It details the Hydrair II suspension cylinders at each wheel, the full-time power steering system with nitrogen-charged accumulators, the all-hydraulic wet disc service brake system, the spring-applied hydraulically-released parking brake, and the dynamic retarding system. It also includes the VHMS (Vehicle Health Monitoring System), Payload Meter III, and the complete electrical and hydraulic schematics.

What This Shop Manual Enables You To Do

This Komatsu 930E-4 Dump Truck Shop Manual supports the full range of service work on the 930E-4 — from routine maintenance and scheduled service to component-level disassembly, repair, and reassembly. It provides the procedures, specifications, torque values, service limits, and diagnostic steps needed to properly maintain and repair the engine, electric propulsion system, hydraulic system, brake circuit, suspensions, structures, and operator cab. The manual’s section-based organization covers each major serviceable area individually, with the disassembly, service, and reassembly of each group discussed as a unit, so a technician can go directly to the system they need without wading through unrelated content.

For a machine as complex as the 930E-4 — with its AC electric drive, wet disc brakes, Hydrair II suspensions, and VHMS electronics — using the correct procedures and specifications is not optional. This shop manual provides the exact torque values, pressure settings, clearances, adjustment values, and step-by-step sequences that keep the truck operating safely and efficiently, and helps prevent costly damage from incorrect service methods.
