The repair and replacement
standards included herein give the minimum,
maximum, and key clearances of new parts. The
standards also give wear limits which indicate the
extent to which a part or parts may be worn before
replacement, in order to receive maximum service with
minimum replacement. Normally, all parts which have
not been worn beyond the dimensions shown in the
“Wear Limits” column, or damaged by corrosion, will
be approved for service. An asterisk (*) in the “Wear
Limits” column indicates that the part or parts should
be replaced when worn beyond the limits given in the
“Size and Fit of New Parts” column. In the “Size and
Fit of New Parts” column the letter “L” indicates a
loose fit (clearance) and the letter "T" indicates a tight
fit (interference).
