FAN GP-BLOWER 2507563 - Caterpillar

Refer to Special Instruction, SEBU6250, "Caterpillar Machine Fluids Recommendations" for more information.Note: Multigrade oils must meet the requirements of Caterpillar TO-4M for use in transmissions. Multigrade oils that use high molecular weight polymers as viscosity index improvers may lose the viscosity effectiveness because of temporary shear and permanent shear of the polymer viscosity index improver. These types of multigrade oils are not recommended for Caterpillar transmissions. The Caterpillar TO-4M oil requirement includes a test for the shear stability of multigrade oil. If Caterpillar Transmission/Drive Train Oil (TDTO) is not available, use commercial oils that comply with Caterpillar TO-4 or TO-4M oil specifications.Note: Refer to Operation and Maintenance Manual, SEBU5898, "Cold Weather Recommendations for all Caterpillar Machines" for the selection of oil when the machine is operated below −20 °C (−4 °F).

(1) First Choice: Cat Arctic TDTO SAE 0W-20. Second Choice: Oils of full synthetic basestock that do not have viscosity index improvers and do meet the performance requirements of the Cat TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Third Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30.
(2) First Choice: Oils of full synthetic basestock that do not have viscosity index improvers and do meet the performance requirements of the Cat TO-4 specification for the SAE 30 viscosity grade. Typical lubricant viscosity grades are SAE 0W-20, SAE 0W-30, and SAE 5W-30. Second Choice: Oils that contain a TO-4 additive package and a lubricant viscosity grade of SAE 0W-20, SAE 0W-30, or SAE 5W-30
(3) Cat TDTO-TMS (Transmission Multi-Season) (synthetic blend that exceeds the Cat TO-4M multigrade specification requirements).
