More Information About Massey Ferguson 4353773M91 Right and Left Hand Pair of Springs

The Massey Ferguson 4353773M91 Right and Left Hand Pair of Springs is a small kit with a big job. It is designed for the cooler box assembly used on many Massey Ferguson tractors. Because it includes both a right-hand spring and a left-hand spring, you get matched tension on both sides. As a result, the cooler box lid opens smoothly and closes securely.

Springs work under constant load. However, vibration, heat cycles, and regular opening can weaken them over time. Then the lid can feel heavy. It can also drop suddenly. In addition, a tired spring can let the cooler box rattle. That noise often turns into wear at the mounting points. Therefore, replacing the springs early helps protect the box, the hinge area, and nearby trim.

Right and left springs are not interchangeable. Instead, each spring is shaped and wound to suit its side. This matters because the lid must lift evenly. It also matters because uneven force can twist the hinge line. So, fitting the correct pair helps maintain alignment and consistent operation.

This replacement is made for agricultural conditions. So it suits dusty yards, exposure, and long working days. It is ideal for servicing, refurbishment, and accident repair. Likewise, it is a smart choice when you are fitting a new cooler box or rebuilding the existing one.

Installation is straightforward. First, confirm application by tractor model and serial number. Next, support the lid before removing the old springs. Then fit the right spring on the right side and the left spring on the left side. After that, check the lid action. Finally, make sure the box latches properly and sits flush.

Choose the Massey Ferguson 4353773M91 spring pair for smooth, balanced lift. It’s simple protection. Yet it helps keep your tractor tidy, quieter, and ready for work.
