Replacing an Old Gate and Centurion Gate Motor: A Step-by-Step Guide

Replacing an old gate (sliding gate installation) and installing a new Centurion gate motor can seem daunting. However, with a clear, step-by-step approach, the task becomes manageable. Today, I replaced my old, broken gate and motor. Here’s the process I followed.

Step 1: Attach Wheels to the Gate

The first step is to attach wheels to your gate. This allows the gate to move smoothly along the track.

Step 2: Install Photocells and Complete Wiring

Next, install the photocells and complete all necessary wiring. This ensures the gate operates safely and effectively.

Step 3: Position the Gate

Place the gate on the track. Roll it back and forth to mark the highest and lowest points on the post. Install the roller bracket, considering the length of the rollers and any attachments on the gate top, like a channel to keep the gate from roller marks.

Step 4: Install the Rollers

First, install the roller closest to the post. Ensure the gate is level in the closed position when attached to this roller. Then, install the second roller, maintaining a 2 mm distance between the gate and the second roller.

Step 5: Install the Catcher and Open Stopper

Install the catcher and open stopper next. This step is crucial. Without both stoppers, the gate could fall during motor installation.

Step 6: Attach the D6 Motor Plate

Before attaching the D6 motor plate, insert three bolts. This prepares the motor plate for secure attachment.

Step 7: Pour in the Oil

After installing the motor, pour in the oil. This ensures the motor operates smoothly and efficiently.

Step 8: Install the Rack

First, mark where the motor cog is in both closed and open positions. Then, assemble the rack from mark to mark. This helps you determine the best way to attach the rack, potentially saving time on cutting or adjusting its length. Avoid using square washers and textscrews that come with the rack.

Initially, screw the rack onto two screws for each piece. Then, reinforce around the joints. Finally, secure all remaining screws.

Step 9: Attach the Magnet with Tekscrews

Use tekscrews to attach the magnet. This method is easier and more efficient than using the original screws.


Replacing a gate and installing a new motor requires careful planning and precise execution. By following these steps, you can ensure a smooth, successful installation. Remember to take your time and double-check each step. This will guarantee your new gate operates safely and effectively.
