Get the exact part numbers you need for your 4-cylinder Ford agricultural tractor built between 1975 and 1981. This 661-page PDF parts catalog provides the authoritative visual index for standard variants alongside FWD, Load Monitor, and specific cabin configurations. By referencing these comprehensive factory illustrations paired with original OEM component numbers (PN 83909956) before tearing down a machine, mechanics can verify component routing and assembly sequences directly at the workbench, significantly minimizing equipment downtime.

Catalog Highlights & Specs

• Detailed breakdowns of front axle and steering assemblies, including manual and power-assisted gear setups.
• Complete schematics for front wheel and wafer weight configurations.
• Exhaustive lists for hardware: find exact bolts, seals, bushings, and shim specifications (including the .014–.028 inch ranges for front axle supports).
• Complete engine component breakdowns covering the cylinder block head, crankshafts, camshafts, oil pumps, flywheels, rotor injection pumps, and inline injection pumps.
• Extensive visual indexes for the 7 and 8-speed transmissions, power take-off (PTO), starting motors, alternators, instrument clusters, A/C compressors, tractor cabs, and flat top fenders.

Hydraulic & Braking Systems Overview The documentation thoroughly illustrates the lift cover, control valves, and remote cylinder kits. You will also find full assembly views for the transmission handbrakes and hydraulic trailer brake systems. When working on pressurized systems, always verify your specific relief valve settings against current machine parameters to ensure safe operation before installing new components. These settings are clearly documented here at 650, 850, 1100, and 1600 PSI.

Drivetrain, Wiring & Teardown Views The manual maps out extensive wheel and axle setups. It covers everything from standard rims to dual-power adjustable rear wheels and various tire-mounting hardware. While this catalog focuses on parts identification rather than written step-by-step repair or troubleshooting instructions, the highly detailed exploded-view drawings act as a strict visual step-by-step guide for assembly and disassembly. This allows you to confidently manage complex shop tasks—such as rebuilding the 7 and 8-speed transmission or overhauling the fuel injection pump—without paying for an expensive dealership visit.

Beyond mechanical parts, this manual includes comprehensive wiring diagrams for the cab and main harnesses. To further speed up your bench work, you gain access to specific electrical system charts, fuel system schematics, A/C compressor views, PTO clutch views, and implement lamp diagrams.
