1965–1974 Ford 4400 3-Cylinder Utility Tractor Parts Catalog

This illustrated parts catalog covers the 1965–1974 Ford 4400 3-cylinder utility tractor, with shared Ford-series figures and application notes for different engine, transmission and market configurations.

Figure search and navigation: The index, headings and parts tables contain searchable PDF text. Bookmarks link to the index, catalog and reference appendices, with figure codes used to locate individual assemblies. Callouts embedded in drawings are not searchable; small illustration labels benefit from zooming.

• Engine components: Exploded views and parts tables for gasoline/LPG and diesel cylinder heads, blocks, crankshafts, pistons, valve gear, lubrication components and overhaul kits.

• Fuel and cooling: CAV injection pump, Holley and Zenith carburetors, LPG equipment, diesel cold-start kits, radiator assemblies and water-pump components.

• Transmissions and PTO: Select-O-Speed, dual-range and manual reversing assemblies, with clutch components, independent power take-off assemblies and torque-converter filter and cooler-tube listings.

• Steering and hydraulics: Power-steering pumps and cylinders, hydraulic lift assemblies, flow-control valves, remote-control valves, pipework and coupling kits.

• Axles and brakes: Front and rear wheel assemblies, rear axle and differential components, differential-lock linkage, center housing, brake controls and trailer brake kits.

• Electrical equipment: NHNA and NH-E electrical parts illustrations, starter and generator assemblies, lighting equipment, wiring harnesses and instrument-cluster components.

Suited to owners and mechanics who can identify their tractor’s installed assemblies and interpret application notes when selecting repair parts.

Parts Identification and 4400 Fitment

Parts tables pair figure references with part numbers, required quantities, application dates and replacement notes. Shared pages also contain entries for other Ford models, so each listing’s model restrictions matter.

The front-axle and steering section separates center-arm shafts and related hardware before and from S/N 6E9B. That distinction helps identify the correct version before ordering repair parts.

Engine, Fuel and Cooling Assemblies

Cylinder-head and block entries identify required gasket combinations when replacement castings are used. Piston and engine overhaul kit tables distinguish standard and oversize parts, with complete-set replacement notes for certain diesel piston updates.

Holley carburetor and CAV fuel injection pump exploded views show internal components. Carburetor repair-kit listings, Zenith carburetor tables and LPG fuel-lock, filter and vaporizer-regulator assemblies provide further parts detail.

Diesel air-cleaner pages distinguish oil-bath and dry-type units. Radiator and water-pump sections identify hoses, clamps, fans, belts and thermostats by application.

Transmission, PTO and Hydraulic Parts

Select-O-Speed drawings break out planetary carriers, brake bands, clutches, the control selector and transmission control valve. Separate layouts cover dual-range 7-speed (Germany) and 8-speed gearboxes, manual reversing transmissions and independent PTO assemblies.

Torque-converter coverage is limited to filter and cooler-tube components, rather than internal converter overhaul.

Hydraulic pump listings distinguish piston-type and gear-type assemblies. Lift-cover and lift-cylinder drawings identify control components, seals and linkage, while remote-control-valve illustrations show the individual valve parts and associated kits.

The flow-control tables specify color-matched plungers and housings. Earlier gear-type pump entries identify a cover, coupling and drive gear that require replacement as a set, helping avoid mixing incompatible component versions.

Chassis and Electrical Equipment

Front-end wafer weights, steering gears and power-steering cylinders have their own illustrated parts breakdowns. Other sections document automatic pickup hitches, rollbar safety frames, seats and sheet-metal components.

Electrical System LH/RH and Rear Lamps, Flasher & Wiring illustrations show harness and component locations for NHNA and NH-E applications. Starter, generator and instrument-cluster tables identify electrical repair parts. These are component layouts, not complete diagnostic wiring schematics.

Parts Reference and Repair Limits

This catalog supports parts identification and repair planning. It does not provide step-by-step repair or diagnostic procedures, torque tables or complete overhaul instructions.

The hardware-conversion appendix distinguishes clearance-hole substitutions from metric/inch threaded connections. Mixing thread types risks damage to nuts, studs and tapped holes.

Use the appropriate service manual for safety procedures involving heavy tractor assemblies, raised equipment or hydraulic pressure.

Printable PDF and Included Reference Pages

Supplied as one printable, English-language 620-page PDF: 597 catalog pages, four figure-index pages and 16 reference pages covering abbreviations and metric/inch hardware conversions, plus one search-help page, one introductory page and one blank page. All are included in the total.
