1-13650068-9 Water Pump supports EX300-5 6SD1 coolant circulation for B2B excavator parts repair, replacement inventory, and wholesale sourcing.
The 1-13650068-9 Water Pump YNF13544 is supplied for compatible EX300-5 excavators using the 6SD1 engine reference. It is installed within the engine cooling system, where coolant circulation is maintained between the engine and corresponding heat-dissipation components.
A properly operating water pump is important because heat generated during engine operation must be transferred through the coolant circuit. Leakage around the pump, abnormal bearing condition, damaged internal components, or reduced coolant circulation can indicate that replacement is required.
For B2B buyers, the 1-13650068-9 6SD1 water pump should be verified by part number, EX300-5 machine reference, engine model, mounting pattern, connection positions, pulley or drive interface where applicable, and existing-part photos. Gasket and accessory inclusion should also be confirmed from the supplied product configuration before bulk purchasing. Accurate verification helps reduce incorrect inventory, installation delays, and repeat freight.
