Changing the Hydraulic Filters
Removing the Traction-pedal Assembly
Remove the traction-pedal assembly as follows:
1. Remove the 4 hex-flanged head bolts that secure that
traction-pedal assembly to the chassis of the machine
(Figure
109).

2. Disconnect the 6-socket connector of the machine
harness from the 6-pin connector of the traction-pedal
sensor
(Figure
109).
3. Remove the traction-pedal assembly from the machine
(Figure
109).
Changing the Hydraulic-charge Filter
Service Interval: Every 500 hours
Note: Change the hydraulic-return filter when you change
the hydraulic-charge filter.
Note: You can access the hydraulic-charge filter from under
the right side of the machine, behind the hydraulic reservoir
(Figure
110).
1. Remove the traction-pedal assembly; refer to
the Traction-pedal Assembly (page
2. Place a container under the hydraulic-charge filter

3. Rotate the hydraulic-charge filter counterclockwise and
remove the filter
Note: Discard the filter.
4. Apply a thin layer of the specified hydraulic fluid to
the O-ring of the new filter.
Important: Do not use a filter strap wrench to
tighten the filter. A strap wrench can dent the
filter, causing it to leak.
5. Fill the new charge filter with the specified hydraulic
fluid, allow the filter element to saturate with the fluid,
and then pour out the excess fluid.
6. Install the new filter.
Note: Use your hands to tighten the filter an additional
half turn after the filter makes contact with the filter
head.

8. Check the level of the hydraulic fluid in the hydraulic
reservoir; refer to
(page

9. Start the engine and let it idle for 1 or 2 minutes.
10. Shut off the engine, and check for leaks around the
filter area.
11. Check the level of the hydraulic fluid in the hydraulic
reservoir, and add fluid, if necessary; refer to
