Built for Diagnosis, Testing and Repair

This E485 workshop manual goes well beyond routine operating information. Its introduction states that it is written for an experienced technician and provides the technical information needed to maintain and repair the machine. The material is arranged so that the technician can first understand how the machine and its systems operate, then check performance against standards, trace faults, and finally carry out component removal, installation, disassembly, inspection, repair and assembly.

The operational-principle material explains the mechatro control system, controller functions, hydraulic circuits and electrical circuits in depth. It follows individual circuits for bucket, boom, arm, swing and travel operations, including combined operations, travel-straight control, swing priority, pressure releasing, crusher and breaker circuits, and pump control. The electrical coverage includes power, accessory, starting, charging, preheating, engine-stop and emergency operating circuits, with circuit diagrams and component layouts.

For fault finding, the manual includes mechatro self-diagnosis, service diagnosis and trouble-history functions as well as dedicated troubleshooting groups for the mechatro control, hydraulic system, electrical system and engine. This makes the New Holland Kobelco E485 Excavator Workshop Manual 604.13.472 – March 2005 PDF useful when a repair needs more than a parts-location drawing: the technician can follow the system logic, check test conditions and measurements, and then move into the relevant repair procedure.

Machine and Engine Technical Data

The specification section identifies important E485 machine data and the major hydraulic and engine components used in the manual. For the E485LCH monoblock version, the manual shows 2 900 mm, 3 450 mm and 4 040 mm arm configurations and provides transport dimensions, working weights, track-shoe widths and digging data. The E485BEH section has its own transport and digging information. Excavator performance data includes a 70% gradeability figure and travel speeds of 3.5 km/h in first speed and 5.6 km/h in second speed.

The listed ISUZU AA-6SD1XQY engine is a four-cycle, water-cooled, vertical in-line direct-injection six-cylinder engine. The manual gives a 120 mm bore, 145 mm stroke, 9 839 cm3 total displacement, 16.8:1 compression ratio, net flywheel power of 235.4 ± 3.77 kW and torque of 1275 Nm at 1600 min-1. It also identifies the injection system, battery arrangement, starter and alternator data. These specification pages sit alongside extensive engine repair material covering disassembly, inspection and repair, assembly, lubrication, cooling, fuel, turbocharger, engine electrical, troubleshooting, special tools, repair standards and the electronic control system.

Hydraulic specifications identify the main pump as K5V200DPH1BDR-9TAW-V and the pilot gear pump as ZX15LSLZ2-07D, with main-pump maximum flow listed as 370 × 2 L/min. The control valve is identified as UY36-110. Separate data is provided for pilot valves, right- and left-hand swing motors, the travel device and the boom, arm and bucket cylinders. These values support both performance checks and component-level service work without forcing the technician to rely only on general descriptions.

Taken together, these chapters provide a complete technical path through the machine. Component layouts and system descriptions establish how the E485 is built and how its controls interact; performance-test sections show how engine speed, hydraulic pressure, travel, swing, attachment operation and swing-bearing performance are checked; troubleshooting sections organize fault diagnosis; and the repair chapters provide the mechanical procedures needed once the problem area has been identified.

Performance Tests and Diagnostic Functions

The performance-test section includes maintenance standards and test preparation, followed by a performance inspection standard table and procedures for measuring engine speed, hydraulic pressure, travel performance, swing performance, attachment operating performance and swing-bearing performance. It also includes mechatro controller adjustment information. The manual specifies test conditions and measurement methods so results can be compared with the standards provided in the document.

The mechatro controller section adds another layer of diagnostic support. It explains self-diagnosis of control inputs and outputs, service-diagnosis displays and stored trouble history. Fault items include pressure sensors, pump sensors, proportional valves, solenoid valves, engine speed sensing and accelerator-related signals. The hydraulic chapters then explain the circuits those components control, helping connect a displayed or measured fault to the underlying hydraulic operation.

Repair Coverage Across the Excavator

Repair instructions extend across the upperstructure, undercarriage, front attachment and engine. Upperstructure work includes the cab, air conditioner, counterweight, main frame, pump device, control valve, swing device, pilot valve and solenoid valve unit. Undercarriage coverage includes the swing bearing, travel device, swivel joint, track adjuster, front idler, upper and lower rollers and tracks. Front-attachment coverage addresses the attachment and cylinders.

The engine section is especially extensive. In addition to disassembly and assembly sequences, it includes inspection and repair procedures, repair standards, measurements, tightening information and special-tool references. Troubleshooting topics include starting problems, unstable idling, lack of power, excessive fuel or oil consumption, overheating, exhaust smoke, low oil pressure and abnormal engine sounds. The electronic-control material covers system configuration, the RED IV governor, component operation, control functions, fail-safe functions, ECU connections, troubleshooting and self-diagnostics.
