Replacing the Conveyor Motor and Crank Disk
In this procedure, you replace both the conveyor motor and the crank disk that propels the motion of the conveyor rake fingers.
It is recommended that you perform the procedures in this document on a stable flat surface that is large enough to securely
and safely hold the Simply Clean
®
Litter Box unit, and that provides sufficient work area for you to work with the individual
components.We also recommend you remove the litter in the bowl as part of this procedure.
Requirements
To complete the procedures in this document, you need:
• A #1 Philips screwdriver
• A flat head screwdriver (optional)
• A replacement conveyor motor kit

Removing the Conveyor Motor
Cover the work surface with a large sheet, drop cloth, or
newspaper, and then:
1. Remove the conveyor cover and set it aside
(see Figure 1 below).
Figure 1: Removing the conveyor cover
2. Loosen the two thumbscrews that secure the
conveyor to the base (see Figure 2 below) .
Figure 2: Loosening the thumbscrews
3. Carefully lift up on the
conveyor, until it rests in
an upright position
(see Figure 3 below).

an upright position
4. Remove the bowl
(see Figure 4 below).
Set the bowl aside.

the bowl
5. Disconnect the conveyor motor wire from the base.
Press in on the middle of the clip to release the locking
mechanism. If the clip does not easily release, use a flat
head screwdriver to gently press in at the center of the clip.

6. Remove the conveyor from the base unit by lowering the
conveyor to its natural position first. Next, lift up on the
non-motor corner of the conveyor until the retaining arm
extending down from the conveyor is free from the base
assembly, and then lift the conveyor off the base unit. Set
the conveyor on the work surface.
Figure 6: Removing the conveyor
7. Remove the motor from the conveyor.
a. Use a #1 Philips screwdriver to remove the retaining
screws and brackets securing the motor to the conveyor
(see Figure 7 “A” below). Set the screws and brackets
aside to be used to attach the new motor.
b. Lift up on the motor to free the motor turn shaft from
the crank disk (see Figure 7 “B” below).

Replacing the Crank Disk
Turn the conveyor over to expose the crank disk, and then:
1. Rotate the drive shaft until it is fully extended above the
underside of the conveyor (see Figure 8 below).
Figure 8: Positioning the drive shaft
2. Lift up on the drive shaft and rotate the crank disk
toward the center of the conveyor assembly. Twist the
bottom of the crank disk towards the drive shaft and then
slip it off the end of the shaft (see Figure 9 below).
Figure 9: Removing the crank disk
NOTE: If a rake finger detaches from the drive shaft, hold the
drive shaft steady while gently pressing the rake finger against the
shaft to snap it back into place.
3. Attach the replacement crank disk to the drive shaft.
Align the crank disk with the inside surface towards the
drive shaft.
a. Lift the rake-finger assembly up to elevate the drive
shaft above the conveyor assembly, and attach the
crank disk to the drive shaft by inserting the exposed
end of the drive shaft into the open channel on the
crank disk (see Figure 10 “A” above).
b. Push the crank disk up and around until it
is perpendicular to the drive shaft (see Figure 10
“B” and “C” above).

Installing the Replacement
Conveyor Motor
To attach the motor to the conveyor:
1. Position the crank disk half-circle hole with the opening
on the side of the conveyor assembly (see Figure 11
below).
2. Insert the conveyor motor’s drive shaft into the half-circle
hole on the crank disk (see Figure 12 below). Both the
crank disk and motor drive shaft align correctly for a
matched fit.

3. While holding the crank disk up so it does not detach
from the motor drive shaft, turn the motor assembly until
the two flanges are properly aligned with, and fitted to the
posts on the conveyor assembly (see Figure 13 below).

4. Secure the conveyor motor in place with the two plastic
retaining brackets. Attach the semi-circle side towards
the conveyor motor for both brackets. (see Figure 14
below). Replace the screws and tighten with a #1 Philips
screwdriver.

5. Reattach the conveyor assembly to the base unit. First,
insert the plastic post on the motor side of the conveyor
into the cutout on the base unit. Next, then apply gentle
pressure to the retaining arm on the opposite side of the
conveyor while you insert it in the cutout on the other
side of the base unit (see Figure 15 below).

6. Move the conveyor to its upright position, and then
reconnect the conveyor motor wire to the base (see Figure
16 below). Press down until the catch clicks into place.

7. Flip the base over, move the conveyor to its upright
position, and then place the bowl back onto the base unit
(see “A” in Figure 17 below). Be sure to adjust your litter
guard so that the conveyor fits within the notch on the
guard (see “B” in Figure 17).

8. Lower the conveyor into place (see Figure 18 below).
If your bowl is full of litter, you may gently wiggle the
conveyor back and forth to bury the rake fingers in
the litter.
9. Tuck the motor wires into the space between the conveyor
assembly and the base unit so they do not get pinched
between the two. Tighten the two thumbscrews to secure
the conveyor to the base (see Figure 19 below).

Testing Your Simply Clean
®
Litter Box
To verify that your repair was completed correctly:
1. Replace the conveyor cover and waste receptacle. Both
have to be in place for the unit to work properly.
2. Plug the unit into the power source.The Operating
Indicator LED should illuminate.
3. Without lifting up on, or removing the conveyor cover,
observe the area at the base of the conveyor for conveyor
movement.
If your conveyor is not moving:
• Make sure the conveyor cover is securely in place and the
waste receptacle is completely installed in its bay.
• Loosen the thumbscrews and lift up the conveyor to verify
that the motor connector is completely and properly
attached to the base unit. (see page 3, Figure 16 for
reference).
