RETAINER-PIN 7M4926 - Caterpillar

Lubrication System
The refill capacities for the engine crankcase reflect the approximate capacity of the crankcase or sump plus standard oil filters. Auxiliary oil filter systems will require additional oil. Refer to the OEM specifications for the capacity of the auxiliary oil filter. Refer to this Operation and Maintenance Manual, "Fluid Recommendations" for information about the types of fluids for use in the engine.

( 1 ) These values are the approximate capacities for the crankcase oil sump which include the standard oil filters that are installed at the factory. Engines with auxiliary oil filters will require additional oil. Refer to the specifications for the capacity of the auxiliary oil filter.For more information about lubricants, refer to Special Publication, SEBU6251, "Cat Commercial Diesel Engine Fluids Recommendations".Cooling System
To maintain the cooling system, the total cooling system capacity must be known. The approximate capacity for the engine cooling system is listed. External system capacities will vary among applications. Refer to the OEM specifications for the external system capacity. This capacity information will be needed in order to determine the amount of coolant/antifreeze that is required for the total cooling system.
