Power Steering Pump Ford M2C134-D/C
Engine Crankcase Ford M2C121-E
(see note below)
Grease:
Front Wheel Bearings and all Grease Fittings-M1C75-A/B or M1C137-B

1) Viscosity grade selection for your climate:(see Figure 2)

American-Lincoln Technology 1-8
772 Operator’s Manual
OUTDOOR TEMPERATURES AND RANGES OF APPLICATION
In areas where prolonged periods of extreme temperatures are encountered, local lubricant practices are
acceptable, such as the use of SAE 5W, SAE 40 or SAE 50 grades of oil. These oils much be of API CD or
SF/CD Quality.
Engine crankcase oil drain intervals should be adjusted downward when diesel fuel sulfur content is above
0.5%. Consult your dealer for details of Engine Crankcase Oil Usage.
