The Multiquip EM20707 Governor Spring is a genuine OEM component designed for STX55Y6 and STX55J6 series hydrostatic ride-on power trowels. As a direct Multiquip OEM part, it is manufactured to the exact specifications required by these machines, ensuring proper governor operation and consistent engine response. Confirm your model code before ordering to ensure this is the correct spring for your unit.

Key Features

  • Genuine OEM Spring Tension: — Manufactured to the precise tension rating required for correct governor actuation on STX55 series trowels — not an approximation.
  • Direct OEM Replacement: — Installs in place of the original spring with no modification to the governor linkage assembly.
  • Confirmed STX55 Fitment: — Verified for STX55Y6 and STX55J6 hydrostatic ride-on power trowels.
  • Engine Speed Stability: — A correctly tensioned governor spring maintains steady RPM under varying blade load, which is critical for consistent finishing quality across a slab.
  • Fuel System Safety Relevance: — A worn or broken governor spring can cause uncontrolled engine over-speed or under-speed conditions; replacing it promptly restores safe, controlled engine operation.

The governor spring is a key component in the engine's mechanical governor assembly, working alongside the governor arm and linkage to regulate engine speed by applying calibrated tension against centrifugal force. When the spring loses tension or breaks, the governor loses its ability to maintain a stable RPM set point, causing the engine to hunt, surge, or run uncontrolled. Replacing a fatigued or failed governor spring restores the balance between fuel delivery and load demand, keeping engine speed consistent throughout the finishing pass.
