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.
