Description

Your rocker shaft is one of those parts you don’t think about until it starts giving you trouble. When your engine starts making noise from the top end or you’re losing compression, a worn rocker shaft could be the culprit. This rocker shaft fits Massey Ferguson tractors with Perkins 4-cylinder engines including the 212 and 248 series, giving you the precision valve timing your engine needs to run smoothly and efficiently.

What You’re Getting

Precision-machined shaft that maintains proper valve clearances and timing
Hardened steel construction that resists wear from constant valve action
Proper oil passages that keep your rocker arms lubricated during operation
Direct OEM replacement that restores factory valve train geometry
Quality construction that handles the demands of diesel engine operation

Built for Real Farm Work

These tractors – from the reliable 165 and 188 models to the larger 290 and 390 series – are workhorses designed for demanding agricultural operations. Whether you’re running heavy implements during planting season, pulling through tough field conditions, or doing loader work around the farmyard, your valve train needs to operate precisely under all conditions. These machines excel in heavy fieldwork including deep plowing, disking, and cultivation, plus intensive hay operations and implement transport where reliable engine operation is essential.

Made to Last

Engine components take a beating from heat, pressure, and constant movement. This rocker shaft is built from quality steel with the proper heat treatment to handle thousands of cycles per minute. The oil passages are precisely drilled to ensure your rocker arms get the lubrication they need, and the surface finish is engineered to reduce friction and wear over the long haul.

Good to Know

Rocker shaft replacement requires removing the valve cover and rocker assembly – it’s a job that’s easier with the right tools and a clean workspace. While you’ve got things apart, it’s a good time to check your valve clearances and inspect the rocker arms for wear. A torque wrench is essential for proper reassembly to avoid warping the shaft or causing binding.
