1975–1981 Ford 3600 3-Cylinder Tractor Parts Catalog

This illustrated parts catalog covers the 1975–1981 Ford 3600 3-cylinder all-purpose agricultural tractor, with gasoline and diesel listings. Other Ford models appear in shared component tables; applicability follows the model and configuration notes for each entry.

• Engine and fuel systems: Cylinder blocks, crankshafts, pistons, valves, Holley and Zenith carburetors, rotor fuel injection pumps, and injector component breakdowns.

• Transmissions and PTO: Illustrated parts lists for manual transmission variants, clutch controls, single and double clutch assemblies, and Power Take-Off components.

• Axles, brakes, and wheels: Front and rear axles, differential lock, FWD assemblies, wheel hardware, brake controls, and NH-E hydraulic trailer brakes.

• Hydraulics and steering: Lift assemblies, remote valves, engine-mounted piston and gear pumps, steering gears, cylinders, and power-steering pump reservoirs.

• Cooling and air intake: Radiator and water-pump assemblies, with separate component listings for oil-bath and dry air cleaners.

• Electrical and cab equipment: Wiring-harness layouts, instrument clusters, starting motors, alternators, ROPS safety frames, and tractor cab parts.

This catalog is suited to mechanics, parts-counter staff, and owners who can match illustrated reference numbers and application notes to the equipment fitted to their tractor.

Engine and Fuel-System Parts

Engine listings identify bearings, gasket kits and overhaul-kit contents alongside the major assemblies. Replacement-block application notes help check compatibility before ordering engine parts.

The Rotor Fuel Injection Pump and Holley Carburetor Assembly views identify internal components; the separate Zenith listing distinguishes its jets and repair kit. These are parts breakdowns, not pump-calibration instructions or step-by-step overhaul procedures.

The gasoline-piston section flags crankshaft/piston combinations that leave pistons projecting above the block, creating a risk of piston-to-head interference. The exploded view alone does not establish piston compatibility.

Transmission, PTO, and FWD Assemblies

Drivetrain coverage separates six-speed, dual-range eight-speed, and 6x4 manual reversing transmissions. The Dual Range 8 Speed Transmission views identify countershaft, sliding-coupling and gear components; clutch tables distinguish transmission PTO and live PTO arrangements.

FWD breakdowns cover drive shafts, differential boxes and reduction gears, with separate front-transfer-housing, collar-gear and wet-clutch transfer-box views. The double-clutch illustrations identify the PTO disc and its associated pressure-plate components.

Wheels, Steering, and Hydraulic Components

The wheel sections distinguish 16- and 19-inch front-wheel configurations and standard versus power-adjustable rear wheels. Steering tables identify relief valves, worm bearings and the worm-bearing locknut as replacement parts.

Hydraulic Lift Cylinder views distinguish cylinder, valve and spool components. Remote-control valves and engine-mounted pumps have separate breakdowns for identifying internal parts and repair kits.

Before major component work, verify support capacity and use properly rated heavy-duty jack stands.

Electrical Equipment and Cab Applications

Electrical System, NHNA and Cab Electrical System illustrations locate harnesses, switches, lamps and connectors. These are component-layout drawings, not complete circuit schematics or electrical fault-finding procedures.

Cab listings distinguish structures, glass, mounting parts and heating/air-conditioning assemblies. The NH-E rear-crossbar repair-kit entry specifies use before date code 8E05 and references cab S/N W.H. 34734. Installation instructions are referenced to separate Service Bulletin #9 (1980).

A Preview of Wheel Hardware and Steering-Cylinder Sizes

These examples are a small selection of the catalog's dimensions for identifying replacement parts.

The front-wheel hub bolt is specified as 1/2"-20 x 1-3/4", while the standard rear-wheel carriage bolt is 5/8"-18 x 2-53/64". These are hardware dimensions, not tightening specifications.

Steering-cylinder repair kits are distinguished by rod size: CAPN3301B for 1/2-inch rods and CAPN3301A for 5/8-inch rods. The cylinder listings caution against mixing different cylinder sizes on the same tractor.

PDF Search, Bookmarks, and Page Breakdown

Search and drawing detail: Index entries, figure headings and parts lists are searchable; illustration callouts are image content. Bookmarks lead to the search guide, index, catalog and reference appendices. Dense callouts benefit from zooming, and some long figure headings are clipped at the right edge.

Supplied as one printable, English-language, 697-page PDF. The total includes 673 pages of parts illustrations and lists, a five-page figure index, 16 reference pages, a one-page search guide, one additional front page and one blank page.
