         NUT AND BOLT TORQUING

            It  is important to  apply the proper  torque to  all  bolts/nuts  used  on  the
          cylinders to prevent distortion, damage to the components,  and  breakage
          of the castings. This is particularly important on the valve jam  screw  and
          valve cover bolting.

          INSPECTION  FORMS

            It is important that forms  are available at the time of inspection so that
          the  measurements  taken may  be  immediately  recorded. Topical  inspec-
          tion forms for compressor cylinders are shown in Figure  4-20.
