11.0 Fastener Torque Requirements
NOTICE: No pump service procedure is complete without insuring that the fasteners
have been properly torqued. Failure to properly tighten the pump bolts could cause the
pump to leak or possibly allow the pump to fail. Always use a calibrated torque wrench
during the installation of all critical fasteners listed in Table 5 below. Values are in foot-
pounds (Ft-lb) and newton meters (N-m). Typical sizes are shown in Table 5 below.
