Filtering the Closed-loop Traction Circuit

Sand Pro ® 3040 and 5040
20251SL Rev A
Filtering of a closed−loop hydraulic system after a major component failure
(e.g. traction (piston) pump or wheel motor) is required to prevent debris from
transmitting throughout the system. If a filtering tool is not used (to ensure that
the system is clean), repeat failures and subsequent damage to other hydraulic
components in the system will occur. To effectively remove contamination from
the closed−loop traction circuit, use of a Toro bidirectional high flow hydraulic
filter and hydraulic hose kit is recommended; refer to
Kit (page 2–17).
1. Park machine on a level surface, lower any attachments, set the key switch
to the O position and remove the key from the switch.

Review and follow the
the machine.
3. Raise all of the wheels off the ground and support the machine with jack
stands.
4. Install the hydraulic filter directly upstream of the new component to prevent
system contamination from entering and damaging the new component.
A. If the traction (piston) pump or front wheel motor was replaced, remove
the center shroud.
B. Thoroughly clean the connection between the hydraulic hose and tube
