Place the rear housing (2) on the center
housing (21).
NOTE: Make sure the rear housing seats properly over
the alignment pins. If the rear housing has an Internal
Bearing Flush (IBF) groove, the groove must be on the
discharge side of the pump (see bottom of Page 20).
12 Install four sets of bolts (4), nuts (29)
and lockwashers (30) into the housing;
then tighten the bolts.
NOTE: Apply anti-seize compound to the bolts. Refer to Appendix 1 for the torque specifications of the fasteners.
When tightening the housing bolts, use a star pattern torque sequence on the fasteners to ensure even compression
on the O-ring's surface. With Teflon O-rings, repeat this process several times, waiting between retightening. This
is necessary because the Teflon will cold flow and require a certain amount of time to properly seat. Continue the
process until the bolts no longer require retightening.

containment can O-ring (19) into the
circular groove on the front housing.
CAUTION! Do not reuse O-rings.
