Parts Catalog Breakdown

When you are trying to source the exact replacement part for a vintage Massey Ferguson, guesswork wastes time. This catalog breaks down every assembly and sub-assembly for the TO, TE, and TE-A lines. You get detailed exploded views showing exactly how the engine block, cylinder head, fuel system, electrical wiring, front axle, steering gear, and hydraulic controls fit together on the shop floor. Each diagram corresponds directly to reference tables listing the official part numbers, descriptions, and quantities required for both the 80 mm and 85 mm bore engine variants.

Component Specification Previews

Knowing the factory baselines speeds up the restoration process. These utility tractors feature a 203 cubic inch engine displacement. Field operation is supported by a 50-liter fuel tank. For fluid management, the engine sump requires 17 liters of oil, while the hydraulic system takes 22 liters for implement control. The rear axle drive utilizes a standard 4-forward, 1-reverse speed transmission, and the PTO operational speed hits a steady 540 RPM. Please remember that working on aging heavy machinery carries inherent risks. Always double-check fluid types and torque values against actual shop conditions, and ensure your workspace follows standard safety protocols before tearing down an engine or servicing hydraulics.
