Is one final drive positioned so that the oil fill/drain plug is at the top?

Did you use an 8 mm (5/16 inch) allen wrench to remove the oil check plug?

Check the oil level. The oil should be near the bottom of the opening for the oil check plug.

Did you add oil through the opening for the oil fill/drain plug, if necessary?

Note: Overfilling the final drive will cause the seals on the travel motor to allow hydraulic oil or water to enter the final drive. This may contaminate the final drive.

Did you install the oil plugs and tighten them to a torque of 27 ± 1 N·m (20 ± 0.7 lb ft)?
