Description

If your trusty MF 135 has started making more noise than usual, running rough at idle, or the valve adjustments just won’t hold anymore, your rocker shaft assembly is probably telling you it’s time for a replacement. This is the heart of your valve train system—the part that operates every intake and exhaust valve to keep that reliable three-cylinder Perkins engine breathing properly. When it wears out, you’ll know it.

What You’re Getting

Complete assembly with rocker shaft, rocker arms, bushings, and all hardware—no hunting for extra parts
Precision-machined components that restore smooth valve operation throughout your engine’s RPM range
Heavy-duty construction built to handle the constant stress of farm work and thousands of valve cycles per minute
Direct OEM replacement design that fits perfectly with your existing valve train components
Quality materials that resist wear and maintain proper valve clearances for the long haul

Built for Real Farm Work

The Massey Ferguson 135 became legendary for its simple mechanical construction and exceptional reliability, making it ideal for family farms where dependable performance was crucial. These reliable 45-horsepower tractors were the backbone of small to medium-scale farming operations worldwide, excelling at diverse tasks including cultivation, planting, hay making, and general farm maintenance. Whether you’re bush hogging pastures, running a hay baler, or handling daily chores with a loader, your engine needs precise valve timing to maintain the power and efficiency that keeps your 135 working productively day after day.

Made to Last

The valve train works harder than just about any other part of your engine, with rocker arms constantly pivoting to operate valves thousands of times per minute. This complete assembly handles those demanding cycles while maintaining the precise tolerances needed for proper valve operation. Quality construction ensures consistent valve clearances, protecting your expensive valves and valve seats from damage caused by improper operation.

Good to Know

This complete assembly simplifies installation since you get everything needed in one package rather than ordering individual components. Installation requires removing the rocker cover and old assembly, then installing the new complete unit and adjusting valve clearances to specification. While this job requires mechanical knowledge and proper tools, many experienced farmers handle it themselves. Make sure to follow proper valve adjustment procedures and use fresh engine oil after installation.
