Komatsu drives the cooling fan hydraulically across its excavators, wheel loaders, dozers, graders and haulers, and the parts book separates the two halves of that circuit clearly: the pump assembly that meters the oil and the motor assembly that turns the fan. In Komatsu numbering within the 708 hydraulic group, the 1x series carries the pumps and the 7x series carries the motors, and Komatsu publishes the 708-7x items under the item name Motor Assembly.This section covers replacement hydraulic fan motors for Komatsu WA, PC, D, GD and HM series machines, including 418-03-33241 and 419-03-33242 for the smaller wheel loaders and the 708-7S and 708-7W units for the large excavators and haulers. Fan pumps, steering pumps and main hydraulic pumps are listed in the hydraulic pump categories instead, so a search for a fan part does not return the wrong circuit. Every unit is bench checked, photographed against your order and packed in a wooden case.
