🔌 Function

The compression spring is compressed in service and pushes back with a predictable force, returning the component it serves to its rest position and maintaining preload. That consistent force is what keeps injection timing and travel repeatable.

⚠️ Common Signs of Failure

• Reduced free length or measurably weakened spring force
• Fracture or cracking of a coil
• Component not returning fully to its rest position
• Corrosion or pitting reducing wire section
• Erratic fuel delivery or timing traced to lost preload

🛠️ Service Notes

• Compare the new spring with the one removed for free length and coil condition; a spring that has taken a set or lost length is past its useful life
• Look over the old spring for corrosion pitting, bright rub marks and cracked or broken coil ends, and check whatever it bears against for the same wear
• Never stretch, shorten, grind or heat a spring to alter how it behaves — fit the correct part instead
• Seat the spring squarely in its recess or over its guide with the ends fully home, so it cannot cock over or bind in service
• Where springs work as a group, renew them together so the load stays even across the set
