Part number 759-514 is a spring washer used in LC800 pump assemblies and PowerLiner series airless sprayers. This washer provides tension and prevents loosening of critical components due to vibration. A worn or compressed spring washer can lead to loose connections, leaks, or component failure. Replacing it restores proper clamping force and reliable operation.

The 759-514 spring washer is a specialized fastener component designed for use with LC800 pump assemblies and compatible PowerLiner sprayers. Unlike standard flat washers, spring washers (also known as split lock washers or Belleville washers) provide axial tension that resists loosening under vibration, thermal cycling, and dynamic loads.
In airless sprayers, spring washers are typically used in critical bolted connections such as pump mounts, motor attachments, and manifold assemblies. Over time, these washers can lose their spring tension due to metal fatigue, corrosion, or over-torquing. A compressed or broken spring washer allows the fastener to loosen, leading to leaks, misalignment, and potential component damage. Replacing with genuine 759-514 restores proper clamping force and ensures long-term reliability.
| Locking action | Prevents nuts and bolts from loosening due to vibration |
|---|---|
| Tension maintenance | Maintains consistent clamping force under dynamic loads |
| Compensation | Compensates for minor thermal expansion and wear |
| Sealing assistance | Helps maintain gasket compression in sealed joints |
| Flattened | Washer no longer has spring tension (compressed flat) |
|---|---|
| Cracked/broken | Visible cracks or fracture in the washer |
| Corroded | Rust or pitting that weakens the material |
| Loose fasteners | Recurring loosening of bolted connections |
| Fluid leaks | Leaks at gasketed joints where washer provides tension |

When replacing spring washers, consider inspecting these associated components:
Check threads for damage; replace if worn or corroded.
If the joint was leaking, the gasket may also need replacement.
Some applications use both flat and spring washers; inspect both.
