Seal - Water Pump Outer
Seal - Water Pump Outer
Application: EMD 710-series water pump assemblies
Part of our Water pump product line
The Seal - Water Pump Outer is identified by EMD Part No. 9526863 and DLW Part No. 16241459. EMD parts references identify 9526863 as the outer seal for the water pump, while the EMD 710 water-pump parts listing cross-references EMD 9526863 with DLW 16241459. The seal is a component of the water-pump assembly and should be identified using the correct EMD and DLW part numbers when sourcing or replacing the component.
How This Part Works
The Seal - Water Pump Outer is a sealing component within the EMD water-pump assembly. Its function is to provide sealing at the designated water-pump sealing interface and help prevent coolant leakage from the pump assembly. The outer water-pump seal works as part of the complete seal arrangement, which also includes the inner water-pump seal, seal retainer, and associated components.
Signs It's Time to Replace
- Water or coolant leakage: leakage from the water-pump seal area can indicate deterioration or damage to the outer seal
- Seal deterioration: visible deterioration or damage to the sealing material should be assessed during inspection
- Loss of sealing effectiveness: a compromised seal can result in leakage from the water-pump assembly
- Improper seal condition: deformation, damage, or abnormal wear should be investigated before continued service
- Repeated water-pump leakage: recurring leakage should prompt inspection of the outer seal and associated sealing components
Apex focuses on EMD engine components and water-pump system parts for EMD applications. The Seal - Water Pump Outer is identified by the specific EMD Part No. 9526863 and DLW Part No. 16241459, allowing customers to source the component using established EMD and DLW references. This part-number-based identification helps distinguish the outer water-pump seal from the associated inner seal, retainer, and other components within the EMD water-pump assembly.
