casing bore or binding and/or excessive
wear will result.
Replace the suction cover gasket (39). Position the
suction cover over the studs (37) and secure the
suction head to the pump casing using the nuts
(38). Make sure the jacking screws (33) do not in-

Final Pump Assembly
Be sure the pump assembly is securely mounted

tight, properly supported and secure.
Be sure the pump and power source have been
properly lubricated, see LUBRICATION.
Refer to OPERATION, Section C, before putting
the pump back into service.

seal (see Figure 5).
