This page previously carried the words fan motor in its title. That was wrong, and it has been corrected. Caterpillar lists 259-0815 as a 336D fan piston pump, and the matching 10R-8707 reference is the same pump rather than a motor. We would rather fix the record in public than leave a page that sends buyers to the wrong component.<\/p>\n

Where this pump sits in the circuit<\/h2>\n

On the 330D and 336D the cooling fan is turned by a fixed displacement piston motor, and the oil that drives it comes from this pump. Caterpillar’s specification for the closely related 345D describes the arrangement: the cooling fan is hydraulically driven with variable speed control based on ambient temperature, coolant temperature and hydraulic oil temperature. The pump is the component that varies; the motor is the component that converts. When a machine cannot reach full fan speed, either could be at fault, and the test that separates them is measuring delivery at the pump against drain flow at the motor.<\/p>\n

The third row matters because some listings describe 233-2530 as a pump. In Caterpillar’s service literature it is the rotating group of the fan motor assembly. If you are being offered a 233-2530 as a fan pump for a 336D, you are being offered the internals of a motor.<\/p>\n

Contexto de la m\u00e1quina<\/h2>\n

The 336D carries a Caterpillar C9 ACERT of 8.8 litre displacement producing 200 kW (268 hp) net flywheel power to ISO 9249 and SAE J1349, with main implement flow of 280 L\/min across two pumps, a 43 L\/min pilot circuit, equipment relief at 35,000 kPa and a cooling system holding 40 litre. The 330D shares the C9 platform at approximately 184 kW. Note that the 336D Series 2 is published at 265 L\/min per pump with a different power rating, and its fan drive parts should not be ordered from Series 1 data.<\/p>\n
