Massey Ferguson 5400, 5425, 5435, 5445, 5455, 5460, 5465, 5470, 5475 Workshop Service Manual (P/N 3378545M5)

• Covers the 2004–2009 Massey Ferguson 5400 tractor line (models 5425 through 5475, including SA Orchard variants) across both 4-cylinder and 6-cylinder configurations.
• Official 2111-page AGCO workshop publication N° 3378545M5 (October 2007 edition).
• Contains detailed assembly diagrams, torque specifications, and system capacity reference tables for shop-floor use.
• Documents the GBA20 and GBA25 gearbox configurations, featuring comprehensive shimming procedures for front frames.

Manual Organization and Chapter Walkthrough

This 2111-page AGCO publication provides a thorough teardown and system analysis of the 5400 tractor series. It completely maps out mechanical disassembly and reassembly processes, skipping basic operator instructions to dive straight into front frame overhauls, engine-to-transmission coupling, clutching systems, and drivetrain component breakdowns. The documentation is structured modularly. It starts with general specifications and moves into heavy line work, including rear axle maintenance, power take-off systems, and complex hydraulic schematics. Electrical equipment troubleshooting charts are also included to help trace wiring faults quickly. Proper adherence to these factory procedures requires standard shop safety practices; always secure heavy components before breaking torque on frame mounts.

Technical Reference and Specification Highlights

The technical data sections cut out the guesswork for critical tolerances. Mechanics will find comprehensive tables covering engine performance baselines, transmission ratios, and track width adjustments. For example, cylinder head and main assembly torque values are categorized directly by bolt size and application. System capacities are highly specific: the cooling system for the 5465 model takes 25 liters, while the transmission oil volume for GBA25 Dyna 4 models requires a precise 69 liters. Front axle specifications call out the DANA AG 85 unit for the 5425 model. This level of granular data ensures that reassembly meets factory standards without relying on general rules of thumb.
