PowrTwin part 325-005 is a Trip Spring used to provide return force or actuation tension within a mechanical trip mechanism. When the spring becomes weak, broken, or loses tension, the mechanism fails to reset or actuate properly. This replacement spring restores proper trip function and mechanical reliability on compatible PowrTwin, PowrTex, and PowrLiner units.

The PowrTwin 325-005 Trip Spring is a precision mechanical spring component designed to provide return force, actuation tension, or reset function within a trip mechanism on sprayers and striping machines. On compatible equipment including the extensive PowrTwin TM 8900 XLT, 12000GHD, 12000GH, 12000 XLT, 12000 XLT DI, 12000 Plus DI service, 12000 GHD, 8900GH, 6900GH, 6900 XLT, 6900 XLT DI, 6900 and 12000 Plus DI, 4900GH, 4900 XLT, 4900, 6900, 8900, 12000 Plus, 4500, 3500, and 3500 50th anniversary, as well as PowrTex 6900SF, 12000SV, and 0528919D, plus PowrLiner 8900, 8900 XLT, 8900 XLT SP, 6950_1, 6950, 6900 XLT, 6900 XLT SP, 6000, 5000, 4950, 4900, and 4900 XLT, this trip spring is essential for proper operation of pressure switches, relief valves, clutches, or mechanical actuators. A weak, broken, or fatigued spring fails to provide adequate force, causing the mechanism to stick, fail to reset, trip at incorrect pressures, or operate intermittently. Over time, repeated compression cycles, exposure to corrosive environments, or overheating can cause spring fatigue, reducing free length and tension. Replacing a worn trip spring restores proper mechanism function, consistent trip points, and reliable reset action. This genuine PowrTwin replacement spring meets original equipment specifications for wire diameter, coil count, free length, spring rate, and material composition. When installing a new trip spring, inspect the surrounding mechanism for wear or damage, ensure proper seating of spring ends, and verify correct operation through full travel. Users should always verify compatibility with their specific model and revision before installation.
| Return force | Provides force to reset mechanism after actuation |
|---|---|
| Trip point control | Determines pressure or force at which mechanism activates |
| Mechanical reliability | Ensures consistent operation of clutches, valves, or switches |
| Broken spring | Spring is visibly snapped or fractured |
|---|---|
| Loss of tension | Spring does not return mechanism to correct position |
| Fatigue or sagging | Spring has taken a set and no longer provides proper force |
| Corrosion damage | Rust or chemical attack weakening spring structure |

Trip mechanism problems are often caused by more than one component. When servicing the trip spring, these parts are commonly inspected at the same time.
Worn or sticking plungers can cause trip failure even with a new spring.
Leaking seals can affect hydraulic or pneumatic trip actuation forces.
Loose or damaged adjustment nuts affect spring preload and trip point.
