ELECTRIC ACTUATOR INSPECTION,
REMOVAL AND REPLACEMENT
TSB Number: 11-004-21
Product: Electric Actuator
Date: June 21, 2021

LLabor Rate: 0.3 Hours Inspection/1.0 Hours Replacement

Purpose
Trailers must be inspected to determine if the units contain a 40" Venture High Speed Actuator with 18:1
Motor (part number 168956) and whether that actuator should be replaced. If the serial number identifies
the actuator as a model that must be replaced, procedures to remove and replace the actuator are included.

Safety
This document provides general instructions. 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 voiding the warranty, 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.
The "CAUTION" symbol above is a sign that a procedure has a safety risk involved and may cause
personal injury, product and/or property damage if not performed safely and within the parameters
set forth in this document.

Inspection
There is a two-step process for determining whether an actuator needs to be replaced. The actuator must be
identified as a Venture model, and then the serial number must also be included in a list of those models to
be replaced.

Identifying Venture Model

Removal and Replacement
The trailer must be supported per the manufacturer's recommendations before working
underneath. Failure to do so may result in death or serious injury.

Moving parts can pinch, crush or cut. Keep clear and use caution.
If the actuator is identified as needing replacement, procedures for the removal of the existing actuator and
installation of the replacement actuator are listed. There is also a video documenting these steps which can
be found at: https://support.lci1.com/videos/through-frame-slide-out-actuator-replacement
1.

Disconnect electric motor wires from the power source, including both power (red) and ground (black)
wires (Fig. 7).

Note: Failure to disconnect the actuator from the battery before manually operating the system can
cause damage to the system. Place wire nuts on the ends of the wires to prevent inadvertent power
connection.
Fig. 7

2.
3.

Move to the other end of the actuator shaft and measure from the bracket to the end of the threaded
rod (Fig. 8) and from the end of the stop can to the end of the threaded rod (Fig. 9).
Write down the two measurements.

Install manual crank onto the end of the actuator motor (Fig. 10).

Note: Some motors may not have a manual override extension on the end. If not equipped with extension,
use socket wrench on the hex head crank extension on the end of the shaft inside chassis main frame.
5.

Turn crank counterclockwise to extend the slide-out to provide enough clearance for removal of nylon
lock nut, jam nuts and the stop can.

Using an open-end wrench, loosen the nylon lock nut at the end of the threaded rod (Fig. 2) and then
remove the nut from the rod.
Manually retract the actuator by turning clockwise until the end of the threaded rod is pulled from the
bracket. Continue retracting actuator until there is adequate access to the remaining nuts and stop can.
Loosen and remove both remaining nuts (Figs. 11 and 12).
Lift actuator shaft and unscrew stop can from threaded rod (Fig. 13).

18. Reconnect motor wires to the power source using wire nuts.
19. Use zip ties to secure the wires to the motor and actuator.
20. Extend the slide-out so the threaded rod continues through the bracket until the middle nut is flush
with the bracket.
Note: A second person may be needed to assist lifting the shaft when extending the threaded rod
through the bracket.
21. Confirm the correct location of the middle jam nut based on the earlier measurement (Fig. 2). If
necessary, adjust location.
22. Loosen the interior nut and stop can and move them to the original location based on the earlier
measurement from the end of the threaded rod to the stop can (Fig. 3).
23. Using a wrench, tighten jam nut against stop can (Fig. 18).
24. Install remaining nylon lock nut on the end of the threaded rod.
