Komatsu 730e Dump Truck Workshop Service Repair Manual
FOREWORD :
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 personnel should read and understand the materials in this manual before performing maintenance and/or 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 general information. 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 otherwise.
- 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 N.m) torque. All torque specifications have ±10% tolerance unless otherwise specified. A Product Identification plate is normally located on the truck frame in front of the right side front wheel and designates 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. 730E). 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 manufacturing bill of material for this unit. This complete number will be necessary for proper ordering of many service parts and/or warranty consideration.
ENGINE: The KOMATSU 730E Dump Truck is powered by a Komatsu SSA16V159 engine rated at 2000HP (1492 kW).
ALTERNATOR: (GE GTA-22) The diesel engine drives an alternator mounted inline with the engine. The alternating current (AC) output of the alternator is rectified to direct current (DC) and sent to the DC drive wheel motors.
WHEEL MOTORS :(GE 788) The output of the alternator supplies electrical energy to the two wheel motors attached to the rear axle housing. The two wheel motors convert electrical energy back to mechanical energy through built-in gear trains within the wheel motor assembly. The direction of the wheel motors is controlled by a forward or reverse hand selector switch located on a console to the right side of the operator.
BLOWER: The blower supplies cooling air for the rectifiers, AC alternator, and to both wheel motors, where it is then exhausted to atmosphere.
