Description

When your engine starts making that telltale valve tap or losing compression on startup, worn valve springs are often the culprit. This exhaust valve outer spring is a critical component that keeps your valves sealing tight and opening at just the right time. If you’ve noticed rough idling, loss of power, or blue smoke on startup, it might be time to check those valve springs while the head’s accessible.

What You’re Getting

Precise spring tension designed for exhaust valve operation under extreme heat
Heavy-duty construction that handles the constant compression cycles
Outer spring design that works with your existing valve train components
Direct replacement that matches original specifications

Built for Real Farm Work

This spring fits a wide range of Massey Ferguson tractors powered by Perkins engines, from the smaller 300 series utility models up through the big 8000 series row-crop machines. Whether you’re running a 3635 on hay ground or pulling heavy implements with an 8140, proper valve spring tension keeps your engine breathing right and making full power when you need it most.

Made to Last

Farm engines work hard, and valve springs take a beating from heat, constant motion, and pressure cycles. This spring uses quality steel that maintains proper tension through temperature extremes and thousands of operating hours. The outer spring design distributes load evenly and provides backup support if the inner spring fails.

Good to Know

Valve spring replacement is cylinder head work that requires proper tools and experience. If you’re doing a head rebuild, it’s smart to replace all valve springs as a set since they wear together. Check spring free length and installed height against specifications – improper valve geometry causes premature wear and poor performance.
