Beyond the top-level assembly groups, the catalogue drills into sub-assemblies for every major system. The hydraulic section alone spans hundreds of pages covering pumps, motors, valves, cylinders, accumulators, filters, hoses, fittings, and the complete hose list with identification numbers. Electrical content includes switch cabinets, CAN modules, sensors, encoders, relays, fuses, cable looms, plugs, sockets, terminal boxes, and wiring for the tower, boom, superstructure, and undercarriage. The diesel engine section covers the D9512 A7-04 750 kW unit with crankshaft, pistons, cylinder heads, injectors, turbochargers, fuel system, cooling system, and all associated gaskets and repair kits. The undercarriage and axle arrangement details wheel sets, rigid axles, planet rigid axles, steering knuckles, brakes, tyres, and hydraulic drive components. The catalogue also includes dedicated sections for the LMT slipring unit, radio remote control, video monitoring, fire detection and extinguishing, air conditioning, lighting, labelling, and service products such as oils, greases, and analysis kits.

Each illustrated page presents an exploded view with item numbers that map directly to the parts table on the same or facing page. The parts tables provide position numbers, Liebherr article numbers, quantities, descriptions in both Spanish and English, and page references for sub-components. This structure makes the Liebherr LHM 420 parts catalogue 141959 an indispensable tool for identifying and ordering the correct spare parts for any repair or overhaul.
