As a genuine OEM component sourced directly through the Multiquip parts network, the part is manufactured to the exact specification required for correct operation in these generator applications. Fitment spans the full DCA Tier 4 Super-Silent and diesel-powered generator lineup, making this a high-confidence replacement for service technicians and fleet maintenance teams. DHS Equipment stocks this part to support fast, accurate repairs on DCA series generators across a wide range of operating configurations.

Key Features

• Genuine OEM Spring Tension Integrity — Manufactured to the exact load and deflection specification required for correct mechanical function in DCA series generator assemblies.
• Direct Drop-In Replacement — Engineered to seat and engage identically to the original component, with no rework needed to existing mounting points or adjacent hardware.
• Broad DCA Series Fitment — Confirmed for DCA70SSIU4F, DCA150SSJU4F3, DCA180SSJU4F3, DCA400SSI4F/4F3/4F3PB, DCA600SSV4F3, DCA600SSV4F3B, and DCA600SSV4F3PB generator models.
• Consistent Spring Return Performance — A correctly tensioned end spring maintains the mechanical return action that keeps generator components cycling smoothly under load.
• Verified Multiquip Part Number — Order with confidence: this part is the exact Multiquip OEM part number for this spring across all listed DCA generator configurations.

An end spring provides the return tension or positional retention force needed to keep a mechanical assembly seated, closed, or correctly positioned during operation. In generator applications, springs of this type are often found in governor linkages, fuel control mechanisms, or other actuated assemblies where consistent return force is critical to stable engine speed and output regulation. A fatigued or broken end spring can cause erratic governor response, unstable voltage output, or failure of a linked component to return to its home position — all of which can disrupt generator performance or cause downstream electrical issues.
