Safety Information

Failure to act in accordance with the following may result in death, serious injury,

coach or property damage.

The In-Wall® Slide-Out System is intended for the sole purpose of extending and retracting the slide-out room. Its
function should not be used for any purpose or reason other than to actuate the slide-out room. To use the system
for any reason other than what it is designed for may result in death, serious injury or damage to the coach.

Before actuating the system, please keep these things in mind:

1. The unit should be parked on solid and level ground and the area around the unit clear of obstructions
that may cause damage when the slide-out room is being repaired.

2. Be sure all persons are clear of the coach prior to the slide-out room maintenance.

3. Keep hands and other body parts away from slide-out mechanisms during actuation.

Preliminary Visual Inspection

Prior to conducting any repair or replacement, it is imperative to ensure that the problem with the slide-out is
properly diagnosed and that the issue will be corrected with a repair or replacement. Proper diagnosis of the issue
includes ruling out a slide-out obstruction, a slide-out seal issue, or a slide-out measurement that is outside of
suggested parameters. Prior to slide-out repair or replacement, be sure to check the following:

1. Check assembly and slide room for any type of obstruction that may have caused the initial concern.

2. Inspect the wiper seals for tearing or other damage.

3. Make sure that the wiper seals are not being pulled into the gear rack causing binding.

4. Check that the interior and exterior bulb seals are compressing properly when the slide-out is

extended or retracted.

5. It is recommended that measurements be taken to make sure the gear racks are parallel and that the
C-Column is square. Make sure the measurements are taken from the same location at both ends of
the gear racks (Figs. 1 and 2).

6. Measure from the outside edge of the clamp strap to the face of the slide room wall. Variance could be
up to +3mm or -1.5mm (Fig. 3).

NOTE: LCI prefers to have these measurements submitted in picture format to assure proper guidance is

given.

Assembly Removal Procedure

Tools Required

• Electric drill or cordless screw gun

• Rubber mallet

• 2x4 (length=gap between T-molding and side of unit-¼”)

• Razor knife

• Screw jack

Procedure

NOTE: If the slide will not move by use of the switch it may

be necessary to use one of the three methods (A, B
or C) below:

A. Use electronic override mode on the In-Wall®

controller.
I. Press the “mode button” six times quickly,

press a 7th time and hold for approximately 5
seconds (Fig. 4A).

II. The red and green LED lights will begin to flash

indicating system is in override mode (Fig. 4B).

III. Using the wall switch, press and hold the “IN”

button until the unit comes completely in.

B. Disconnect the motor harnesses from the In-Wall®

controller to allow the slide room to be manually
pushed into position (Fig. 5A).

C. Disengage the motors to allow the slide room to be

manually pushed into position (Fig. 5B).

1. Remove first 3 sets of screws in each rack on the interior
side of slide room.

2. Extend the slide room until about 8" of the room is left
inside the unit.

3. Support the slide room with a screw jack or other
adequate support before continuing.

4. Place the 2x4 block on top of the slide room (standing
on its edge between the T-Molding and side of the unit.)

5. Reach inside the top of the slide column to disconnect
the wiring harness from the motor.

6. Using a razor knife, carefully cut the caulk bead along
the edge of the slide column.

7. Remove the plastic screw cover to access the mounting
screws for the clamp strap. Remove the clamp strap.

8. Create a jumper wire from an extra wiring harness: cut
a 3-foot length of the harness (with the motor wire
connector attached) and strip the ends of the red and
black wires (Fig. 6).

9. Plug the jumper wire into the motor wire.

10. Holding the black and red wires against the terminals

of your cordless screw gun battery, determine which
polarity actuates the motor in the retract direction. The
slide column should slide away from the side of the unit.

12. Carefully slide the ends of the gear racks past the bulb seal on the T-molding.

13. Pull the full system out and set aside.

NOTE: LCI recommends that inspection and repair of the assembly be done on a clear workbench to

prevent further damage to the system.

14. If motor is still in the column, remove at this time. By removing the clamp strap previously, the motor
should be free to move in the column.

Rev: 08.07.18 Page 5 CCD-0001772

Replacement of Entire Assembly Required

Damages listed below will require the inspected system to be replaced with a completely new assembly.

A. Torque Shaft – Inspect the torque shaft for a bow or bend. Also inspect the torque shaft to

assure that it has not dropped. Also make sure the stakes in the top of the torque shaft (Fig. 8)
are adequately keeping the shaft in place. If the torque shaft is found to be faulty, the inspected
system should be replaced entirely.

B. Gibs (Fig. 8A) – In the event that a gib is found to be broken or loose, the inspected system should

be replaced entirely. This includes a broken, loose, or missing rivet.

C. Metal shavings near the spur gear – During inspection of the bearing block it is important to look

for shavings around the spur gear (See locations outlined in Fig. 9A, B, C). This could indicate
excessive wear around the torque shaft caused by the spur gear digging into the torque shaft.

D. “C” Column – In the rare event that the column has been damaged in any way, the inspected

system should be replaced entirely.

