INTRODUCTION
The specifications given in this chapter are on the basis
of information available at the time the book was
written. These specifications give the torques, operating
pressure, measurements of new parts, adjustments and
other items that will affect the service of the product.
When the words "use again" are in the description, the
specification given can be used to determine if a part
can be used again. If the part is equal to or within the
specification given, use the part again.
When the word "permissible" is in the description, the
specification given is the "maximum or minimum"
tolerance permitted before adjustment, repair and/or
new parts are needed.
A comparison can be made between the measurements
of a worn part, and the specifications of a new part to
find the amount of wear. A part that is worn can be safe
to use if an estimate of the remainder of its service life
is good. If a short service life is expected, replace the
part.
NOTE:
The specifications given for "use again" and "permissible" are Intended for guidance only and
Caterpillar Tractor Co. hereby expressly denies and excludes any representation, warranty or
implied warranty of the reuse of any component.
