Section IV. REPAIR AND REPLACEMENT STANDARDS
(MODEL T-136-27)
4-16. General.
The repair and replacement
standards included herein provide the minimum,
maximum, and key clearances of new parts. (See fig.
4-22, 4-23, 4-24, and 4-25 and corresponding tables 4-
1, 4-2, 4-3, and 4-4.) Standards also provide wear
limits which indicate the point to which a part or
parts may be worn before replacement is required, 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” and “Wear Limits”
columns. In the “Size and Fit of New Parts” and
“Wear Limits Columns”, the letter “L” indicates a
loose fit (clearance) and the letter "T" indicates a tight
fit (interference).
