| Question | Answer |
|---|---|
| Is this bearing universal across all sprayers? | No. It fits select models that specify part 165287 in their pump bill of materials. Always confirm in your model’s parts manual. |
| How many do I need? | Many pump assemblies use two bearings. Check the parts diagram for your specific pump to confirm quantity. |
| What symptoms indicate a worn bearing? | Excessive rod play, vibration, abnormal noise, or accelerated wear of packings/seals. |
| Can I replace the bearing without a full rebuild? | Yes, but it’s efficient to inspect/refresh adjacent wear parts (rod, packings, seals) when the pump is already disassembled. |
