Lippert In-Wall Slide System
The information and instructions in a Keystone Service Bulletin (KSB) are intended to inform RV
dealership Service Managers/Technicians of situations that may occur with some Recreational
vehicles so dealership personnel can perform proper and efficient service. KSB’s are intended
to be used by trained RV technicians with the knowledge, tools and equipment to do the job
properly and safely, not “do-it-yourselfers”.

Information is not presented as a repair guaranteed to be covered by warranty.
Keystone’s P & P (Policy & Procedures) must be followed for any requested warranty
work.
Do not assume this repair is covered by warranty.
Not every unit listed requires a repair, only units exhibiting one or both sides that are
jammed up or inoperable require further action.

This process describes the repair of In-Wall slide systems that have become inoperable on
one or both sides. It has been determined the vehicles in this KSB population may have been
manufactured with an In-Wall Slide-Out System that may have a damaged guide shoe in the
slide mechanism.

REPLACEMENT OF THE INVERTED GEAR RACK
IN-WALL (SCHWINTEK) SLIDE-OUT SYSTEM
TSB Number: 146-001-2022C
Product: Inverted Gear Rack In-Wall Slide-Out System manufactured between October 2021 and January 2022
Date: August 7, 2024 Labor Rate: 3.4 Hours Allowed (1.7 hours per side)
Note: This bulletin supersedes service bulletin 146-001-2022 dated June 24, 2022, which should be
removed from your files. This revision provides information for replacing the Inverted In-Wall Slideout System as opposed to making repairs with a repair kit.
Note: This bulletin supersedes service bulletin 146-001-2022 dated June 22, 2022, which should be
removed from your files. This revision provides clarification around the repair kits and corrects an
error in kit "C" in the parts tables.

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 TI-177 IN-WALL® SLIDE-OUT TROUBLESHOOTING
AND COMPONENT REPLACEMENT document 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 MUST be addressed before proceeding with the
system replacement. If needed, contact Lippert Customer Care Center for further direction.
Note: Lippert does NOT require any advance notification or pre-authorization from the Customer
Care team if all required documentation is submitted with the request for reimbursement. If
the documentation is not submitted with the request, there could be a delay in processing the
claim for our dealer, repair center and OEM customers.

The necessary items for reimbursement processing include:
• Unit VIN.
• 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.

• Submission of completed form QR-085D.

Safety
The manuals 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.
