Description

When your Massey Ferguson’s injection pump throttle isn’t returning properly or feels sluggish at the controls, a worn-out spring is often the culprit. This essential long-style spring keeps your pump’s throttle mechanism working smoothly, ensuring proper fuel control whether you’re idling in the farmyard or pulling hard in the field. Without it working right, you might notice erratic RPMs, poor throttle response, or that annoying tendency for the engine to hang at higher RPMs when you back off the throttle.

What You’re Getting

Precision-made spring designed to handle the constant cycling of throttle operation
Long configuration provides proper tension for reliable throttle return action
Built to withstand the vibration and temperature changes inside injection pump housings
Direct replacement that restores factory throttle feel and response

Built for Real Farm Work

This spring fits Massey Ferguson tractors equipped with CAV injection pumps – the reliable fuel delivery systems found on countless MF models from the classic 35 series up through various 100, 200, and 300 series machines. Whether you’re running a compact utility tractor for loader work or operating a mid-size row-crop machine for cultivation and planting, smooth throttle control makes all the difference in getting your work done efficiently.

Made to Last

Injection pump components work in a challenging environment with constant pressure cycles, fuel exposure, and engine vibration. This spring is manufactured from quality steel that maintains its tension and won’t fatigue prematurely. It’s built to handle thousands of throttle movements while keeping your fuel delivery system operating like it should.

Installation Notes

This spring installs inside the injection pump assembly, so you’ll need to access the pump internals during installation. If you’re comfortable working on injection systems, it’s a straightforward replacement once you have the pump apart. Consider replacing other internal springs and seals while you’ve got it open – it’s good preventive maintenance that saves time later.
