TESTING AND TROUBLESHOOTING
The Komatsu PC170LC-11 manual contains troubleshooting information to help identify mechanical, hydraulic, electrical and electronic faults. Diagnostic procedures guide technicians through a logical sequence of inspections and tests before components are dismantled or replaced.
Testing and adjustment sections provide inspection methods, standard measurements, operating values and adjustment procedures. These allow actual machine performance to be compared with the specified service standards and help locate faults accurately.
This information can assist when investigating difficult starting, loss of engine power, overheating, slow hydraulic operation, reduced digging performance, abnormal work-equipment movement, travel problems, swing faults, warning indications and electrical malfunctions.
HYDRAULIC SYSTEM INFORMATION
The hydraulic sections of the Komatsu PC170LC-11 manual explain the operation of the pumps, control valves, cylinders, motors and associated hydraulic circuits.
Procedures cover hydraulic inspection, pressure testing, system adjustment, component removal, dismantling, repair and reassembly. Understanding the hydraulic circuits helps technicians diagnose slow operation, reduced hydraulic power, leakage and incorrect boom, arm or bucket movement.
Following the correct testing procedures can prevent serviceable components from being replaced unnecessarily and help ensure adjustments are completed to the specified values.
ENGINE AND ELECTRICAL SYSTEMS
Engine information covers the inspection, testing and servicing procedures required to maintain reliable machine operation. The Komatsu PC170LC-11 manual also contains technical guidance for the fuel, cooling, intake, exhaust and lubrication systems.
Electrical information assists with diagnosing starting, charging, monitoring and machine-control problems. Wiring information, component locations and testing procedures help identify faulty circuits, poor connections, switches, sensors and electronic components.
ELECTRONIC CONTROL AND MONITORING
Electronic control information assists with investigating machine warnings, diagnostic indications and performance problems. System descriptions help technicians understand how electronic components communicate with the mechanical and hydraulic equipment.
Correct diagnostic procedures allow wiring, sensors, switches, controllers and associated components to be tested before replacement parts are ordered.
TRAVEL, SWING AND UNDERCARRIAGE
Technical information covers the travel motors, final drives, swing machinery, tracks and associated undercarriage components. Inspection and repair procedures help identify wear, damage and incorrect adjustment before more serious problems develop.
The long-carriage undercarriage requires accurate inspection of the tracks, rollers, idlers, sprockets, final drives and related components. Correct maintenance helps reduce unnecessary wear and maintain reliable travel performance.
DISASSEMBLY AND ASSEMBLY
The Komatsu PC170LC-11 manual provides step-by-step procedures explaining the correct sequence for removing, dismantling, inspecting, assembling and installing major components.
Instructions include important measurements, inspection points, service limits and adjustment requirements where applicable. Technical illustrations and exploded views help identify individual parts and show their correct positions during reassembly.
This information is particularly useful when carrying out major engine, hydraulic, travel, swing, work-equipment or undercarriage repairs.
