Change the Final Drive Oil
NOTE:
If the final drive oil is cold, it should be warmed prior to changing. Use the bucket as a support to lift
the track on one side. Push the throttle control lever to MIN (low idle) and operate the raised track for
5 minutes. Lower the track.
1. Park the machine to position the drain plug (3) at the
bottom of one of the final drives.
2. Prepare the machine for service. See “Maintenance
3. Wait 10 minutes for the gear oil to cool.
4. Collect a final drive oil sample. See “Collect Final Drive
5. Place a suitable container under the final drive.
6. Slowly loosen and remove the oil level (2) and fill (1)
plugs to relieve any internal pressure.
NOTE:
For final drive oil capacity, see “Fluid Capacities” on page 5-10.
7. Remove the drain plug and allow the oil to drain.
8. Install the drain plug and tighten to 36 lb-ft (49 N•m).
9. Add new gear oil through the fill plug opening. Fill until the gear oil is at the lower edge of the level plug
opening.
10. Install the oil level and fill plugs. Tighten the plugs to 12.5 lb-ft (17 N•m).
11. Repeat this procedure on the other final drive.
CAUTION!
•
Allow the final drive to cool before servicing. Hot oil may cause burns or other serious
injury.
•
The final drive gear case may be under pressure. Remove the plugs slowly to prevent
injury.
Failure to follow these precautions could result in injury.
NOTICE!
Dispose of used oil and strainer in accordance with all applicable environmental regulations.
Failure to do so could result in damage to the environment.
