Bearing — Ball, Water Pump Drive-Gear End
Bearing — Ball, Water Pump Drive-Gear End
Application: EMD water pump assemblies — drive-gear end
Part of our Water pump product line
The Bearing — Ball, Water Pump Drive-Gear End is identified by EMD Part No. 908410 and DLW Part No. 16150417. EMD water-pump parts references specifically identify 908410 as the Ball Bearing for the Water Pump Drive Gear End, while Indian Railways vendor documentation cross-references EMD 908410 with DLW 16150417. The bearing is part of the EMD water-pump assembly and is included in Water Pump Repair Kit 40000927.
How This Part Works
The Bearing — Ball, Water Pump Drive-Gear End supports the drive-gear end of the water-pump rotating assembly. It allows the associated rotating components to operate with controlled friction and supports proper shaft rotation within the water-pump assembly. Correct bearing condition is important for maintaining reliable water-pump operation.
Signs It's Time to Replace
- Abnormal bearing noise: unusual noise during water-pump operation can indicate bearing deterioration
- Excessive play: abnormal radial or axial movement can indicate wear or deterioration of the bearing or associated components
- Rough rotation: resistance, roughness, or irregular rotation should be investigated
- Vibration: abnormal water-pump vibration can be associated with deterioration of rotating or supporting components
- Visible damage or corrosion: physical damage, corrosion, or deterioration identified during inspection should be assessed for serviceability
- Water-pump operating concerns: abnormal pump operation should prompt inspection of the drive-gear-end bearing and associated rotating components
Apex focuses on EMD engine components and water-pump system parts for EMD applications. The Bearing — Ball, Water Pump Drive-Gear End is identified by the specific EMD Part No. 908410 and DLW Part No. 16150417, allowing customers to source the component using established EMD and DLW references. Its precise identification as the drive-gear-end water-pump bearing helps distinguish it from the separate impeller-end bearing, EMD 908415 / DLW 16150405.
