CABLE AS 3077629 - Caterpillar

Problem: The filler plug has metal shavings.
Probable Cause
Mechanical failure of one or both of the final drives
Mechanical failure of any of the components that are located inside the rear axle housingProblem: The oil level in a final drive is too high and the oil level in the hydraulic tank is too low.
Probable Cause

(3) Seal assembly
(4) Duo-Cone seal
(5) Duo-Cone seal
(6) O-ring seal
The brake cooling oil is leaking into the final drive. Duo-Cone seal (5) at the rear wheel brake has failed.
The brake cooling oil is leaking into the final drive. Seal assembly (3) at the rear wheel brake has failed.
The brake cooling oil is leaking into the final drive. O-ring seal (6) at the rear wheel brake has failed.Note: To determine the wheel that is leaking, perform the test in the Air System and Brakes Systems Operation/Testing and Adjusting, "Internal Brake Leakage - Check".Problem: The oil level in a final drive is too low.
Probable CauseThe probable cause is the failure of the O-ring seal on the final drive housing.Check: Check the oil level in the rear axle housing

Location of the sight glass for the rear axle housing
Use the sight glass to check the oil level in the rear axle housing. The oil level should be at the bottom of the sight gauge. Check for leakage under the housing. Add oil, if necessary. Refer to your Operation and Maintenance Manual in order to determine the correct oil to use.Problem: The oil level in the rear axle housing is too high and the oil level in the hydraulic tank is too low.

Probable CauseThe oil of the differential and bevel gear is leaking into the transmission case. This could be caused by one of the following problems:
Failure of the pinion seal in the differential
The center plug of the differential pinion is not installed or the center plug is leaking.Check: Check the rear axle power train filter

(8) Rear axle power train filter Remove rear axle power train filter (8). Inspect the filter for foreign material. The filter might need to be cut apart for inspection.Note: Rear axle power train filter (8) has a bypass valve. A bypass valve allows oil to bypass the oil filter when the pressure difference between the inlet oil and the outlet oil at the oil filter is too high.The pressure
