DESCRIPTION:
Komatsu 930E-3 Dump Truck Shop Manual
This Shop Manual is written for use by the service technician and is designed to help the technician become fully knowledgeable of the truck and all its systems in order to keep it running and in production. All maintenance per- sonnel should read and understand the materials in this manual before perfomiing maintenance andlor operational checks on the truck. All safety notices, warnings and cautions should be understood and followed when accomplishing repairs on the truck.
- The first section covers component descriptions, truck specifications and safe work practices, as well as other gen- eral infomiation. The major portion of the manual pertains to disassembly, service and reassembly. Each major serviceable area is dealt with individually. For example: The disassembly, service and reassembly of the radiator group is discussed as a unit. The same is true of the engine and engine accessories, and so on through the entire mechanical detail of the truck.
- Disassembly should be carried only as far as necessary to accomplish needed repairs. The illustrations used in this manual are, at times, typical of the component shown and may not necessarily depict a specific model. This manual shows dimensioning of U.S. standard and metric (SI) units throughout and all references to “Right”, ‘Left“, ‘Front’, or “Rear” are made with respect to the operator’s normal seated position, unless specifically stated othemise.
- Standard torque requirements are shown in torque charts in the general information section and individual torques are provided in the text in bold face type, such as 100 ft.lbs. (135 Mm) torque. All torque specifications have ae10% tolerance unless otherwise specified. A Product Identification plate is nomially located on the truck frame in front of the right side front wheel and desig- nates the Truck Model Number, Product Identification Number (vehicle serial number), and Maximum G.V.W. (Gross Vehicle Weight) rating.
- The KOMATSU Truck Model designation consists of three numbers and one letter (i.e. 930E). The three numbers represent the basic truck model. The letter “M’ designates a Mechanical drive and the letter “E’ designates an Electrical propulsion system.
- The Product Identification Number (vehicle serial number) contains information which will identify the original man- ufacturing bfll of material for this unit. This complete number will be necessary for proper ordering of many service parts and/or warranty consideration.
