HOW TO USE THE 951B TRAXCAVATOR SERVICE MANUAL
The Service Manual is divided into five parts. Although all are related, each part can be used to fulfill a specific need. Use of one part or the complete manual will depend on the problem facing the serviceman, his knowledge of the machine and its service procedure.
PART I is Lubrication and Maintenance Information. In it is the booklet which was also included with the machine. It is provided with the manual as a source of information concerning types of lubricant, capacities and adjustment procedures.
PART II is Systems Operation which includes a thorough discussion of the way each system in the machine works. This is divided into four sections: Engine, Power Train, Chassis and Loader Portion. These sections have a further breakdown designated by a number in the upper right corner of each page. This number provides a means of identifying a page, should a revised or new page insertion become necessary. The number also serves as a page location for listing in the Table of Contents.
PART III, Testing and Adjusting, includes information necessary to troubleshoot a particular system within the machine. This is sectionalized in the same manner as Systems Operation.
PART IV, pictorially disassembles and assembles machine components. A Service Guide in each section illustrates, in chart form, the steps necessary to remove a component not immediately accessible. Numbers are used on some illustrations to indicate the sequence of disassembly If the disassembly or assembly sequence is obvious, the numbers are omitted. A circled number on an illustration, with or without a prescribed sequence, indicates that a specific procedure is necessary to disassemble or assemble The information will appear adjacent to or on the page opposite the illustration. Adjustment procedures which are required at assembly time; ie, bearing clearance, bearing
preloads, are shown in the Disassembly and Assembly part. If however, an adjustment procedure is part of a maintenance or troubleshooting function the symbol for adjustment will be used. The adjustment procedures will be given in the Lubrication and Maintenance Information or Testing and Adjusting part. General Instructions, a review of many items which a mechanic encounters in servicing machines, are included in the Disassembly and Assembly part Proper installation of lip-type seals, Duo-Cone floating seals and locks are examples. These items are covered in topic form so a specific subject can be located quickly.
PART V, Specifications, is an illustrated listing of tolerances of new parts, pressures, adjustments, torque values, etc Maximum and Minimum tolerances are listed in some instances. These are reasonable figures to use in determining when to replace parts.
