    GENERAL INSTRUCTIONS

    Use bolts of the correct length. A bolt which is too long may "bottom" before the head is tight against the part it is to hold, and in addition the threads may be damaged when the bolt is removed.

    If a bolt is too short, there may not be enough threads to hold the part securely.

    Lockwashers, cotter pins or flat metal locks should be used to lock each nut and bolt. Flat metal locks must be installed properly to be effective. Bend one end of the lock sharply around the edge of the part. Bend the other end sharply against one flat surface of the nut or bolt head. Do not bend the lock against more than one side of the nut.

    DECIMAL EQUIVALENTS

    The decimal dimensioning system provides a more accurate means of specifying dimensions and toler-ances .The following table includes the standard con-versions from fractions to decimals. Decimals are shown in the standard two, three and four place des-ignation. ~;"

    METHOD FOR LOCK POSITIONING AND BENDING

    When assembling a machine, complete each step in turn. Do not leave one part partially assembled and start assembling some other part. Make all ad-justments as recommended. Always check the job after it is completed to see that nothing has been overlooked.

    PREPARATION FOR STARTING

    After assembling a machine, lubricate it thor-oughly. Fill the various compartments with the type and grade of lubricant recommended in the Opera-tion and Maintenance Instructions.

    Recheck the various adjustments by operating th.e machine before returning it to the job.

    TORQUE VALUES

    Unless reference is made in the copy to the topic, SPECIFICATIONS, the standard torque values listed in the chart should be used for standard heat-treated bolts and studs and steel nuts when assembling Caterpillar Equipment.
