2. Unthread and discard the hydraulic fluid filter
element.
An older style hydraulic filter contained a filter
cartridge. Remove the outer case and discard
the cartridge.
NOTE: Be aware the hydraulic filter is below the top

will drain from the reservoir. Discard all hydraulic fluid
drained from the system. Drained hydraulic fluid may
contain foreign material harmful to the hydraulic
system.
3. Apply a thin coat of hydraulic fluid to the seal of
the new hydraulic fluid filter element.

HYDRAULIC PUMPS
The machine propelling pump is a variable
displacement hydraulic piston pump. It is driven by
the electric motor via a v-belt.
The machine accessories pump is a hydraulic gear
pump. It is tandem mounted to the hydraulic piston
pump.
After repairing or replacing a hydraulic pump, or
when system contamination is likely, change the
hydraulic fluid in the reservoir and the hydraulic fluid
filter. Then the proper start and break-in procedure
must be followed to prevent possible damage to the
pump.
