Component and System Documentation

The Massey Ferguson MF255–MF290 shop manual documents the exacting service specifications for the Perkins engine family. This includes the AG4.212, AD4.203, A4.236, and A4.248 variants. You will find a detailed breakdown of the engine assembly, cylinder head, valve train, cooling system, and governor adjustments. It also thoroughly outlines the hydrostatic power steering system. Mechanics can review pump relief valve pressure settings alongside component diagrams for Parker-Hannifin, Sundstrand, and Aero-Quip pumps. Before beginning any major teardown, always verify that your heavy equipment is securely supported and hydraulic pressure is fully relieved to prevent severe injury.

The transmission section covers the 8-speed gear change as well as the Multi-Power transmission systems. It provides critical data for the pto input shaft, main output shaft, and range planetary units. Need rear axle data? Detailed specifications for the planetary final drive and both wet and dry braking systems are included. The text pays specific attention to bearing preloads and clearance settings for all axle components, giving you exactly what you need to plan a successful repair.
