11.0 Fastener Torque Requirements
NOTICE: No pump service procedure is complete without ensuring that the fasteners
have been properly torqued. Failure to properly tighten the pump bolts could cause the
pump to leak or fail. Always use a calibrated torque wrench during the installation of all
critical fasteners listed in Table 6 below. Values are in foot-pounds (Ft-lb) and Newton
meters (N-m). Typical sizes are shown in Table 6 below. Refer to Table 7 for other sizes
that may be used depending upon application.
