Part of the New Holland Repair Manuals.
Tearing down and rebuilding a backhoe loader is what the 789-page New Holland LB75 service manual PDF (OEM 86618975) handles, from engine overhaul and injection pump timing through the Power Shuttle transmission, four-wheel drive front axle and cab air conditioning. Wiring diagrams trace the starting, charging and transmission electrical circuits, while hydraulic schematics map flow from both pumps through the control valves to the loader, backhoe and hammer circuit. Troubleshooting charts and pressure and flow tests sit right beside them, so your gauge readings have a factory number to answer to. Expect 20.6 GPM from each pump at 2350 rpm and 2030 psi (140 bar) at the steering relief, and torque the oil drain plug to 25-40 ft. lbs. (34-54 N·m) on reassembly. Alone with a dead boom, there's nobody to ask. Bookmarks drop you straight into any of the nine sections, Engine through Accessories, and the text layer finds a spec the moment you type it.
