b) Inspect the suction manifold for internal erosion and corrosion. Remove the three suction
manifold o-ring seals and inspect the seal grooves in the manifold for erosion and corrosion.
Inspect the face and O.D. of the pipe at each end of the manifold for erosion and corrosion.
Note: The MSI manifold incorporates a Victaulic “ES” type connection at each end which will
accept either a Victaulic “End Seal Cut Groove: gasket or a Victaulic “Standard Cut Groove”
gasket.
c) The condition of the pipe face at each end of the manifold is important for sealing purposes only
when the “End Seal” (ES) gasket is used.
d) Inspect the bottom face of the fluid cylinder for erosion and corrosion. Thoroughly clean and
lightly hand polish the bottom face of the fluid cylinder with a 220 to 240 grit Emery cloth prior
to reinstalling the suction manifold.
e) Using new o-ring seals, reinstall the suction manifold. Reinstall the twelve ¾” cap screws and
evenly tighten them to the proper torque (Appendix 9.20).
6.80 Removing the Fluid End
a) Remove Plungers and Packing as outlined in Section 6.30 .
b) Remove the four (4) 1” bolts and the four (4) 1 3/8” bolts, which secure the fluid cylinder to the
Power Frame. Remove the fluid cylinder from the Power Frame. *Note that the fluid cylinder
is only secured by these 8 bolts and must be supported before the bolts are removed.
c) Examine the mating surfaces of the fluid cylinder and nose plate for signs of damage. Examine
mounting bolt threads for signs of damage. Repair or replace as necessary.
d) Clean and lubricate the fluid cylinder mounting bolt threads with DOW CORNING G-n Metal
Assembly Paste.
e) Reconnect all hose and piping connections and tighten plunger to crosshead to torque of 300
ft-lbs.
