Housing Assembly Water Pump impeller
Application: EMD 645 / 710 water pump system
Part of our Water pump product line
The Housing Assembly Water Pump Impeller is identified by EMD Part No. 40004231. EMD parts references identify 40004231 as HOUSING-WATER PUMP, while specialized EMD 645/710 parts references identify it as an Impeller Housing. The part is used as a housing component within the EMD water-pump system and should be identified by its EMD part number and applicable engine or water-pump configuration when sourcing or replacing the component.
How This Part Works
The Housing Assembly Water Pump Impeller is a housing component of the EMD water-pump system. It provides the housing associated with the water-pump impeller and works with the other components of the pump assembly. The impeller housing is therefore an integral component of the water-pump arrangement and should be matched to the applicable pump configuration during maintenance or replacement.
Signs It's Time to Replace
- Visible housing damage: inspection may identify physical damage or deterioration of the water-pump impeller housing
- Wear on mating surfaces: relevant housing and mating surfaces should be inspected for abnormal wear or deterioration
- Corrosion or material deterioration: visible corrosion or deterioration of the housing should be assessed during inspection
- Impeller-area wear: the housing and impeller area should be checked for abnormal wear during water-pump maintenance
- Coolant leakage: leakage around the housing may indicate an issue with associated sealing components or mating surfaces
Apex focuses on EMD engine components and water-pump system parts for EMD applications. The Housing Assembly Water Pump Impeller is identified by the specific EMD Part No. 40004231, allowing customers to source the component using its established EMD reference rather than relying on a generic water-pump housing description. This part-number-based identification helps distinguish the 40004231 impeller housing from other EMD water-pump housing references, including EMD 40004233.
