Service
Clean out the pump body, if
necessary, examine wear ring (13)
and replace if worn. If the wear ring
requires replacing, split the wear ring
and remove, be careful not to
damage the suction cover (16). Clean
and examine impeller (7) for pitting
or wear, replace if required.
To remove impeller (7), remove screw
(10) (or nut), lockwasher (9) and
impeller washer (8). The impeller is
keyed onto the shaft with a square
shaft key and to remove, pull impeller
straight off the shaft using a wheel
puller if required. Inspect gasket (15)
if suction cover (16) has been
removed, and replace if cut or
damaged. Before reinstallation, check
the motor shaft and impeller bore for
damage.
Reassembly -
To install wear ring (13)
first apply retaining compound to the
bore of suction cover (16) and then
press wear ring (13) into bore of
suction cover (16) until seated.
Position gasket (15) on volute, and
locate suction cover (16) on volute
(12), apply thread locking compound
to socket head screws (17), and
tighten into volute (12).
To install impeller (7), apply a thin
film of oil to motor shaft and slide
impeller straight onto shaft, keeping
keyways lined up. Drive shaft key into
keyway.
Install impeller and motor assembly
onto volute (12). Apply thread
locking compound to threads of each
cap screw (2). Position lockwasher (2)
on cap screws (2) and torque to 24
ft/lbs. Check for free rotation of
motor and impeller.
Locate impeller washer (8) on shaft,
apply thread lock primer (such as
LOCTITE® Primer T), let set per
manufacturer’s directions, to screw
(10) threads, thread screw (10) into
shaft and torque to 35 ft/lbs. Rotate
impeller to check for binding.
