Hyundai Robex 130LC-3 & 130LCM-3 1995–1998 Factory Service Manual OEM

Get the specs right. This 476-page official factory PDF manual provides professional mechanics and equipment owners with the exact technical reference data needed to service and repair the 1995–1998 Hyundai Robex 130LC-3 and 130LCM-3 crawler excavators. It cuts down diagnostic time by mapping out every electrical and hydraulic circuit.

Working on heavy hydraulic systems carries inherent risks. Always consult the comprehensive safety protocols detailed in the opening chapters before testing hydraulic pressures or servicing the travel motor.

Manual Scope & Workshop Benefits

This reference guide focuses entirely on structural makeup and functional parameters. Rather than generic tutorials, it delivers hard diagnostic data, component locations, and disassembly/assembly sequences for major systems.

• Hydraulic System Schematics: Traces circuit operations across single and combined work modes.
• Mechatronics & Electrical: Full coverage of the CAPO (Computer Aided Power Optimization) system, engine control integration, and monitoring data.
• Troubleshooting Charts: Links specific mechanical or electrical symptoms directly to root component failures.
• Covered Components & Assemblies: Delivers precise technical data for the Cummins 4BTA3.9 engine, main pump device, swing device, travel device, turning joint, RCV lever and pedal, and the boom, arm, and bucket cylinders.
• In-House Overhauls & Rebuilds: Features step-by-step disassembly and assembly sequences for the main control valve, swing motor reduction gears, travel motor parking brakes, gear pumps, track rollers, front idlers, and recoil springs.

By following these factory-approved procedures, your shop can confidently tackle heavy component overhauls on the floor—saving thousands by not outsourcing to an expensive dealership. To completely eliminate parts-swapping and accurately isolate electrical faults, this guide includes highly detailed wiring diagrams for the entire machine. Navigating these repairs is further streamlined by comprehensive visual aids, including hydraulic circuit diagrams, internal cross-section drawings, component location views, flow control characteristic charts, and operational performance test charts. This allows technicians to directly translate mechanical symptoms into measurable electrical values, such as verifying EPPR valve resistance with a multimeter instead of replacing expensive parts on a hunch.

Critical Diagnostic Specifications

Having the correct pressure settings makes the difference between a quick calibration and hours of wasted time. Key parameters documented in this manual include:

• Engine oil capacity: 11 liters
• Main control valve relief pressure: 320 kgf/cm² (4,550 psi) with power boost up to 350 kgf/cm² (4,980 psi)
• Travel motor high-pressure setting: 320 kgf/cm² (4,550 psi)
• Swing motor relief pressure: 220–240 kgf/cm² (varies by serial number range)
• Swing motor brake release pressure: 17–40 kgf/cm² (model version dependent)
