Injector Pump Throttle Return Spring for Massey Ferguson 200 & 300 Series Tractors

Description

If your tractor’s throttle pedal feels loose, won’t return to idle properly, or the engine won’t shut down when you turn the key, a worn throttle return spring is likely the culprit. This small but crucial component ensures your injection pump’s throttle mechanism returns to the idle position when you release the pedal, giving you smooth control over engine speed and reliable shutdown.

What You’re Getting

• Direct replacement spring that restores proper throttle function and response
• Keeps your throttle mechanism operating smoothly for precise engine control
• Essential safety component that ensures reliable engine shutdown
• Prevents throttle from sticking in high-idle position during operation

Built for Real Farm Work

This spring fits Massey Ferguson 200 series tractors like the 240 and 250, plus a wide range of 300 series models from the 340 through 399. These versatile tractors are workhorses on farms everywhere, handling everything from cultivation and planting to loader work and general farm duties where precise throttle control is essential for safe operation.

Made to Last

Injection pump components work under constant tension and vibration, so this spring is built to handle the demands of daily farm use. The proper spring tension ensures your throttle lever returns quickly and consistently, season after season, without losing its snap-back action.

Good to Know

This is typically a straightforward replacement that connects to your injection pump’s throttle mechanism. When installing, make sure the spring hooks are properly seated and the throttle lever moves freely through its full range. A quick test run should show immediate improvement in throttle response and reliable return to idle.
