Description
This 216 page, Massey Ferguson service manual is a reproduction of the original manual in condensed form covering MF340, MF350, MF355, MF360, and MF399 diesel tractors. It provides the full detail technicians and owners need: system theory, diagnostics, disassembly & assembly instructions, torque specs, schematics, and maintenance charts.
This manual is intended for serious repair work and will guide you through common and complex tasks including engine rebuilds (crankshaft, pistons, connecting rods, camshaft), hydraulic and transmission service, steering, axle and differential adjustments, PTO and clutch systems, and electrical diagnostics. Whether you’re doing routine maintenance or restoring a tractor, you’ll find step-by-step procedures, fault-finding charts, wiring diagrams, and more.
Common repairs on these MF series tractors often involve head gasket replacement, fuel injection pump calibration, clutch overhaul, hydraulic leaks, or differential gear adjustments. With the guidance from this manual, you can confidently bench-rebuild cylinders or calibrate the fuel injection system using factory tolerances.
Key features include:
– Full specifications (torque, capacities, tolerances)
– System theory and operation explanations
– Disassembly & assembly instructions for all major assemblies
– Wiring diagrams, hydraulic schematics, and control layouts
– Maintenance schedules and lubrication charts
– Troubleshooting, test procedures, and visual inspections
