Usage:
914G (7ZM, 9WM) 918F (2CK, 3TJ, 5DL) 924F (4YN, 5NN, 6MN, 7PN) 928F (2XL, 7YM, 8AK) 928G (6XR, 7SR) Wheel Loaders IT14G (1WN, 8ZM) IT18F (5EJ, 6ZF) IT24F (4NN, 6KN) IT28F (1JL, 3CL) IT28G (8CR, 9AR) Integrated Toolcarriers
During the differential oil change add .47 L (.5 qt) of 1U-9891 Oil Additive when adding oil specified by the appropriate Operations and Maintenance manual to the differential. It is important to ensure the entire .47 L (.5 qt) of 1U-9891 Oil Additive is added before the differential oil has reached the maximum fill level. The 1U-9891 Oil Additive reduces both brake chatter and noise.
