Support Housing – Water Pump
Support Housing – Water Pump
Application: EMD water pump assemblies
Part of our Water pump product line
The Support Housing – Water Pump is identified by EMD Part No. 8329900 and DLW Part No. 16120929. EMD parts references identify 8329900 as the Support Housing Assembly, while specialized EMD locomotive-parts references identify it as the Support Housing for the Water Pump. EMD water-pump documentation also lists 8329900 as the support housing used with the water-pump assembly. For procurement and maintenance, the component should be identified using the correct EMD and DLW part numbers and applicable water-pump configuration.
How This Part Works
The Support Housing – Water Pump is the support housing component of the EMD water-pump assembly. It provides the housing and supporting structure for associated water-pump components within the assembly. EMD maintenance documentation also records a revision to the 8329900 water-pump support housing that added a 1/8 × 1-3/8 inch roll pin across the lube-oil drain hole to prevent steel bearing balls from entering the accessory gear train in the event of a bearing failure.
Signs It's Time to Replace
- Visible housing damage: cracks, deformation, or other physical damage to the support housing should be assessed during inspection
- Wear at mating surfaces: abnormal wear or deterioration at the housing's associated mating surfaces should be investigated
- Corrosion or material deterioration: visible corrosion or deterioration of the housing should be evaluated for serviceability
- Bearing or support concerns: abnormal condition of associated water-pump bearings or supporting components should prompt inspection of the support housing
- Oil or coolant leakage: leakage around the support housing and its associated interfaces should be investigated to identify the source
- Drain-hole or roll-pin condition: on the revised housing arrangement, the roll pin and its installation should be checked during applicable maintenance
Apex focuses on EMD engine components and water-pump system parts for EMD applications. The Support Housing – Water Pump is identified by the specific EMD Part No. 8329900 and DLW Part No. 16120929, allowing customers to source the component using established EMD and DLW references. Its identification as the water-pump support housing helps distinguish it from the separate impeller housings and other housing components used within the EMD water-pump system.
