1975–1981 Ford 7600 Tractor Parts Catalog with Shared 5600, 6600, 5700, 6700 & 7700 Listings

This Ford illustrated parts catalog is indexed for the 1975–1981 7600 agricultural tractor. Shared assembly listings also cover 5600, 6600, 5700, 6700, and 7700 applications, including C-series and Swiss variants where identified. Coverage follows the individual figure and part entry; shared listings do not represent complete separate catalogs for every model named.

• Engine components: Cylinder block and head, crankshaft, pistons, connecting rods, valve gear, water pumps, gasket sets, and engine overhaul kit contents.

• Turbochargers and fuel: Separate Schwitzer and AiResearch turbocharger breakdowns, inline injection pump components, diesel injectors, fuel filters, and cold start heaters.

• Transmission and driveline: Dual-range gear assemblies, Dual Power units, PTO assemblies, FWD transfer boxes, differential carriers, and hub planetary drives.

• Hydraulics and hitches: Lift covers and cylinders, load monitor components, center-housing gear pumps, remote control valves, and automatic pick-up hitch kits.

• Wheels, steering, and brakes: Front hubs, rear wheel configurations, manual and power steering gear, wheel brakes, handbrakes, and hydraulic trailer brake components.

• Electrical and cab equipment: Harness and lamp layouts, starter and alternator parts, instrument clusters, safety frames, seating, and cab heating equipment.

This catalog is suited to mechanics and experienced owners who can match exploded-view callouts to installed assemblies and interpret model-specific application notes.

Assembly and Component Breakdown

The Front Wheel Assembly drawing identifies hub bearings, grease retainers, and mounting hardware. Rear wheel coverage distinguishes standard, power-adjustable, and dual power-adjustable arrangements, with separate listings for front-end weights, ballast slabs, and bumper kits.

ROPS safety frames and Super Comfort seats have their own component breakdowns. Swinging drawbars and automatic pick-up hitches are separated by configuration, helping you identify the brackets, pins, and attaching parts that belong together.

Engine and Drivetrain Parts Matching

The Cylinder Block, Head & Related Parts section records additional hardware required with certain replacement blocks and heads. Piston and connecting-rod listings distinguish replacement combinations involving old and new crankshafts; one combination refers to a separate catalog.

Schwitzer and AiResearch turbochargers have separate exploded views, with a note requiring the replacement to match the installed design. Inline injection pump drawings identify internal components and associated hardware, without providing pump calibration procedures.

The Transmission Dual Power Assembly listings include clutch-plate replacement sets. Other transmission entries warn that D0NN- and C5NN-prefix bearings and cups cannot be mixed; incompatible combinations can damage the bearing assembly. These application notes help you order matched components before beginning a repair.

Hydraulic and Electrical Assembly Identification

Hydraulic Lift Shaft illustrations distinguish assemblies with and without a load monitor. The Hydraulic Lift Load Monitor drawing identifies its internal parts, while remote valve listings separate single- and double-spool equipment and the associated seal kits.

Electrical System, NH-E and Cab Electrical System drawings show harnesses, connectors, switches, and attaching parts. Separate rear wiring and charging-system groups support component identification. These are illustrated parts layouts, not diagnostic circuit schematics.

Parts-Catalog Scope and Cab References

Exploded views show component relationships; workshop repair sequences, adjustment procedures, and diagnostic tests require separate service literature. The rear cab crossbar repair-kit entry uses a cab serial reference and date-code cutoff, but directs installation work to Service Bulletin #9 (1980), which is not included.

Always verify safety protocols and consult a certified technician before performing service on this equipment.

Examples of Engine Replacement Sizes

These examples show a small selection of the replacement-part dimensions listed in the catalog.

For the 7600/7700 engine, piston-ring kits include a 0.020-inch oversize option, while connecting-rod bearing kits include a 0.010-inch undersize option. These are part-size designations for replacement selection, not cylinder wear limits or bearing-clearance specifications.

PDF Search, Navigation, and Page Breakdown

Text search and drawing detail: The figure index and parts tables contain searchable text; callouts embedded in illustrations are not searchable. Bookmarks lead to the main sections. Small drawing callouts are readable with zoom, but some long headings and table entries are clipped at the right page edge.

One printable, 643-page PDF contains 619 pages of parts illustrations and lists, a five-page figure index, 14 pages of abbreviations, and two hardware-conversion pages. The total already includes one introductory banner page, one figure-search guide page, and one blank page.
