DISASSEMBLY

Remove the four acorn nuts 3/8” (10 mm) (Key 1) and

fiber washers (Key 2) from the pump studs (Key 3). Slide

the macerator adapter (Key 4) off the studs. Insert a thin

bladed 9/32" (7mm) ignition wrench behind the chopper

plate (Key 6) and onto the flat of the motor shaft to

prevent it from turning. Unscrew (counter-clockwise) the

locknut 7/16” (11 mm) on the end of the motor shaft and

remove the stainless steel chopper blade.

†

Remove the

pump wearplate (Key 7) and two paper gaskets (Key 8).

Now slide the pump body (Key 12) with impeller (Key 9),

small wearplate (Key 10), two studs and shaft seal as an

assembly off the motor shaft and remaining two

mounting studs. Remove the starlock retaining washer

on the seal and push the seal out of the seal bore.

If reconditioning pump with a service kit (Part No.

18598-1000), it is not necessary to remove the seal

because the new seal is pre-installed in the new body. It

is also generally not necessary to remove the slinger or

brass studs screwed into the motor end bell.

ASSEMBLY

If installing a new seal, push it into the seal bore of the

body with the lip pointing toward the impeller bore.

Press the starlock washer into the seal bore with the

concave side up to secure the seal in the bore. Install the

two shorter studs in the two holes with threaded inserts

in the new pump body and tighten finger tight. If

required, screw the two longer studs into the tapped

holes in the motor end bell. Slide the new pump body

with the shaft seal installed onto the motor shaft and two

long mounting studs in the motor. Slide the small

wearplate over the motor shaft and position it in the

bottom of the impeller bore. Slide the new impeller onto

the motor shaft and, with a counter-clockwise motion,

push it into the pump impeller bore. Position one new

gasket on the studs and against the pump body

assuring the cut-out aligns with the inlet groove in the

body. Position the large wearplate and second gasket on

the studs and against the body again aligning the hole in

the wearplate and gasket cut-out with the pump inlet.

Position the chopper on the end of the motor shaft with

drive tab aligned with flat of shaft and pointing toward

the motor. Hold the shaft with the ignition wrench and

secure the chopper to the shaft with the locknut.

position the macerator housing on the four studs

ensuring the cut-out in the inner wall aligns with pump

body inlet port and hole in the wearplate. Position a new

fiber washer on each of the studs and secure the

macerator housing in place with the four acorn nuts.
