00 Index and Foreword

The opening section provides the complete shop manual composition, a table of contents for every module, and the foreword covering safety, general information, and how to read the manual. It includes detailed safety rules for operating and servicing the truck, working near batteries, tire handling, welding precautions, jack point locations, handling of electrical and hydraulic components, standard torque tables, and conversion tables. This is the section to read first before any service work begins.

01 Specification

Contains the specification drawing with overall dimensions, the complete truck specification table, the weight table for major components, and the fuel, coolant, and lubricant recommendations. Engine, AC drive system, steering, suspension, tire, brake, and hydraulic system specifications are all listed with their operating values and capacities.

10 Structure, Function and Maintenance Standard

This is the largest technical section and covers the structure, function, and maintenance standards for every major system on the truck:

• Cab air conditioning — principles of refrigeration, system components, and electrical circuit.
• Steering circuit — operation, components, flow amplifier, steering/brake pump, and steering cylinder wear data.
• Hoist circuit — operation, components, hoist pilot valve, and hoist cylinder wear data.
• Brake circuits — service brake, secondary braking and auto apply, rear wheel brake lock, parking brake, brake warning circuits, and brake assembly wear data.
• Suspensions — general information and front/rear suspension wear data.
• Electrical system, 24V — battery supply, auxiliary control cabinet components, relay boards, body-up switch, and hoist limit switch.
• Interface module (IM) — general information, service, sensors, and IM inputs/outputs.
• Electrical system, AC drive — SR rectifier module, ST module, SD phase modules, inverter cabinet layout and water flow, field regulator, gate unit power supply, control power filter, fuses, diode modules, support capacitors, 3-phase capacitor bank, air-cooled inductors, 3-phase transformer, diagnostics box, current and voltage transducers, inclinometer, DC link capacitors, bus bars, contactors, temperature probes, coolant sensors, circuit breakers, blower fans, coolant pump, radiators, ground monitoring resistors, crowbar protection, discharge reactor, main blower motor, grid box, main alternator, IGBT inverter/chopper modules, rectifier module, ground tie resistors, speed sensors, and traction motor.
• SiBAS® IGBT rack components — detailed coverage of the SiBAS®32 Traction Control Unit (TCU), card removal and installation, device names, part number structure, interchangeability, card interactions, and every card type including CPU, DSP, I/O, TRACO, input voltage/frequency, analog I/O, pulse amplifier, temperature sensor, UWS, digital input, power start-up, binary output, and power supply cards.
• Reserve engine oil system — general information, operation, and remote tank fill system.
• Wheel motor transmission — general information and transmission wear data.

20 Standard Value Table

Provides the standard value table for the truck, including travel speed, engine speed, operating forces, dimensions, suspension cylinder installed length and nitrogen pressure, accumulator pressures, oil pressures, and relief valve settings. These are the reference values used during testing and adjusting.

30 Testing and Adjusting

Contains the special tool list and detailed procedures for testing and adjusting every major system. Covered topics include cab air conditioning service, steering system checkout, brake cooling and hoist hydraulic system checkout, brake circuit checkout, accumulator charging and leak testing, suspension oiling and charging, payload meter initial setting, Komtrax Plus setup, interface module checkout, and the complete SiBAS® user manual parts 1 and 2 including the customer monitor and Traco menus.

40 Troubleshooting

The troubleshooting section is organized by fault code and covers the cab air conditioning system, fuse and circuit breaker locations, fault codes A001 through A365 for the truck systems, and the complete drive system fault code tables including SiBAS® event codes, UWSA/UWSB/UWSST codes, and all associated diagnostic information. Each fault code entry includes fault conditions, operator alerting, system response, and repair information.

50 Disassembly and Assembly

Provides the special tools and step-by-step procedures for removing, installing, disassembling, and assembling every major component. Covered areas include wheels, spindles and rear axle, brake system, steering system, suspensions, hoist circuit, operator cab, body and structures, three-phase wheel motor, power module, auto lubrication system, main blower, retarding grid, and control cabinet. Tightening torques and component weights are included throughout.

90 Diagrams and Drawings

What This Komatsu 860E-1KT Shop Manual Enables You to Do

This manual gives you the full factory service information for the 860E-1KT dump truck. You can diagnose electrical faults using the extensive fault code tables, troubleshoot hydraulic problems with the circuit diagrams, perform complete brake and suspension servicing, remove and install the wheel motors, rebuild the hoist cylinders, service the steering system, and maintain the AC drive system with the SiBAS® control architecture. Every procedure is written with the specifications, torque values, and wear limits needed to do the job correctly.

Having the correct shop manual for a Komatsu 860E-1KT is essential for safe and efficient maintenance. The truck’s systems are complex and tightly integrated — from the 24V control network to the high-voltage AC drive and the hydro-pneumatic suspension. Using the wrong procedure or an incorrect torque value can lead to component damage, downtime, or safety incidents. This manual removes the guesswork and provides the exact information required for each task.

Whether you are performing a routine 500-hour service, diagnosing a fault code, overhauling a wheel motor, or rebuilding the hoist circuit, this Komatsu 860E-1KT service manual is the single most important reference for the job.