NOTE: If replacing the entire assembly, skip to the Assembly Installation Procedure on Page 12.

In-Wall® Gear Racks

Inspection

It will be important to begin with a general inspection of the gear rack to see if replacement is recommended.

Replacement

Below are the steps to replace an In-Wall® Gear Rack:

NOTE: You will notice that included in the In-Wall® Repair Package is an upper and lower gear rack section

that is longer than needed. In this case, a cut will be required to match the size of the original gear
rack.

1. Measure the original gear rack, index your measurement from the “notched” end (Fig. 10A) of the gear
rack and document accordingly.

2. Transfer the measurement taken from the original gear rack onto the new gear rack.

NOTE: Remember to start your measurement from the “notched” end (Fig. 10A) of the gear rack to ensure

proper end of the gear rack is cut.

3. Check measurement prior to cutting.

4. Make the cut to the non-notched end of the rack (Fig. 10B), preferably with a chop saw to prevent

angled cut or “chewed” appearance.

5. De-burr the cut end with a fine file or emery paper.

6. Insert the corresponding foam plugs into each end of the rack to ensure that water infiltration is

prevented prior to installation (Fig. 11 and Fig. 12).

7. Gear racks can now be installed back into the columns.

NOTE: Please refer to the Re-timing Procedure section of this manual on Page 11.

8. If all other concerns have been addressed, assembly can now be installed back on the unit. See

Assembly Installation Procedure on Page 12.

Inspection

A. Damaged or missing shoe: If damage to corresponding foot on bearing block is present,

replacement of the bearing block (Page 10) will be necessary.

Replacement

Below are the steps to replace a shoe (Figs. 13 and 14):

1. With the racks removed from the assembly, the shoe replacement is snapped onto the bearing block
foot. Align the notch located on the foot (Fig. 14A) with the "rib" in the shoe (Fig. 13A) and press into
place.

2. Gear racks can now be installed back into the columns.

NOTE: Please refer to the Re-timing Procedure section of this manual on Page 11.

for bearing block package information.

Rev: 08.07.18 Page 8 CCD-0001772

V-Roller

Inspection

A. Damaged or missing v-roller: If damage to corresponding v-roller arm on bearing block is present,

replacement of the bearing block (Page 10) will be necessary.

B. Stress cracks on or around the v-roller arm: If the v-roller arm is found to be cracked, bent or

unable to accept a replacement v-roller, replacement of the bearing block will be necessary.

NOTE: If damage is evident on either bearing block, BOTH the upper and lower bearing blocks MUST be

replaced.

Replacement

Below are the steps to replace a v-roller (Fig. 15):

1. Remove the corresponding snap ring to allow for removal of damaged v-roller.

2. Inspect v-roller arm for damage. If v-roller arm is damaged, see bearing block replacement

instructions on Page 10.

3. Slide new v-roller onto the v-roller arm.

4. Replace the snap ring (be careful not to spread the snap ring open too far) and inspect for proper

seating.

5. Lube the v-roller bearings with CRC Power Lube with PTFE (Fig. 15 detail).

6. Gear racks can now be installed back into the columns.

NOTE: Please refer to the Re-timing Procedure section of this manual on Page 11.

7. If all other concerns have been addressed, the assembly can now be installed back onto the unit. See

Bearing Block/Spur Gear

NOTE: The bearing blocks do not need to be removed if only the spur

gears are being replaced.

Inspection

A. Stress cracks on or around the bearing block foot or v-roller

arm: If the bearing block foot is found to be cracked or
bent, replacement of the bearing block will be necessary.

B. Excessive damage to spur gear (teeth missing, etc).

Replacement of the spur gear will be necessary.

Spur Gear

Below are the steps to replace a bearing block or a spur gear (Figs. 16, 17, 18):

Bearing Block Rivet

1. If the bearing block shows any type of damage that indicates

repeated contact with the gear rack, it MUST be completely
removed from the drive assembly and replaced. If damage is
evident on either bearing block, BOTH the upper and lower
bearing blocks MUST be replaced.

Fig. 17 Fig. 18

2. Pull the torque shaft up and out from the top of the column,

through both bearing blocks. Be careful not to drop the spur
gears if they are not being replaced, as they will be loose in the
assembly once the torque shaft is removed.

NOTE: If only replacing the spur gears, place the new spur gears into the bearing blocks with the standoff

of each spur gear oriented to the bottom (otherwise bearing block damage will occur) (Figs.
19A/20A). Reinsert the torque shaft from the top of the column back through both bearing blocks
and spur gears. Skip to step 6.

3. Remove the rivets that hold the bearing block in place. These rivets may be made out of aluminum
(Fig. 17) or plastic (Fig. 18) depending on the side being replaced. Remove the bearing blocks.

4. Install the replacement upper and lower bearing blocks and spur gears on the torque shaft and
reinstall the torque shaft assembly into the column. Install new rivets into the bearing blocks.

