Rear Cover
Note Wiring
Position
Capacitor Housing
Remove the capacitor from its housing. Take note of the
connections and then remove from motor.
Warning! Care should be taken when handling capacitors.
Unscrew the bolt from the rear cover using a ring spanner
(13mm) and remove the cover. Note that it has a gasket
on the inside. Check for damage and replace if necessary.
3.
4.
Remove the floating neck ring from the impeller and with
a flat blade screw driver break the plastic tab blocking the
impeller nut.
Tap the pump foot towards the rear with a soft head
mallet. This makes it easier to unscrew the locking nut
using the large Silensor spanner (part 13810SP). If the
spanner is tight hit the spanner with a sharp tap of the
mallet to free up the nut.

Balance
Drum Ring
Myler
Washer
Using a flat blade screwdriver in the slot at the rear of the
motor to hold the rotor steady and an Allen key (10mm) in
the impeller nut unscrew the impeller in an anti-clockwise
direction.
Mechanical
Seal
Remove the mechanical seal & Myler Washer located
beneath the mechanical seal from the impeller. If the
unit is fitted with a balance drum ring then remove it and
discard as it is no longer required. This was fitted up to
serial number 07078-8046.
7.
8.
Hold the front of the motor and gently tap the foot to slide
off the outer casing and expose the rubber baffle.
The rubber baffle can be removed by peeling it off from
the split on the underside of the motor.
9.
10.
Remove the power lead from the non drive end shield,
then tap the motor shaft with a soft head mallet to remove
the stator assembly from the casing.
With the small Silensor spanner (Part 13810-1SP) undo
the locking nut at the rear of the motor and remove. You
might have to hit the spanner with a sharp tap of the
mallet to free up the nut.

12.
Sealing Ring
O-ring
Slinger
To remove the rotor and perform a bearing change
remove the slinger, O-ring and the front sealing ring in
that order.
Tap off the non drive end shield taking care not to damage
the wiring. Move the power cord out of its recess to a safe
position before proceeding to the next step.
13.
14.
Remove both bearings from the rotor but only replace the
non drive end bearing.
With a heat gun, heat this area turning the stator shell so
as not to blister the paint. After approximately 2 minutes
you should be able to tap out the rotor or push it out using
the bearing press.
15.
16.
With the aid of the new bearing tool place the other
bearing on top and place the tool under the bearing press.
Slide the stator and shell down over the bearing tool and
press it down until the bearing is seated correctly in the
stator shell.

18.
17.
Replace the front sealing ring, O-ring, and slinger. The
motor is now ready for reassembly.
Remove the stator and shell and turn upside down on the
small bearing tool then place back under the press. Insert
the rotor being careful of the windings and then press it
into the bearing with the press.
19.
20.
The diffuser should be inside the front casing simply pull it
out and check for distortion and also check the O-ring that
is on the inside.
Note: The SLS front casing has a removable rubber flap
valve, the SLL has not.

Re-assembly
Procedure
2.
1.
O-ring
Note: It is a good idea to
have a hole in the work
bench to be able to stand
all motors on end.
Fit the O-ring to the casing and then insert the
assembled stator and rotor into it with the motor leads at
approximately 1 o’clock to the slot at the bottom of the
casing.
Place the motor shaft down through a hole in the work
bench and stand the unit on end. Next replace the end
shield by bringing the stator wires through the slot in the
end shield while the other slot should line up with the cut
out in the casing.
3.
4.
Replace the large case nut and bring the power lead
through it .
Bring the power lead out through the bottom slot and
push it into the cut out in the casing thread now you
can replace the casing nut and tighten it with the small
Silensor spanner (part 13810-1SP).
8
5.
6.
Slide the outer cover down over the assembly so that the
slot lines up with the slot in the casing and the power lead
comes through.
Replace the rubber cover with the flanged end down
and lock it into the slot in the casing with the power lead
running down the middle.
7.
Myler
Washer
8.
Mechanical
Seal
Stand the assembly on its foot. Use a single drop of
Loctite 401 on the shaft, secure the shaft with a flat
blade screw driver at the non drive end and screw on the
impeller by hand or with the aid of a 10mm Allen key in a
clockwise rotation. Do not over tighten.
Place the mechanical seal back into position on the
impeller ensuring that the Myler Washer is located
beneath it.
10.
9.
Fit the diffuser complete with O-ring into the front casing
with the lug on the diffuser at the top.
Replace the floating neck ring on to the impeller and also
fit the casing O-ring.
9
12.
11.
With the pump facing you place the front casing against it
and turn the casing nut anti clockwise to lock it in. There
are two slots in the motor casing that the front casing
locks into.
13.
Tuck all wires into the capacitor cover and then fit the rear
cover complete with gasket and tighten the bolt using a
ring spanner (13mm). The pump is now ready for water
testing.
10
Use the large spanner to tighten the nut. Be aware that
there is a lug on the nut that should not finish at the top
as it can interfere with the barrel union on the SLS model
