Part 155-001 is a replacement spring for compatible Admiral and Commander spray equipment. This spring provides force or tension in various mechanisms such as valves, controls, or return systems. When the original spring becomes weakened, sagged, or broken, replacement restores proper mechanical function.

The 155-001 spring is a direct replacement component for Admiral and Commander spray equipment. Springs are fundamental mechanical components used throughout spray equipment to provide force, tension, or return action. They are found in various applications including valves (to hold them closed or return them to a neutral position), control mechanisms (to provide detents or return levers), pump assemblies (to maintain contact between components), and tensioners (to keep belts or cables tight). A properly functioning spring provides a specific, calibrated force. A weakened, sagged, or broken spring can cause a mechanism to fail to return, operate with insufficient force, or malfunction entirely. This replacement spring is manufactured to exact specifications for wire diameter, coil count, free length, and spring rate to match the original. It is made from high-grade spring steel to ensure consistent performance and long service life. Installation requires careful handling to avoid damaging the spring and proper positioning within the assembly. Regular inspection during maintenance helps identify springs that have lost tension or show signs of fatigue.
| Force application | Provides mechanical force or tension |
|---|---|
| Return action | Returns components to starting position |
| Shock absorption | Cushions impacts in mechanisms |
| Weakened / sagged | Spring no longer provides sufficient force |
|---|---|
| Broken spring | Spring has fractured |
| Corrosion damage | Rust has compromised spring integrity |
| Mechanical binding | Spring deformation causes uneven operation |

When replacing the spring, inspect these associated components to ensure proper mechanism function.
Check parts that interact with spring for wear.
Ensure spring seats are clean and undamaged.
Inspect bolts, pins, or clips for damage.
