The Claas Lexion 480 Repair Manual 188678.1 is a comprehensive workshop document spanning over one thousand pages, dedicated entirely to the CLAAS Lexion 480 combine harvester. This January 2004 edition covers every major system on the machine — from the feed rake conveyor and threshing concave through to the axial rotors, cleaning fan, grain tank unloading, hydraulic circuits, and the Mercedes OM 441 LA engine. Each section is structured with step-by-step removal, disassembly, assembly, and installation procedures, supported by measurements, tightening torques, and special tool references where applicable. The manual also includes drive diagrams, a sectional view of the machine, a lubricants chart, hydraulic pressure values, and basic concave settings — making it a complete reference for anyone maintaining or repairing the Lexion 480.

What This Manual Enables You to Do

With this Claas Lexion 480 repair manual on hand, you can confidently tackle repairs and adjustments across the entire combine — not just routine maintenance. Whether you are removing the threshing drum, disassembling the axial rotor gearbox, replacing the cutterbar drive belt, servicing the hydrostatic ground drive, or rebuilding the final drive gearbox, the procedures are laid out with the precision you would expect from a factory workshop document. The manual covers both left-hand and right-hand drive belts, the variable-speed drive systems, the grain tank unloading angle drives, and the complete hydraulic valve combinations, so you have the information needed for both mechanical and hydraulic work.

Correct procedures and accurate specifications matter enormously on a machine like the Lexion 480, where clearances, torques, and timing directly affect threshing performance and reliability. This manual provides the basic concave settings, the potentiometer linkage adjustments, the axial rotor wear edge clearance, the hydraulic pressure values, and the tightening torques for critical assemblies — from the M 65 face-end slotted nut on the drum bearing to the 520 Nm castellated nut on the engine output pulley. Having these figures at hand helps prevent costly damage and ensures the machine is put back together to specification.
