• Documents specific mechanical setups for the Select-O-Speed transmission and diesel-injection systems.
• Serves as the foundational reference for complete assembly, diagnostics, and maintenance specifications.
• Provides step-by-step repair instructions for single and double clutches, Sherman step-up transmissions, rear axles, and power take-off (PTO) assemblies.
• Details overhaul procedures for hydraulic lift cylinders, power steering pumps, brake camshafts, row crop pedestals, and LP-Gas fuel valves.

Mechanical and Power Plant Documentation

This manual provides a highly detailed technical breakdown of the power plant, giving you the step-by-step repair instructions needed for high-cost jobs typically reserved for dealerships, such as overhauling the hydraulic lift cover or rebuilding the Sherman transmission. It covers engine removal, cylinder head servicing, valve train specifics, the oil pump, and complete lubrication systems. You will find exact specifications for dismantling and inspecting main bearings, crankshaft components, and the governor or timing gear assemblies across both gasoline and diesel models. The publication also documents cooling system parameters—including a 15-quart capacity—alongside radiator care and water pump specifications necessary for maintaining these classic machines.

When servicing these classic Ford models, mechanics must be aware of specific repair pitfalls. For instance, failing to strictly adhere to the Select-O-Speed transmission band adjustment sequences will quickly cause the clutch packs to slip and prematurely fail. Additionally, neglecting to precisely time the diesel fuel injection pump often leads to severe cold-start issues and continuous misfires under heavy load. Always review the factory safety protocols before lifting heavy engine components or opening pressurized fluid systems to prevent severe workshop injuries.

Electrical and Ignition System Specifications

Mapping out the electrical architecture, this reference details both 6-volt and 12-volt wiring circuits. It breaks down charging system troubleshooting, starting motor overhauls, and ignition switch configurations. To further support your workshop evaluations, the manual features specific visual aids like the Valve Initial Adjustment Chart, the Engine Lubrication System diagram, the Manifold Vacuum Gauge Readings table, the Distributor Disassembled view, and the Engine Does Not Develop Full Power road map. The text lists critical reference values, such as the 450 rpm baseline for engine diagnostics, and outlines spark advance settings. For technicians evaluating engine timing and distributor service, the factory documentation provides precise valve clearances, listing the intake at 0.014–0.016 inches. Every diagnostic chart and adjustment table is presented exactly as Ford engineers originally structured it for dealership mechanics.
