Description

Your tractor engine runs thousands of cycles every minute, and those exhaust valves take a beating. When valve springs start losing their tension, you’ll notice rough idling, power loss, and eventually expensive engine damage. This inner valve spring keeps your exhaust valve seating properly, ensuring clean combustion and protecting your investment in your Massey Ferguson or Landini tractor.

What You’re Getting

Precise spring tension engineered to match original equipment specifications
Heat-treated steel construction that maintains strength through countless heat cycles
Inner spring design works with the outer spring to provide consistent valve control
Direct replacement that fits without modifications or special tools
OEM quality construction built to handle the demands of farm work

Built for Real Farm Work

This spring fits a wide range of Massey Ferguson tractors powered by Perkins A4.212, A4.236, and A4.248 engines, including popular models from the 200, 300, 3000, 3600, 4200, 6100, and 8100 series. These are the workhorses you see pulling plows, running balers, and powering PTO equipment across farms everywhere. Whether you’re running a compact 265 or a bigger 6180, proper valve operation keeps your engine running smooth and strong.

Made to Last

Engine valve springs operate in extreme conditions – high temperatures, constant compression cycles, and corrosive exhaust gases. This inner spring uses quality steel that’s heat-treated to maintain proper tension even after thousands of hours of operation. The precision manufacturing ensures consistent spring rate and proper valve timing, which translates to better fuel efficiency and longer engine life.

Good to Know

Valve spring replacement requires removing the cylinder head, so it’s typically done during major engine work or rebuilds. While you’re in there, it’s smart to replace both inner and outer springs together, along with valve seals and guides if needed. Always check valve clearances after installation – proper adjustment is critical for engine performance and longevity.
