Massey Ferguson MF35 Tractor 1960–65 Workshop Service Manual

This Massey-Ferguson 35 Tractor Workshop Service Manual covers workshop-level service and repair of MF35/FE-35 Standard/basic and De-Luxe tractors.

Text Search, Bookmarks, and Wiring Detail

Search and diagram detail: The workshop manual has OCR text search and section bookmarks, although recognition errors can affect searches and the headlamp illustration has no searchable text. The separate wiring sheet has neither text search nor bookmarks. Small wiring labels in the checked diagrams are readable when enlarged.

The English ZIP download contains two printable PDFs totaling 384 pages: the 383-page workshop manual, including one additional front cover, and a separate one-page wiring sheet. That sheet reproduces the carburetor- and diesel-engine diagrams on PDF p. 177 of the workshop manual.

Engine Overhaul, Multi-Power, and Ferguson Hydraulics

These are selected repair topics, rather than a complete contents list. Further subjects include mechanical-governor operation and seat, hood, and fender service.

• Diesel engine repair: Step-by-step engine removal, cylinder-head and bottom-end overhaul, timing-system service, and dimensional inspection for the 23C and 3-A-152.

• Fuel and cooling: Carburetor adjustment, diesel injection timing and bleeding, injector testing, thermostat checks, and water-pump service.

• Clutch and transmission: Single- and dual-clutch repair, tractor splitting, standard transmission overhaul, and Multi-Power clutch, pump, pressure-test, and fault-finding procedures.

• Ferguson hydraulics: Draft, position, and response control; control-valve diagnosis; lift-cover, ram-cylinder, and pump repair; and linkage adjustment.

• Rear axle and P.T.O.: Differential-lock and non-lock axle procedures, bearing and pinion setup, and P.T.O. shaft, bearing, sleeve, and seal service.

• Steering and brakes: Steering-box overhaul, front-axle and hub service, and mechanical, dual-hydraulic, and dual-mechanical brake repair.

• Electrical diagnosis: Dynamo, starter, ignition, and control-box service, supported by engine-specific wiring diagrams and lighting-harness views.

Suited to mechanics and experienced owners equipped for tractor splitting, precision measurement, and hydraulic pressure testing.

Engine Repair and Variant Limits

The engine sections are divided by actual engine design. The 3-A-152 diesel material covers cylinder-head repair, lubrication, timing gears, pistons and connecting rods, cylinder liners, crankshaft and main bearings, flywheel and ring gear work, and dimensional inspection.

The 23C diesel section has its own overhaul coverage, including the oil pump, valve seats and guides, Ricardo swirl chambers, timing chain and hydraulic tensioner, injector-pump drive housing, pistons, liners, crankshaft, and rear oil seal. Internal engine-overhaul chapters cover these diesels; the 87 mm petrol, V.O., and L.O. material provides specifications plus fuel, ignition, and cooling-system information.

Variant coverage: The general specifications identify Vineyard and Industrial chassis codes and refer their additional data to Section T. That dedicated section is not included. The file runs through Section R, Seat, Hood and Fenders; Section U, Service Tools and Equipment, is also absent, although tool references appear throughout the repair procedures.

Fuel Systems, Cooling, and Original Electrics

Fuel equipment: Zenith 28G carburetor information distinguishes petrol, V.O., and L.O. applications. Diesel coverage includes C.A.V. D.P.A. injection-pump operation, removal and timing, fuel-lift-pump service, injector and Pintaux-nozzle testing, system bleeding, and Thermostart equipment.

Cooling: Radiator removal, temperature-gauge checks, thermostat testing, water-pump dismantling and assembly, and a cooling-system fault chart are included. Separate water-pump procedures address the different diesel engine designs.

Electrical components: Repair data covers the original dynamo system. The C39P-2 dynamo is identified as Part No. 22259, with separate M45G diesel and M35G carburetor-engine starter specifications. Distributor settings distinguish petrol, V.O., and L.O. applications and document engine-number changes.

Hydraulic Controls and Transmission Repair

The Ferguson hydraulic section explains overload release, external pressure take-off, the oscillating control valve, control spring, ram cylinder, and lift-cover linkage. Its fault table connects symptoms such as failure to raise, failure to lower, and uneven lift with checks of valves, leakage, and control adjustment.

Serial-specific pump and lift data help match specifications to the tractor before teardown. The separate single- and dual-clutch transmission views also distinguish the drive arrangements for the hydraulic pump and P.T.O.

The standard transmission combines sliding-spur gears with a planetary dual-range unit. De-Luxe dual-clutch tractors have a separate hydraulic-pump and P.T.O. drive path. Multi-Power coverage extends to the hydraulic multi-plate clutch, freewheel, gear pump, control valve, linkage, complete dismantling and reassembly, and fault finding.

Axles, Steering, and Brake Configurations

Rear-axle procedures cover differential and pinion setup, including tractors with a differential lock. P.T.O. material distinguishes engine-speed, ground-speed, and live operation alongside bearing, sleeve, and oil-seal replacement.

Steering instructions distinguish access arrangements before and after February 1959. Brake documentation separates the hydraulic arrangement used before March 1961 from the later duo-servo design, with wheel-cylinder, master-cylinder, bleeding, adjustment, and dual-mechanical brake procedures.

Workshop Tools, Reference Views, and Repair Cautions

Tool callouts include the MF.27 Tractor Dismantling Stand, MF.165 Front Axle Wedge Tool, MF.226 lift-cover support tool, MF.260 with MF.260-1 adaptor for Multi-Power pressure testing, MF.159 clutch centralizer, and MF.220 Lever Fulcrum Height Setting Gauge.

Reference illustrations include the carburetor- and diesel-engine wiring diagrams, General View of Multi-Power Transmission, Exploded View of Hydraulic Clutch, Hydraulic Pump Cut Away to Show the Control Valve Assembly, and Sectional View of Steering Box. System-specific fault tables support clutch, Multi-Power, cooling, fuel-system, and hydraulic diagnosis.

The 23C timing section identifies piston-to-valve contact as a damage risk when the timing chain is removed. Multi-Power procedures flag vulnerable cast-iron sealing rings, while rear-axle work identifies housing oil-seal damage and loss of the shim pack that establishes axle-shaft end float.

Tractor splitting, heavy component handling, hydraulic pressure testing, brake work, and rotating machinery require proper workshop support, isolation, and lifting practices.

A Preview of Hydraulic Pump and Multi-Power Test Data

For tractors from serial 65685, the hydraulic-pump specifications give a .915-inch bore and minimum delivery of 3.333 Imperial gallons per minute at 1,500 psi and 720 pump rpm, equivalent to 2,000 engine rpm, with oil viscosity no greater than 250 S.U.S.

The hydraulic relief valve has a nominal setting of 2,500 psi. Its test data specify an opening threshold of at least 2,300 psi and a maximum of 2,800 psi while bypassing 2 Imperial gallons per minute, using SAE 50 oil at 110–140°F.

Maximum lower-link lift from the lowest position is listed as 1,500 lb through tractor serial 65684 and 2,500 lb from 65685. These figures describe maximum lift from that position, rather than recommended field or road-transport loads.

Multi-Power checks specify 150 psi operating pressure and 260–300 psi pump relief-valve pressure, both at 1,500 engine rpm.
