the track on one side. Move the throttle control dial 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.

3. Wait 10 minutes for the gear oil to cool.
4. Place a suitable container under the final drive.

plugs to relieve any internal pressure.
NOTE:
See “Other Approved Lubricants” on page
13 for the final drive capacity.

NOTE:
Refer to “Recommended Lubricants, Fuels, and Engine Coolant” on page 5-10 for the recommended
final drive oil.

opening.
