Insert an appropriate dipstick into the hub. Use the dipstick to measure distance (A). Distance (A) should be between 82.55 mm (3.25 inch) and 85.72 mm (3.375 inch). Add oil, if necessary. Refer to Operation and Maintenance Manual, "Hub Oil (Flexxaire Fan) - Add" for the proper procedure to add oil.
Apply 6V-6640 Sealant to the threads of oil drain plug (1). Reinstall oil drain plug (1).
Check for leaks. A low oil level may indicate that a leak is present. Check the oil level of the hub more often, if the oil level is consistently low.
