Yes, it’s usually a pretty straightforward swap if you can safely support the room and you have access to the motor location.
That said, on some installs it’s a 20-40 minute job, on others it turns into a pain because of access (underbelly, cabinetry, tight framing).
Below are some general removal/install steps you can follow.
Before you touch anything (critical)
-
Park level, wheels chocked.
-
Support the slide room. If you’re working on the drive side, don’t let the room drift or rack. If you have a helper, even better.
-
Kill power: disconnect shore power and disconnect the negative battery cable (or pull the slide/furnace style DC fuse feeding the slide). This motor can move with a bump of a switch.
Tools you’ll typically need
-
Socket set / ratchet (common: 3/8" drive, 7/16", 1/2", etc.)
-
Bit driver/screwdriver
-
Marker or tape (label wires)
-
Flashlight
-
Zip ties
Removal (typical Lippert through-frame with Tuson motor)
-
Get access to the motor/gearbox
-
Often behind an underbelly panel or a small service cover.
-
Motor is mounted to the slide cross-shaft/actuator assembly on the drive side.
-
-
Mark the wiring
-
These motors are two-wire (power and ground). Label them before removal.
-
-
Unplug/disconnect the motor wires
-
Sometimes it’s a 2-pin plug, sometimes butt connectors.
-
-
Remove the motor mounting bolts
-
Support the motor with one hand while removing the last bolt.
-
Pull the motor straight back off the drive interface.
-
-
Check the coupler/drive interface
-
Make sure the shaft/coupler isn’t stripped or cracked.
-
If the old motor failed due to binding, fix the binding or you’ll smoke the new motor too.
-
Installation
-
Match the new motor orientation
-
It should sit flush and square. Don’t force it at an angle.
-
-
Bolt it down
-
Snug evenly. Don’t overtighten into soft metal.
-
-
Reconnect wiring (same polarity as removed)
-
Two-wire hookup is typical; wrong polarity may reverse direction depending on controller setup.
-
-
Restore power
-
Reconnect battery negative.
-
-
Test extend/retract
-
Run the slide a few inches out and in.
-
Listen for binding or clicking.
-
If direction is backwards, swap polarity only if your system expects that (some controllers handle direction internally).