5. Install shoe and v-roller onto the bearing block assembly after the column is reassembled.

6. Reinstall the gear racks.

7. Reinsert the coupler and motor into the upper bearing block.

NOTE: Please refer to the Re-timing Procedure section of this manual on Page 11.

8. If all other concerns have been addressed, the assembly can now be installed back onto the unit. See

Assembly Installation Procedure on Page 12.

Re-Timing Procedure

The top and bottom gear racks on each side of the In-Wall® Slide-Out System are connected by a torque
shaft that runs from the upper bearing block to the lower bearing block. The bearing blocks and torque
shaft are mounted inside of the column. The column is fastened to the side wall opening of the unit. The
timing of the system from top to bottom is considered to be adjustment free, as it is essentially locked in
correct time. In the instance that the system is no longer in time, either the top or the bottom will extend
farther than its opposite. The following procedure will help to properly address the concern:

NOTE: If the assembly is still on the slide room, refer to the Assembly Removal Procedure on Page 4. If the

assembly is already off the slide room for repair, start at step 1 below.

NOTE: If the system is no longer in time, inspection of all items will need to be performed prior to

proceeding with the re-timing procedure.

NOTE: The re-timing process is made easier by taking the system to a work bench.

1. Pull one of the gear racks to remove it from the bearing block.

NOTE: Both gear racks will move. Be sure when removing the gear racks that they do not fall to the floor or

sustain any damage.

2. Finish pulling the second gear rack free if necessary.

3. When feeding the gear racks back in, start from the notched side. Gently start the gear racks into the

bearing blocks evenly.

4. Once both gear racks are engaged, use a tape measure and measure from the column to the end
of each gear rack. The measurement MUST be the same to ensure that the slide room will be timed
correctly.

5. Apply pressure to one of the gear racks. This will cause both gear racks to move together. At this point,
the gear racks will be back in time.

When reinstalling the system to the slide room, be sure to address the measurements specified in the

Preliminary Visual Inspection section on Page 3. If measurements are not within these specifications,

make necessary adjustments to screw locations to remedy. Adding additional screws may be necessary

in between the pre-drilled spots on the column. If the system is not replaced within those stated

specifications, serious damage to the system may occur.

6. If the above procedure corrects the timing, repeat the same process on the opposite side of the slide, if

necessary.

Rev: 08.07.18 Page 11 CCD-0001772

Assembly Installation Procedure

1. Prepare the slide room and side of unit for the new install by cleaning the surfaces of any adhesive

residue using a putty knife and a solvent. Be careful not to damage the finishes on the unit.

2. Prepare the new system for installation: measure the distance (center to center) from one gear rack to
the next gear rack along the slide column. Write these measurements down.

3. Install all the screws attaching the clamp strap to the C-column.

NOTE: If installing a new assembly, remove the shipping angles before continuing this procedure.

4. Gently slip the system through the opening between the slide room and the side wall opening. Tuck

the gear racks inside the bulb seal attached to the T-molding.

5. Align the bottom lip of the lower gear rack with the bottom edge of the slide room (Fig. 21).

6. Push the bottom gear rack tight against the bottom of the slide room, assuring that the non-notched

end of the gear rack is butted up flush against the interior trim of the slide room. Put a screw into each
end of the gear rack.

7. Measure from the bottom gear rack (center to center)
to the next gear rack and align that rack so that it
matches the measurement taken off of the system
during step 2 (Page 12). This will ensure that the
racks are installed parallel and square. Put a screw in
each end of the gear rack to hold it in place until all
the gear racks are aligned.

8. Once you align and secure all the gear racks, put all
the screws into the gear racks.

9. Attach the jumper wires to the motor in the top of
the slide column and then to the cordless screw gun
battery. Actuate the motor to move the slide column
in towards the coach. Stop it when it is still a few
inches away from the unit. Remove the jumper cable.

10. Make sure the motor cable is tucked into the top of
the slide column.

11. Remove the 2x4 block.

12. Push the slide room in by hand until the clamp strap

is flush with the side wall of the coach.

NOTE: Adjustment to the screw jack may be necessary to

assure the clamp strap is parallel to the sidewall of
the coach.

Fig. 22

#10 Pan Head Screws

13. Screw the clamp strap into the side wall by placing

a screw in the strap by each rack and in the middle
of the strap to ensure the rack is straight. Fill in
remaining screws (Fig. 22). Remove the screw jack.

14. From the inside of the coach, connect the wiring
harness to the motor cable.

15. Repeat this process for the other side of the slide
room.

16. Once you have completed both sides of the slide
room, synchronize the slide system motors (See
procedure below).

Synchronizing the Slide-Out Motors

1. Fully extend the slide room using the switch. Keep
the switch engaged until the motors shut down on
their own.

2. Retract the room 1-2 inches.

3. Repeat steps 1 and 2 until both motors shut down at

the same time. In many cases, two or three repetitions
are necessary to re-sync the system.

4. Fully extend and then retract the room. Again,
always let the motors shut down on their own before
releasing the switch.
