The differential and final drives are not equipped with sampling valves. Obtaining an oil sample will require the use of a vacuum pump or equivalent. Extract the oil through the filler plug openings. Sample the oil from both differentials and from each final drive.
Note: When you obtain a sample from the final drives, position the wheels so that the final drive filler plugs are even with the centerline of the wheel.
Reference: Refer to Operation and Maintenance Manual, "S·O·S Oil Analysis" and to Special Publication, PEHP6001, "How To Take A Good Oil Sample" for information about obtaining a sample of the differential and final drive oil.
