(8) Carefully place the motor stool (163) over the pump shaft and the tie rods and onto the outer
casing.
(9) replace the tie rod washers and nuts onto the tie rods finger tight.
(10) Commence staggered tightening of the tie rod nuts to ensure even distribution of pressure and
proper seating of the motor bracket onto the pump casing (007). Tighten all nuts to fit snugly.
See torque specifications, page 21.
(11) Carefully install the new cartridge seal over the pump shaft and into the top of the pump being
sure that it is firmly seated. re-install the four retaining bolts (120-3) that secure the cartridge
seal to the pump and tighten the three setscrews in the locking collar.
(12) reinstall the spacer coupling. Thread the hex head bolts (120-5) back through the top of the spacer
coupling loosely so it is supported but do not fully tighten. Be sure that the cross key is aligned
with the keyway in the bearing assembly above. Spin the spacer coupling so that hole in the
pump shaft is aligned with hole in the rear of the spacer coupling.
(13) reinstall the shaft pin (131-1) through the hole in the pump shaft making sure that it seats in the
blind hole in the back of the spacer coupling. Once the shaft pin has been installed and the
pump shaft and spacer coupling are engaged via the shaft pin, install the front half of the spacer
coupling and install the two socket head bolts (120-6) that secure it.
(14) Firmly tighten the four hex head bolts (120-5) that secure the entire spacer coupling to the upper
coupling and bearing assembly above being sure that the drive key is positioned correctly so that
these parts are properly engaged with each other.
The working length of the seal is set by completion of this step. There is no other adjustment
that needs to be made to the seal.
(15) reattach the coupling guards to each side of the pump and then reinstall the motor to complete.
(16) refer to section 5B for motor installation instructions.
