Ford 420 3 Cylinder Tractor Loader Backhoe Parts List 1975-1978

This 601-page OEM parts catalog breaks down the 1975–1978 Ford 420 3-cylinder tractor, loader, and backhoe variants. It covers both gasoline and diesel-powered configurations across multiple transmission setups. Instead of generic overviews, expect a factory-authorized look at the entire build designed for heavy shop work.

• Contains 98 exploded-view diagrams and assembly illustrations for precise hardware positioning.
• Maps out engine, chassis, hydraulic, and electrical system sub-assemblies.
• Provides accurate component part numbers to streamline workshop ordering and prevent mismatched hardware.

Assembly and System Coverage

Need to rebuild the rear end or trace a hydraulic leak? The catalog maps out the front axle, steering components, rear axle assemblies, and differential lock linkage. For the powerplant, you get a complete breakdown of the 3-cylinder engine block. This includes the cylinder head, pistons, crankshaft, and fuel system parts for both gas and diesel models.

Transmission coverage is highly detailed. It spans the torque converter, 8-speed gearboxes, 6x4 manual reversing systems, and PTO assemblies. Hydraulic lift systems get their own dedicated breakdowns so you can easily trace control valves, lift cover assemblies, and the cylinder linkages critical for implement management. Auxiliary equipment documentation covers stabilizer kits, quick-attach hitches, and rear wheel weight setups for various tire configurations.

Component Identification Data

Proper hardware identification prevents downtime. The catalog lists assembly-specific hardware, calling out precise sizes like 1/2"-20 wheel bolts and exact hex-flange nuts. Cylinder head and engine block repair kits show specific stud and gasket markers so you know exactly what is included in a teardown.

You will find hydraulic system specifications noting pump pressures from 650 PSI up to 1600 PSI, depending on your specific installation. Always verify these system pressures and hardware specifications against factory parameters before servicing equipment to maintain safe operating conditions in your workshop. Electrical sections lay out pinout references for lighting and starting circuits, while steering gear diagrams highlight shim thicknesses and gear ratios. This documentation gives technicians the exact visual reference needed for ordering components and reassembling complex systems.
