Multiquip 50355100 Governor Spring 2G40

The Multiquip 50355100 Governor Spring 2G40 is a genuine OEM component designed for RW1404MR and RW1504HF series RAMMAX walk-behind rollers. Sourced directly from Multiquip, this spring is an exact match to the original part installed at the factory, ensuring correct tension and governor response right out of the box. Verified fitment includes RW1404MR (all serial numbers), RW1404MR S/N 326075 and up, and RW1504HF up to S/N — always confirm your serial number range before ordering.

Key Features

• Genuine OEM Spring Tension — Manufactured to the exact load and rate specification of the original 2G40 governor spring, ensuring the governor responds correctly across the engine's RPM range.
• Direct Drop-In Replacement — Matches the original mounting points and spring geometry on the governor assembly, requiring no modification to fit.
• Confirmed Fitment — Compatible with RW1404MR (all S/N), RW1404MR S/N 326075 and up, and RW1504HF up to S/N 1534188 RAMMAX walk-behind rollers.
• Engine Speed Stability — A correctly tensioned governor spring keeps engine RPM stable under varying compaction loads, protecting both the engine and the roller's compaction output.
• Fuel System Safety Relevance — A failed or stretched governor spring can cause engine overspeed or hunting, creating a potential safety hazard during operation; replacing it promptly restores proper speed control.

The governor spring is a critical component in the engine's mechanical governor system. It works against the flyweights to hold the throttle at the operator-set position, maintaining consistent engine speed as the load on the machine changes during compaction passes. When the spring loses tension, stretches, or breaks, the engine may surge, hunt for RPM, or run uncontrolled — all of which compromise compaction quality and can accelerate engine wear. Replacing a worn or damaged governor spring with the correct OEM part restores stable, predictable engine speed and protects the roller from the effects of unregulated engine operation.
