TESTING AND TROUBLESHOOTING
The troubleshooting information helps technicians identify the causes of mechanical, hydraulic and electrical problems. Diagnostic procedures provide a logical sequence of checks before components are removed or replaced.
Testing and adjustment sections contain inspection methods, standard measurements and operating values. These allow actual machine performance to be compared with the correct service specifications and help locate faults accurately.
This information is valuable when investigating difficult starting, loss of engine power, slow hydraulic operation, weak digging performance, unusual attachment movement, travel problems, swing faults or electrical malfunctions.
HYDRAULIC SYSTEM INFORMATION
The hydraulic sections explain the operation of the pumps, valves, cylinders, motors and associated circuits. Procedures cover hydraulic inspection, pressure testing, adjustment, component removal, dismantling and reassembly.
Understanding the hydraulic circuits can help identify the causes of slow operation, reduced power, hydraulic leakage and incorrect work-equipment movement. Correct testing procedures can prevent serviceable components from being replaced unnecessarily.
ENGINE AND ELECTRICAL SYSTEMS
Engine information covers the inspection and servicing procedures needed to maintain reliable operation. The manual also contains technical information for the fuel, cooling and lubrication systems.
Electrical information assists with diagnosing starting, charging, lighting, monitoring and control problems. Component locations, wiring information and test procedures help identify faulty connections, switches, sensors and other electrical components.
TRAVEL, SWING AND UNDERCARRIAGE
The Komatsu PC35R-8 and PC45R-8 use compact travel, swing and undercarriage systems designed for excavator operation in restricted working areas. The manual provides repair information for the travel motors, final drives, swing machinery, tracks and associated undercarriage components.
Inspection information helps identify excessive wear, incorrect adjustment and damaged components before more serious problems develop.
DISASSEMBLY AND ASSEMBLY
Step-by-step procedures explain the correct sequence for removing, dismantling, inspecting, assembling and installing 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 is particularly useful when completing hydraulic, travel, swing or undercarriage repairs.
