On motor sizes 213TC and 215TC, place motor hub to over-
hang motor shaft by 5/16”.
On motor sizes 254TC and 256TC, place motor hub flush with
the end of the motor shaft.
On motor sizes 284TSC and 286TSC, place motor hub to
overhang motor shaft by 3/16”.
On motor sizes 324TSC, 326TSC, 364TSC and 365TSC,
place motor hub flush with the end of the motor shaft.
ah) On motor sizes 143TC, 145TC, 182TC and 184TC, bolt the
spacer section to the motor hub.
ai) Place the coupling elastomer into the pump coupling hub.
aj) Lift the motor and motor support (83) assembly with a hoist,
and position it so that the motor support pilots onto the end of
the bearing housing (26) and so that the motor end of the cou-
pling engages the coupling elastomer that is retained in the
pump hub of the coupling. It may now be necessary to rotate
the motor shaft slightly to allow the coupling components to
engage. Install the bolts that retain the motor support (83) to the
bearing housing (26). Hand tighten the bolts.
ak) Remove all blocks and wedges while maintaining support with
a hoist. Gently and carefully lower the hoist enough to allow
the weight to seat the supporting feet onto the baseplate. When
the support feet make full contact with the base, lightly tighten
the casing stud nuts (5C) and the bolts that retain the motor sup-
port (83) to the bearing housing (26).
al) Tighten the casing stud nuts (5C) evenly to 105 ft. lb.
am) Tighten the motor support (83) to bearing housing (26) bolts to
65 ft. lb.
an) Bolt the pump assembly to the baseplate, at the motor support
foot (9) for motor sizes 143TC through 215TC, or at the rear
two feet of the motor for motor frames 254TC through 365TSC.
ao) Rotate the pump shaft by hand to check for rubbing or binding.
Go to step at).
ap) Gently allow the hoist to lower the pump assembly until the
weight of the unit seats the bearing housing foot (9) firmly
against the base plate. Tighten the casing stud nuts (5C) evenly
to 105 ft. lb.
aq) Bolt the bearing housing foot (9) to the baseplate.
ar) Rotate the pump shaft by hand to check for rubbing or binding.
as) Align the pump and driver shafts. See “Pump and Driver
Alignment”. Reinstall the coupling spacer.
at) Reinstall the coupling guard(s).
au) Lubricate the pump according to the “Pump Lubrication” instruc-
tions.
av) Reinstall any auxiliary piping and drain plugs that were
removed during disassembly.
aw) Remove tools, old parts and debris from the area around the
pump.
ax) Follow “Starting the Pump” instructions to restart the pump.
