Product Overview
The pump circulates coolant through the engine and radiator to control operating temperature under load. Coolant leaking from the pump area, bearing noise, shaft play, or repeated overheating can point to a failing water pump after belts, radiator flow, thermostat operation and coolant level are checked.
Parts listings for this pump connect the 314-9905 / 335-9118 family with Caterpillar 3044C industrial engines and compact wheel-loader applications such as the 906, 906H and 907H. Some catalogs also show additional related water-pump numbers, so comparing the casting and bolt pattern is recommended.

Frequently Asked Questions
What are common signs of a failing water pump?
Coolant leakage, bearing noise or play, overheating and poor coolant circulation are common symptoms, though the entire cooling system should be diagnosed.
Does this fit every C3.4 application?
No. Verify the machine and engine serial number as well as the pump configuration before ordering.
Is the pulley always included?
Do not assume accessory hardware is included unless shown in the product photos/listing contents.
