Changing the Hydraulic FiltersRemoving the Traction-pedal AssemblyRemove the traction-pedal assembly as follows:1. Remove the 4 hex-flanged head bolts that secure thattraction-pedal assembly to the chassis of the machine(Figure 115).Figure 1151. Hex-flanged head bolts 3. 6-pin connector(traction-pedal sensor)2. Traction-pedal assembly 4. 6-socket connector(machine harness)2. Disconnect the 6-socket connector of the machineharness from the 6-pin connector of the traction-pedalsensor (Figure 115).3. Remove the traction-pedal assembly from the machine(Figure 115).Changing the Hydraulic-charge FilterService Interval: Every 500 hoursNote: Change the hydraulic-return filter when you changethe hydraulic-charge filter.Note: You can access the hydraulic-charge filter from underthe right side of the machine, behind the hydraulic reservoir(Figure 116).1. Remove the traction-pedal assembly; refer to Removingthe Traction-pedal Assembly (page 72).2. Place a container under the hydraulic-charge filter(Figure 116).Figure 1161. Container suitable forhydraulic fluid3. Hydraulic-charge filter2. Sharp object3. Rotate the hydraulic-charge filter counterclockwise andremove the filter (Figure 116).Note: Discard the filter.4. Apply a thin layer of the specified hydraulic fluid tothe O-ring of the new filter.Important: Do not use a filter strap wrench totighten the filter. A strap wrench can dent thefilter, causing it to leak.5. Fill the new charge filter with the specified hydraulicfluid, 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 additionalhalf turn after the filter makes contact with the filterhead.7. Repeat steps 3 through 6 for the other charge filter8. Check the level of the hydraulic fluid in the hydraulicreservoir; refer to Checking the Hydraulic-Fluid Level(page 27).9. Start the engine and let it idle for 1 or 2 minutes.10. Shut off the engine, and check for leaks around thefilter area.11. Check the level of the hydraulic fluid in the hydraulicreservoir, and add fluid, if necessary; refer to Filling theHydraulic-fluid Reservoir (page 71).72
