REPAIR OF THE INVERTED GEAR RACK
IN-WALL (SCHWINTEK) SLIDE-OUT SYSTEM
TSB Number: 146-001-2022
Product: Inverted Gear Rack In-Wall Slide-Out System manufactured between October 2021 and January 2022
Date: June 22, 2022

LLabor Rate: 5.0 Hours Allowed (2.5 hours per side)

Purpose
This document is to address the concern of the increased frequency of Schwintek slide systems becoming
inoperable in the identified time frame.
The primary cause has been determined to be damage to the guide shoe located within the slide
mechanism. This can lead to premature system wear and in some cases reaching the point of rendering the
system inoperable. While there are multiple contributing factors that can cause this to happen, we have
identified a period between October 2021 and January 2022 when inconsistent handling at the Lippert
production facility may have caused damage to some shoes. In addition to implementing corrective actions
during the assembly process, Lippert made a design improvement to the shoe to provide additional
strength. Systems that were subject to damage during this time may be more prone to breakage under
certain conditions.
It is important to review the attached In-Wall Slide-Out Repair Kit Manual and conduct an inspection of the
system to determine the exact cause of the concern. Any obstructions in the system, any damage to wiper
seals, any system measurements as referenced that fall out of specification need to be addressed before
proceeding with the TSB repair kit. If needed, contact Lippert Customer Care Center for further direction.

Note: Lippert does NOT require advance notification nor a pre-authorization be obtained from
our team. With the proper documents submitted with all requests for reimbursement from
dealers, repair centers or OEMs, Lippert will be able to waive any advance contact to the
Customer Care Center and process the claim with no delay.

The necessary items for reimbursement processing include:
• Clear photo of the unit VIN tag
• Clear photo of the Lippert In-Wall system tag (See location of tag on Page 3.)
The tag shown below is only a sample picture and not the actual tag for an inverted gear
rack slide-out.

• Eight photos of the system after completing the repair (See example on Page 2.)

Photos of Measurements After Completing Repair

2.

Take measurements (similar to the measurement featured below) from the gear rack to the edge of the
column with the tape measure pressed against the gear rack, not above or below it.
This measurement is best taken with the slide extended at 6 inches from the exterior of the coach and
then again with the slide at full extension at all four corners for a total of eight measurements.

Note: Coachmen is an exception since the units are installed backward and measurements should be
taken from the interior.

Tolerance is 2 3/8" to 2 5/8". Ideal measurement is 2 1/2".

Safety
The In-Wall Slide-Out Repair Kit Manual referenced and attached to this TSB are general instructions for the
various In-Wall systems. Many variables can change the circumstances of any procedure, i.e. the degree of
difficulty involved in the service operation and the ability level of the individual performing the operation.
This document cannot begin to plot out procedures for every possibility, but will provide the general
instructions for effectively installing, removing or servicing the system. In the event the skill level required
is too advanced or the procedure too difficult, a certified technician should be consulted before performing
the necessary operation. Failure to correctly install, remove or service the system may result in inflicting
injury or even death.
The "WARNING" symbol above is a sign that a procedure has a safety risk involved and may cause
death, serious personal injury, severe product and/or property damage if not performed safely and
within the parameters set forth in this document.
