Generously lubricate the back cover O-rings with No. 2 grease. Remove and clean
all debris or scale from the pump casing contact surfaces. This could interfere with
or prevent a strong seal with the back cover.
Locate and loosen the 2 hand adjusting knobs in the back coverplate until they are
even with the backside, machined surface of the coverplate.
Accurately position the back coverplate over the 4 studs then slide it into the pump’s
casing. Use two diagonally positioned hand nuts that are opposite each other for
pushing the back cover into the pump casing. Be sure the wearplate barely touches
the impeller when the shaft is turned by hand then tighten the hand nuts equally to
keep them from binding.
