What This Komatsu 930E-4SE Shop Manual Lets You Do

With the complete Komatsu 930E-4SE Dump Truck Shop Manual CEBM027101 in hand, you can perform the full range of scheduled and unscheduled maintenance on the truck without guessing. The manual covers the AC electric drive system end to end, including the alternator field control, both inverters, the gate drive power converters, the retarding grid chopper circuits, the traction motorized wheels and the event detection and troubleshooting logic that keeps the truck moving. It also covers the Hydrair II suspensions front and rear, the wet disc service brakes and spring-applied parking brakes, the full hydraulic system from the pump module through the hoist valve and brake cooling circuits, the diesel engine power module, the 24 VDC non-propulsion electrical system, and the operator cab with its heater and air conditioner. You get the torque values, pressure settings, clearances, shim calculations, wheel bearing adjustment procedures, accumulator charging pressures, suspension oiling and nitrogen charging dimensions, and the wiring and hydraulic schematics needed to trace a fault to its source.

Every section in this 930E-4SE shop manual follows the same pattern: component description, removal, installation, disassembly, cleaning and inspection, assembly, testing and troubleshooting. That means whether you are resealing a hoist cylinder, replacing a wet disc brake, setting wheel bearing preload, rebuilding a steering cylinder, charging a suspension accumulator or diagnosing a propulsion system fault code on the DID panel, the procedure is laid out in order with the specifications you need at each step. The 1,366-page Komatsu 930E-4SE service manual is the reference that keeps a 505,611 kg haul truck running safely and productively.
