Description

When you notice uneven engine operation, loss of power under load, or compression issues on your MF 5400 or 6400 series tractor, weak or broken valve springs could be the culprit. These critical engine components keep the intake and exhaust valves sealed tight against their seats, maintaining proper compression and timing that your diesel engine needs to deliver full power when you’re pulling heavy implements or working long days.

What You’re Getting

Precision-manufactured spring steel construction that maintains consistent tension over thousands of cycles
Proper spring rate engineered to match your engine’s valve timing and compression requirements
Heat-treated material that resists fatigue and maintains strength under continuous operation
Direct replacement design that fits your 1104C engine without modifications

Built for Real Farm Work

This valve spring fits the reliable 1104C engines found in your MF 5400 series utility tractors and 6400 series row-crop machines. Whether you’re running a 5425 on hay ground, pulling a planter with your 5455, or handling loader work with a 6445, these engines depend on proper valve sealing to maintain the power and fuel efficiency you need for productive farming.

Made to Last

Farm engines work hard in dusty, demanding conditions, and valve springs are constantly opening and closing thousands of times per hour. This spring is built from quality steel with the proper heat treatment to handle continuous operation without losing tension or breaking when you need your tractor most.

Good to Know

Valve spring replacement requires engine disassembly and valve access, so it’s typically done during major engine service or head work. If you’re doing valve work, it’s smart to replace all the springs at once rather than waiting for individual failures. Keep your engine running smooth and strong with proper valve train components.
