PDF Access, Wiring Detail, and Page Count

Search, bookmarks, and diagram detail: The manual content is not searchable. Embedded bookmarks provide access to major sections, but Part 11 has no dedicated bookmark. Small component labels, terminal numbers, and wire-color codes in the electrical diagrams require zooming for comfortable reading.

One printable, 619-page PDF, including one added cover and 21 blank pages. Introductory material and Parts 1–10 occupy PDF pp. 2–575; the 44-page Part 11, Special Models / Four Wheel Drive, occupies PDF pp. 576–619.

Engine, Driveline, and Tractor-System Repair

The following selected repair topics illustrate the coverage rather than reproduce the full contents. Other sections include pre-delivery inspections, storage preparation, and return-to-work checks.

• Perkins engines: Step-by-step internal repair for AD3.152, AD4.203, A4.236, and A4.248 engines, supported by fault charts and cooling-system service.

• Clutches and transmissions: Dual and split-torque clutch service, 8-speed gearbox overhaul, Multi-Power repair, and separate Mk II constant-mesh and synchromesh procedures.

• Rear axle, brakes, and PTO: Differential setup, epicyclic final-drive repair, brake service, differential-lock adjustment, and live, ground-speed, and independent PTO arrangements.

• Hydraulics and steering: Ferguson lift adjustments, pump and valve repair, auxiliary/Multi-Power/I.P.T.O. pressure and flow tests, steering bleeding, and component overhaul.

• Electrical circuits: Two wiring diagrams with component and color-code keys, fuse layouts, battery testing, and removal procedures for electrical equipment.

• Cab and body: Sheet-metal and cab removal, seat and door service, window-glass and seal replacement, plus heater, blower, and ventilation-component repair.

• Four-wheel drive: Category II and III front-axle overhaul, planetary reductions, universal joints, differential adjustment, transfer-gearbox repair, and hydraulic-clutch testing.

Written for Massey Ferguson dealers and distributors, this manual suits workshop technicians equipped for tractor splitting, precision measurements, and the specified special-tool operations.

Engine Overhaul, Cooling, and Fuel-System Limits

Engine work extends to valve seats and guides, camshafts and tappets, pistons and connecting rods, cylinder liners, and crankshaft thrust washers. Separate procedures address timing gears, flywheels and ring gears, rear-main seals, oil pumps, and the balancer unit.

The AD3.152 cylinder-head diagrams distinguish the early and late engine serial groups. This allows the applicable tightening sequence to be identified before reassembly. Liner-service cautions explain how burrs or handling damage can distort a liner after installation.

Maintenance schedules accompany the repair material. Cooling coverage includes overheating diagnosis, radiator work, thermostat testing, and water-pump service.

Fuel-system procedures address the dry-element air cleaner, tank and sender, Thermostart, lift pump, filters, injector removal, injection-pump removal, de-aeration, and static timing. Pump-setting-code tables accompany the timing procedures. Detailed fuel-injection component servicing requires the separate Perkins and CAV workshop manuals.

Tractor Splitting and Driveline Variations

Splitting procedures distinguish MF550/MF560 support arrangements from MF565/MF575/MF590 layouts. They cover front-axle/engine and engine/transmission separation, plus the applicable transmission/spacer or spacer/center-housing separation and withdrawal arrangements.

Internal gearbox work includes selector rails, clutch-release mechanisms, input and PTO shafts, mainshafts, reverse clusters, bearings, and seals. Multi-Power sections cover the clutch unit and spool valve; the Mk II synchromesh section includes cone-assembly service.

Rear-axle procedures distinguish standard-flow and high-flow pump installations where pinion, bearing, or PTO arrangements differ. Brake coverage includes actuator and friction-component service, adjustment, and balancing.

Reassembly cautions explain the transmission and main-drive damage caused by forcing misaligned housings together. Clutch inspection also addresses the loss of heat-dissipation performance caused by skimming false flywheels or pressure plates.

Lift Controls, Steering, and Auxiliary Equipment

Ferguson-system coverage includes lift-cover, ram-cylinder, response-control, and pressure-control work, with internal and external adjustment procedures. Hydraulic tests separate auxiliary-pump, Multi-Power, I.P.T.O., and pressure-maintaining-valve checks.

Two-wheel-drive axle sections cover track and toe-in adjustment, hubs, spindle shafts and housings, beams, and supports. Steering procedures distinguish Plessey and Aeroquip pumps and include cylinder and hand-pump service.

Accessory instructions cover automatic hitches, drawbars, stabilizers, assistor rams, Kontak spool-valve kits, PTO belt pulleys, weights, and trailer hydraulic brakes. Cab detail extends to plenum components, recirculation controls, heater plumbing, and windshield demister ducts.

Workshop Drawings, Test Data, and Tools

Illustrations include engine timing-gear alignment drawings, dual-clutch sections, Ferguson pump/control-valve exploded views, rear-axle/PTO assemblies, and four-wheel-drive axle and transfer-gearbox views. The electrical diagrams separate starting, charging, gauges, and warning circuits from lighting, indicators, hazards, and the trailer socket.

Reference data includes tightening sequences, clearances, wear limits, installed-liner dimensions, bearing preload, gear backlash, fluid capacities, and hydraulic test specifications. Engine and clutch fault charts are supplemented by wheel-and-tire fault finding.

Tool references include the PD.150 liner remover/replacer, MF.159A clutch centralizer, MF.215 PTO clutch setting gauge, MF.314 lever-height gauge, and MF.810-series test adapters. Dimensioned seat-replacer and peening-tool drawings support Multi-Power relief-valve seat service.

Tractor splitting, cab removal, axle work, and hydraulic testing require suitable lifting and support equipment, electrical isolation, and pressure-relief precautions.

Sample Liner, Crankshaft, and 4WD Clutch Specifications

For the MF550’s AD3.152 engine, the liner section specifies a fully seated liner top face between 0.000 and 0.15 mm below the cylinder-block face. The crankshaft section gives an end-float range of 0.050–0.380 mm for thrust-washer inspection.

The four-wheel-drive hydraulic-clutch test specifies 0.90–1.04 N/mm² (130–150 psi) with the clutch engaged, the engine at 1000 rpm, and transmission oil at 50°C.
