Ford F-Super Duty Chassis Cab Hydro-Boost Diagram - Hose Routing & Torque Specs

This is a Ford service-manual exploded parts diagram titled "Hydro-Boost for F-SuperDuty Chassis Cab," showing the hydraulic (Hydro-Boost) power brake booster system and its hose routing. The main illustration shows the engine assembly (6007), power steering pump assembly (3A674), steering gear assembly (3A500), booster assembly (2B559), and the pressure and return hose assemblies (3F523, 3F524, 3A713) with their routing between the pump, steering gear, and booster. Torque specifications are given for the hose tube nuts (27-41 N•m / 20-30 ft-lb) and hose clamps (1.1-2 N•m / 10-18 in-lb). A 5/8-inch return hose and retaining strap (95873-S) are also called out. Inset VIEW X details the booster and master cylinder area, with a note that hose assemblies 3F523 and 3F524 must be indexed against the booster assembly before, during, and after tightening the tube nuts. Two VIEW Y insets show pump-end hose connections specific to the 7.5L gasoline engine and the 7.3L diesel engine. The figure reference is H6259-C. A reader can learn the part numbers, hose routing, and fastener torque values for installing or servicing the Hydro-Boost system on F-Super Duty chassis cab trucks.
