hose Kit (page 2–12) .
Note: The replacement filter element is Toro
Part No. TOR6012. The filter element canister
tightening torque is
34 N∙m (25 ft-lb) .
Remote Starter Switch
After flushing the hydraulic system or
replacing a hydraulic component (e.g.
gear pump, piston pump, drive motor), it is
necessary to prime the hydraulic pumps.
A remote starter switch can be used for
this purpose. A remote starter switch
can be purchased locally or fabricated as
follows.
IMPORTANT: When using a
remote starter switch, it is highly
recommended to include a 20 amp
in−line fuse between the battery and
switch connector for circuit protection.
A remote stater switch can also be
constructed using Toro switch #106−2027,
a length of 14 gauge wire, a 20 amp
in−line fuse, two (2) alligator clips and
necessary connectors. Connecting the
wire to switch terminals 1 and 2 will allow
the momentary switch contacts to be used
for the remote starter switch.
Note: For information on using the remote
starter switch to prime the hydraulic
pumps.
