Massey Ferguson MF35 Tractor 1960–65 Workshop Service Manual (MF35-WSM)

• 383-page Massey-Ferguson 35 Tractor Workshop Service Manual in PDF format, covering workshop-level service and repair data for MF35/FE-35 systems and assemblies.
• Directly covers Standard/basic and De-Luxe configurations, with separate technical material for the 87 mm petrol, vaporizing-oil (V.O.) and lamp-oil (L.O.) engines, the 23C diesel, and the 3-A-152 diesel. The opening specification section also identifies Vineyard and Industrial chassis codes.
• Documents production changes that matter when selecting procedures and specifications, including the hydraulic pump/lift change at tractor serial 65685, the steering-box access modification introduced after February 1959, and the revised dual-brake hydraulic arrangement introduced after March 1961.
• Covers the standard six-forward/two-reverse transmission and the Multi-Power system, which provides twelve forward and four reverse ratios and includes hydraulic clutch, pump, linkage, pressure-test, and fault-finding data.

Engine and Chassis Documentation

The engine sections are divided by actual engine design rather than treating every MF35 power unit as interchangeable. 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. Carburetor-engine information extends to 87 mm petrol, V.O., and L.O. ignition and fuel-system specifications.

Factory data goes well beyond general tune-up figures. The manual gives journal diameters, bearing clearances, ring gaps, valve and timing settings, cooling-system capacities, tightening torques, and component test limits. Electrical repair data is based on the original dynamo system rather than an alternator: the C39P-2 dynamo is identified as Part No. 22259, while separate M45G and M35G starter specifications are provided for diesel and carburetor tractors. Carburetor-engine distributor settings are also split by petrol, V.O., and L.O. applications, with engine-number change points where timing specifications were revised.

Hydraulic and Transmission Specifications

The Ferguson hydraulic system section covers draft control, position control, response control, overload release, external pressure take-off, the control-valve mechanism, lift cover, ram cylinder, control spring, pump removal and overhaul, linkage adjustment, and a hydraulic fault table. A major serial break occurs between tractors up to No. 65684 and No. 65685 onward. The later pump uses a .915-inch bore and is specified for a minimum delivery of 3.333 Imperial gallons per minute at 1,500 psi and 720 pump rpm. Hydraulic-system relief pressure is nominally 2,500 psi; test limits call for the valve to begin opening at no less than 2,300 psi and not exceed 2,800 psi while bypassing 2 Imperial gallons per minute. Lower-link lift capacity from the lowest position changes from 1,500 lb on early tractors to 2,500 lb on later tractors.

The standard transmission is a three-forward/one-reverse sliding-spur unit compounded by a planetary dual-range set, producing six forward and two reverse speeds. De-Luxe dual-clutch tractors use a separate drive path for the hydraulic pump and P.T.O. Multi-Power receives its own repair chapter: the hydraulic multi-plate clutch, freewheel, gear pump, control valve, linkage adjustment, complete transmission dismantling/reassembly, and fault finding are all covered. Factory pressure checks specify 150 psi Multi-Power operating pressure and 260-300 psi pump relief-valve pressure at 1,500 engine rpm.

Factory Repair Procedures and Reference Views

Shop-level procedures include engine removal, cylinder-head and bottom-end overhaul, clutch dismantling and adjustment, splitting the tractor at the engine/transmission and transmission/center-housing joints, Multi-Power clutch and pump repair, differential and rear-axle setup, hydraulic lift-cover and pump work, P.T.O. bearing and seal service, steering-box overhaul, front-axle service, and mechanical/dual-brake repair. 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.

Representative factory views 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.” These are backed by system-specific fault tables for the clutch, Multi-Power transmission, cooling system, hydraulics, and other assemblies.

Several manual-specific repair cautions are worth noting. During 23C valve-timing work, the crankshaft must be positioned away from T.D.C. while the timing chain is off because the small piston-to-valve clearance can allow serious contact damage. Multi-Power transmission work requires care around the cast-iron sealing rings during main-drive-shaft retainer removal and installation. Rear-axle procedures also warn against damaging the housing oil seal or losing the original shim pack, since those shims establish axle-shaft end float.

The PDF runs through Section R, Seat, Hood and Fenders. The front contents references a dedicated Section T for additional tractor-variant data and Section U for Service Tools and Equipment; those dedicated sections are not part of this file, although tool numbers are specified throughout the repair procedures. Tractor splitting, heavy component handling, hydraulic pressure testing, brake work, and rotating machinery require proper workshop support, isolation, and lifting practices.
