Chapters Covered

The manual is organised into five principal parts, each addressing a critical area of excavator service and repair.

• Safety Precautions
• Operational Principle
• Operational Performance Test
• Troubleshooting
• Repair Instructions

Safety Precautions

This opening section establishes the safety framework for all work on the E175B and E195B. It covers general safety rules for disassembly and assembly, including the correct procedures for releasing hydraulic pressure from the system before opening any circuit. Safety plates and their meanings are illustrated, and the manual uses standardised signal words (DANGER, WARNING, CAUTION, IMPORTANT, NOTE) throughout. Specific precautions address hydraulic fluid hazards, battery safety, high-pressure line risks, and the correct use of lifting equipment. This section should be read before any repair work begins.

Operational Principle

The operational principle section explains how the major systems function. It begins with the Mechatro Control System, covering the electronic control of pump flow, positive control, P-Q control, and the various conflux and priority control strategies (boom up conflux, arm in recirculation, swing priority, travel straight, etc.). The hydraulic circuits chapter details the main hydraulic circuit components and their connections, including neutral circuit operation, travel circuit, bucket circuit, boom circuit, swing circuit, arm circuit, and combined circuits. The electrical system chapter provides overall system diagrams, wiring harness layouts, and component descriptions. Together these chapters give the technician a full understanding of machine operation before troubleshooting or repair.

Operational Performance Test

This section provides the standard performance data and test procedures needed to verify machine condition. It includes performance inspection standard tables for both the E175B and E195B, covering engine speed, hydraulic pressures, operating speeds, travel speeds, swing speeds, and brake performance. Detailed test procedures explain how to measure engine speed, hydraulic pressure, travel performance, swing performance, and attachment operating times. The maintenance standard tables list standard values, reference values for remedy, and service limits, allowing the technician to judge whether components are within specification or require attention.

Troubleshooting

The troubleshooting section is divided into three groups. The first covers troubleshooting by error code, listing the self-diagnosis codes that the Mechatro controller can generate and the corrective actions for each. The second group addresses troubleshooting by symptom, covering hydraulic system problems (slow operation, insufficient power, drift, noise) and electrical system faults. The third group explains the trouble diagnosis mode, which allows the controller to automatically test the unload system, pump system, travel straight system, and pilot system to identify failed components. This section is particularly valuable because it combines the electronic self-diagnosis capability with systematic hydraulic and electrical fault-finding.

Repair Instructions

The repair instructions form the largest part of the manual. They begin with general information on precautions for disassembly and assembly, followed by a comprehensive tightening torque chart that covers metric bolt sizes from M6 through M36 and specific torque values for pipe joints. The upperstructure section covers removal and installation of the cab, counterweight, main frame, hydraulic pump, control valve, swing device, and pilot valves, with detailed disassembly and assembly procedures for each component. The undercarriage section addresses the swing bearing, travel device, swivel joint, track adjuster, front idler, upper and lower rollers, and tracks. The front attachment section covers removal and installation of the boom, arm, bucket, and all cylinders, plus cylinder disassembly and assembly procedures with seal replacement instructions.

Component Operation

A separate component operation section provides in-depth explanation of the hydraulic pump assembly (including the regulator, PTO gear case, and control curves), pilot valve construction and operation, control valve construction and operation (including relief valves, spool functions, lock valves, and by-pass cut valves), swing device (motor, brake, and reduction unit), travel device (hydraulic motor, planetary gearbox, and brake), swivel joint, cylinders (boom, arm, bucket, and positioning), and the air conditioner system (including refrigerant charging procedures and troubleshooting).

What This Manual Enables You to Do

With this New Holland Kobelco E175B E195B workshop manual, you can perform the full range of service and repair tasks on these excavators. The manual covers:

• Engine removal, installation, and service procedures for the CNH 445TA/MLF diesel engine
• Hydraulic pump disassembly, inspection, and reassembly with maintenance standards
• Control valve overhaul including relief valve adjustment and spool inspection
• Swing motor and swing reduction unit disassembly and repair
• Travel motor and planetary gearbox disassembly, inspection, and assembly
• Cylinder resealing and rebuilding for boom, arm, bucket, and positioning cylinders
• Track adjuster service and front idler rebuilding
• Swivel joint disassembly and seal replacement
• Mechatro control system diagnostics and adjustment
• Hydraulic and electrical troubleshooting using error codes and diagnostic modes
• Performance testing to verify machine condition against standard values
• Air conditioner system service and refrigerant charging

Why This Manual Matters

Working on a modern hydraulic excavator without the correct specifications and procedures is risky. Incorrect torque values can cause bolt failure or component damage. Improper assembly of hydraulic components can lead to contamination, leaks, or catastrophic failure. Misdiagnosis of electronic control faults can result in unnecessary parts replacement. This manual provides the exact torque values, clearances, service limits, and diagnostic procedures that New Holland Kobelco specifies for the E175B and E195B. It includes the maintenance standards that tell you when a component is still serviceable and when it must be replaced. The troubleshooting sections help you identify the root cause of a problem before you start removing parts.
