• Covers 1975–1982 Massey Ferguson MF550, MF560, MF565, MF575, and MF590 tractors (8-speed and Multi-Power drivetrains)
• Official OEM publication 1856 072 M2 (Issue 1 and 2)
• 619 pages of mechanical specifications, troubleshooting procedures, and system diagrams
• 12 detailed wiring and circuit schematics
• Definitive factory reference for overhauling Perkins AD3.152, A4.236, and AD4.203 engine families

Technical Documentation and System Coverage

This workshop manual organizes maintenance data for the MF550 through MF590 line into ten primary sections. It starts with general specifications and operating parameters. Then it gets into the heavy lifting. You will find deep-dive overhaul procedures for the Perkins 3-cylinder and 4-cylinder engines, alongside their cooling, fuel injection, and air filtration systems. The powertrain chapters map out the dual-clutch assemblies, 8-speed and Multi-Power transmissions, rear axles, and independent power take-off (PTO) servicing.

Additional sections break down the hydraulic systems. This includes precise settings for the scotch yoke pump and relief valves. Steering components and front axle configurations are also fully documented. The final chapters detail the cab assembly, interior trim, heater systems, and electrical routing. Exploded-view diagrams show the exact tool placements needed for professional-grade disassembly and assembly tasks.

Specification Highlights

Proper calibration is critical for these tractors. Engine timing for the MF550 is specified at 16° B.T.D.C., while the MF565, MF575, and MF590 require a 23° B.T.D.C. setting. You get exact figures for critical component fastening, such as the rear axle hub nut torque listed at 115 N·m (85 lbf·ft). The manual documents hydraulic system relief valve pressure at 20.7 N/mm² (3000 lbf/in²) for the MF565 and MF575 models. Fluid capacities are clearly charted, noting the Multi-Power system's 32-liter capacity and the 98-liter fuel tank on the MF575.

Working with high-pressure hydraulics, heavy drivetrain components, and precise torque specifications carries inherent risks, so always ensure the tractor is properly supported and system pressure is safely relieved before starting any teardown.
