Description

Fiat Kobelco EX125W Excavator Workshop Service Repair Manual

The Fiat Kobelco EX125W Excavator Workshop Service Repair Manual 604.13.240 – July 2002 PDF Download is a detailed technical repair reference for the EX125W wheeled excavator. Prepared for skilled technicians, it covers the machine from general specifications and system operating principles through component removal, disassembly, inspection, assembly, troubleshooting and operational performance testing. The manual also contains a substantial engine section for the PERKINS 1004.40T used in the EX125W.

This is a broad workshop-level manual rather than a basic operator guide. Its 11 main sections cover the upperstructure, wheeled undercarriage, front equipment, hydraulic and electrical systems, diagnostics, test procedures and engine repair. Technical drawings, hydraulic layouts, component illustrations, dimensional data, adjustment information and repair sequences are distributed throughout the manual to support practical workshop work.

EX125W Technical and Repair Information

The manual starts with machine identification, construction features and specification data before moving into the repair sections. The EX125W specification material includes dimensions, digging performance, lifting capacity and filling information. The engine is identified as a PERKINS 1004.40T, with four cylinders, 3990 cm3 displacement and 100×127 mm bore and stroke. The specification section gives setting power figures of 74.5 kW to ISO/TR14396 and 67 kW to 80/1269 CEE, together with rated speed, hydraulic performance and machine operating data.

The hydraulic information is especially extensive. The EX125W uses a Load Sensing closed-centre equipment system and a CSS Cross Sensing System swing circuit. General specification data identifies two variable-displacement main pumps, with equipment/travel output up to 150 l/min at 2000 rev/min and a maximum operating pressure of 350 bar, while the upperstructure swing circuit is specified at up to 53 l/min and 310 bar. Later chapters go considerably further, explaining individual pumps, regulators, control valves, pilot circuits, accumulators, steering and brake hydraulics, travel circuits and system diagrams.

Workshop procedures are supported by tightening values, inspection information, service data and illustrated component sequences. Examples range from cab, counterweight and superstructure removal to hydraulic pump overhaul, control-valve servicing and hose/connection practices. The manual also includes filling and lubricant information for the engine cooling system, fuel tank, engine, gearbox, swing reduction unit, axles and hydraulic system.

Together these chapters provide a system-by-system view of the EX125W and show how assemblies work before moving into the procedures needed to inspect, dismantle, repair and reinstall them. The combination of operating principles and disassembly/assembly information is particularly useful when a fault has to be traced beyond a single component rather than simply replaced by guesswork.

Hydraulic, Electrical and Diagnostic Coverage

The Fiat Kobelco EX125W workshop manual contains both hydraulic theory and practical test information. Hydraulic chapters trace the main, pilot, brake and steering circuits and describe components such as variable-displacement pumps, the main control valve, swing system, center joint and travel hydraulics. Detailed diagrams show piping relationships and circuit operation, while component repair chapters provide disassembly, inspection and assembly sequences.

Electrical coverage includes component location, instruments and controls, system arrangement, fuse and relay connections, controllers, monitor connections and individual electrical components. These sections lead into dedicated troubleshooting material for hydraulic and electrical faults. The troubleshooting section separates problems by machine function, including front attachment, swing, travel, brakes, steering, axles and transmission, helping technicians narrow a symptom to the relevant circuit or component.

The operational performance test section adds measured testing after diagnosis or repair. It includes performance standards, preparation requirements, excavator tests and component tests. Hydraulic testing material covers pump performance and pressure checks, including procedures that use pressure gauges and specified operating conditions. This makes the manual useful not only for taking components apart but also for checking whether the repaired machine or system is performing to the stated values.

Machine Specifications and Workshop Reference Data

The specification chapters give a useful baseline before service work begins. Along with the PERKINS 1004.40T engine data, the manual documents the hydraulic cylinders, drive line, controls, axles, upperstructure swing, brakes, steering, electrical system, tyres, operating weights, dimensions, digging ranges and lifting information. Triple-articulation operating weights are listed for rear-blade, rear-stabilizer and combined rear-stabilizer/front-blade configurations.

Fluid and lubricant charts provide quantities and lubricant specifications. The chart includes a 211 litre fuel tank, 21.5 litre engine cooling system, 8.5 litre engine-oil quantity and hydraulic-system filling information, along with gearbox, swing reduction and axle quantities. Workshop sections add component-specific values such as hydraulic filter data, pressure settings, tightening torques and adjustment information where required by the procedure.
