1956–1964 Massey-Ferguson 35 Tractor Workshop Service Manual

This English workshop service manual for the 1956–1964 Massey-Ferguson 35 tractor combines component specifications, repair procedures and fault tables. It uses both MF 35 and FE-35 designations and distinguishes Standard and De Luxe equipment.

• Engine coverage: Internal repair procedures for the 23C and 3-A-152 diesels, plus specification data for the petrol, V.O. and L.O. engines.

• Fuel and cooling: Zenith carburetors, CAV DPA injection-pump installation and timing, injector testing, governor operation, water-pump overhaul and thermostat checks.

• Clutch and transmission: Single and dual clutches, conventional gearbox and epicyclic reduction assemblies, Multi-Power components, pressure testing and fault diagnosis.

• Hydraulics and PTO: Pump overhaul, control-valve operation, draft and position control, lift linkage, and engine-speed, ground-speed and live power take-off arrangements.

• Electrical and lighting: Generator, starter, distributor and regulator servicing, starting interlocks, cold-weather heater plugs, lighting circuits and harness routing.

• Axles, brakes and bodywork: Rear axle and differential lock, steering box, front hubs, independent and dual brake systems, seats, hood and fenders.

The overhaul sections are suited to experienced tractor technicians and restorers with workshop equipment. Engine removal, machining and tractor splitting assume suitable stands, lifting equipment and special service tools.

Diesel Engine Repair and Variant Coverage

Internal engine work: The diesel chapters cover cylinder heads, valve seats, liners, pistons, connecting rods, crankshafts and lubrication systems. They include wrist-pin bush reaming, valve-timing checks and the 23C timing chain with its hydraulic tensioner; the Ricardo Comet swirl-chamber section drawing explains the combustion-head layout.

Machining and assembly: Tool references include the P.D.50C liner extractor and MF6200A fixture with MF6200AD reamers. For the 3-A-152, burrs can distort pressed-in liners; the 23C instructions warn of piston-to-valve damage if the engine is turned with tappet adjusters insufficiently backed off during reassembly.

Coverage limits: Petrol, V.O. and L.O. engines receive specifications and supporting-system coverage, but their internal overhaul chapters are not included. Separate Vineyard and Industrial specifications referenced as Section T are also outside this file.

The scan omits specification sheet B.12 and engine sheet C.122, leaving a gap between the 23C wrist-pin bush work and injection-pump drive dismantling. The separately indexed service-tool section U is absent, although individual procedures identify the required tools.

Fuel Equipment and Cooling Diagnosis

Carburetion and injection: Zenith carburetor sections provide dismantling, adjustment and fault tables. Diesel coverage explains DPA pump operation, installation timing and injector testing, while referring internal injection-pump adjustments to CAV specialists.

Cooling faults: Water-pump service procedures distinguish the engine installations. Thermostat checks and the overheating fault table connect cooling complaints with components requiring inspection.

Clutches, Multi-Power and Rear Axle Work

Drive engagement: Separate clutch procedures address single and dual arrangements, including the Auburn assembly used with the 3-A-152. Adjustment information links clutch release to transmission and PTO behavior.

Multi-Power diagnosis: The transmission section covers the hydraulic clutch, freewheel and control valve, with pressure-test arrangements using MF.260 and adaptor MF.260-1. Its fault table separates low oil pressure, clutch slip and overheating, helping direct diagnosis before further dismantling.

Final drive: Rear-axle procedures include bearing preload, axle-shaft endplay and differential-lock assembly. The exploded differential-lock illustration identifies the coupler, shifter fork, cam and bearing arrangement.

Hydraulic Lift, Steering and Brakes

Lift control: Pump cutaways show the control valve and internal oil passages, supported by draft, position and response-control explanations. The hydraulic fault table distinguishes linkage maladjustment from sticking valves and leakage, helping identify the relevant adjustment or repair.

Chassis servicing: Steering-box rebuilds, front-hub bearing work and axle-bush replacement accompany brake adjustment and overhaul procedures. The brake section distinguishes conventional mechanical brakes, combined mechanical/hydraulic units and dual mechanical systems.

Servicing heavy agricultural equipment involves substantial loads and pressurized hydraulics. Follow workshop safety procedures and use qualified assistance for major structural or internal machinery repairs.

Electrical Tests and Wiring References

Charging-system tests accompany generator and regulator service, while starter and ignition sections cover their respective components. Heater-plug and lighting-harness diagrams show circuit connections and cable-color identification for tracing electrical faults.

Selected Valve-Clearance and Multi-Power Test Data

A small selection illustrates the manual’s adjustment and test data. For the 23C diesel, cold valve-tip clearance is 0.012 in (0.305 mm) at the intake and 0.008 in (0.203 mm) at the exhaust.

The Multi-Power control-valve test specifies clutch oil delivery pressure of 150 psi (10.55 kg/cm²) with the engine running at 1,500 rpm.

PDF Navigation and Scan Detail

Text search and diagram viewing: The scan has no searchable text layer. Seventeen bookmarks provide access to the start and major sections; small wiring labels are readable with enlargement, while some page-edge characters are clipped and photographs vary in clarity.

The download consists of one printable English PDF totaling 383 pages. This total includes one cover sheet and one additional copy of sheet C.121, as well as the section dividers and indexes.
