Part of the Hyundai Repair Manuals.
All 558 pages of this Hyundai HL760-9, HL760XTD-9 Service Manual PDF point at one machine: your wheel loader, from torque converter to bucket pin. Inside: full electrical circuit diagrams with component locations and connector charts, hydraulic schematics for the steering and brake circuits, and fault code tables covering machine, engine, and transmission. You also get complete powershift transmission disassembly and assembly steps, clutch pack procedures, and troubleshooting charts for the brake, steering, and work equipment systems. Torque the front axle mounting bolts to 135 kgf·m (976 lbf·ft), then set the main control valve overload relief at 340 kgf/cm2 (4840 psi). A loader stuck in second gear doesn't care what the forum thinks. Bookmarked and keyword-searchable; pull it up on your phone at the machine, find the spec, and get wrenching.
