Component and System Overview

This manual provides critical technical data for the structural adjustment and general maintenance of the excavator range. Organized by major system groups, the publication documents the engine, hydraulic circuitry, electrical components, swing gear, and undercarriage systems. Each chapter segments the machine into logical service zones. Look for specialized sections breaking down the splitting box, the oscillating axle stabilizer, and the HVAC cab environment. Working on heavy machinery carries inherent risks. Technicians must carefully review all factory-specified pressure relief procedures and load charts before engaging the hydraulic or lifting systems to prevent severe injury or equipment damage.

Specification Highlights

Technical data includes extensive torque tables for Ermeto couplings and standard metric hardware. ISO tolerance charts for shafts and bores are mapped out clearly. System capacity for the engine oil is documented at 28 liters. Maximum hydraulic pump output is specified at 103 kW. The lubricants chart lists permissible engine oil operating temperatures between -10°C and +20°C (14°F to 68°F). This official Liebherr workshop documentation serves as the primary technical reference, providing the exact assembly and system specifications required for professional workshop environments.
