Ford 2600 Tractor Parts Catalog 1975–1981

This Ford 2600 tractor parts catalog covers the 1975–1981 all-purpose model, with gasoline and diesel engine listings and variant-specific parts entries. Shared illustrations also name the 3600, 4100, 4600, 5600, 6600, and 7600; parts applicability follows the individual figure and table entry. This is a parts-identification reference, not a step-by-step repair manual.

Searchable Parts Tables and Figure Navigation

Search and illustration detail: Figure headings and parts tables support text search, while many reference numbers within drawings are not searchable. Embedded bookmarks open the figure index, main catalog, and reference sections. Searchable figure codes provide more specific navigation. Dense electrical assembly illustrations benefit from enlargement.

One printable 701-page PDF contains 677 pages of illustrated parts entries, a five-page figure index, 14 pages of abbreviations, and two pages of hardware conversions. The total also includes one introductory page, one figure-search guide, and one blank page.

Engine, Drivetrain and Tractor Equipment Parts

The following selected contents outline the catalog’s main systems. Other illustrated entries include diesel cold-start equipment and engine coolant heater kits.

• Engine components: Cylinder Block, Head & Related Parts and Pistons & Connecting Rods illustrations, with separate gasoline and diesel listings and engine gasket kits.

• Fuel and cooling systems: Holley and Zenith carburetor breakdowns, diesel rotor injection pumps, injectors, filters, radiators, and water-pump components.

• Transmissions and PTO: Exploded views for 6-speed, dual-range 8-speed, and manual reversing transmissions, plus Power Take-Off Assembly, clutch, and reduction gearbox parts.

• Wheels, brakes and steering: Front Wheel Assembly and rear-wheel configurations, brake linkages, pedals, master cylinders, hydraulic trailer brakes, and manual or power steering.

• Hydraulics: Hydraulic Lift Cover & Related Parts, lift cylinders, steering cylinders, engine-mounted piston and gear pumps, and single- or double-spool remote valves.

• Electrical components: Harness layouts and parts lists for starting motors, alternators, lighting, rear wiring, and the Cab Electrical System.

• Cab and safety equipment: Cab assemblies, glazing, doors, heaters, air-conditioning components, ROPS frames, seat belts, and transmission shift-pattern decals.

This catalog suits mechanics and owners who can match illustrated assemblies to their tractor’s configuration and need part numbers for repair planning or replacement-parts orders.

Matching Parts to the Installed Assembly

Cross-reference part numbers and hardware specifications directly at your workbench. Numbered illustrations connect each component to its description, quantity, and application notes, helping distinguish a complete assembly from its separately listed components.

Configuration differences: Standard and power-adjustable rear wheels have separate entries. FWD illustrations distinguish axle, differential, reduction, and transfer-box components, including collar-gear and wet-clutch arrangements. Cab and non-cab brake controls also use different parts listings.

Regional designations such as NHNA and NH-E, equipment notes, and production-date entries matter when selecting parts. Shared figures contain entries for both three- and four-cylinder tractors; a model named in one table does not establish complete catalog coverage for that model.

Engine Compatibility and Replacement Parts

The gasoline piston section flags a compatibility issue on some 1975-and-later 2600 and 3600 engines: a 4.2-inch-stroke crankshaft may be fitted instead of the standard 3.8-inch version. The listed standard pistons can then project approximately 1/4 inch above the block, creating a risk of interference and engine damage.

The crankshaft and piston entries document the relevant replacement-parts distinctions. These notes support component selection; they do not replace engine inspection or assembly procedures.

Electrical Layouts and Service Limits

Electrical illustrations show harnesses, switches, lamps, and related mounting parts in their physical assemblies. They are parts-location drawings rather than complete circuit schematics for electrical fault tracing.

Likewise, fuel-system illustrations identify pipes, pumps, filters, and fittings. Exploded transmission and steering views show component relationships, but do not provide the disassembly sequence, adjustments, or final checks required for rebuilding.

Always ensure the tractor is properly supported and hydraulic pressure is fully relieved before removing components.

Selected Rear-Wheel Hardware and Piston Sizes

For standard rear wheels, the parts table lists 5/8"-18 x 2-53/64" carriage bolts and G5 nuts. These are hardware-identification details, not tightening specifications.

Gasoline piston entries for the 2600 and 3600 distinguish standard sets from .004", .020", .030", and .040" oversizes. Each size has its own parts listing, allowing replacement-parts selection to account for the engine’s existing configuration and machining history.
