What You'll Need
Flathead screwdriver
Socket wrench
Crescent wrench
Door opener kit

A belt drive garage door opener is wonderful to have, especially if you live above or next to your garage. It is quiet and lasts a long time. This type of opener is similar to the chain driven model, but instead of the loud chain, it uses a rubber belt that runs more smoothly and quietly. The belt driven opener is a little more expensive to buy than the other models, but it is not difficult to build on your own.

Step 1 – Check the Garage Door

Before you install the garage door opener, make sure it works properly and is well-lubricated. If you are not able to raise it manually, check the springs, cables and pulleys and repair if necessary.

Step 2 – Prep the Door

If there are any ropes or cords already attached to the door, remove them before you move on. Remove any garage door locks as well. 

Step 3 – Set Up the Power

The power unit needs to be about 7 feet above the floor for safety reasons. The manual disconnect cable should be at least 6 feet from the garage floor or where all adults will be able to reach it in case of an emergency or power outage. If any permanent wiring is required, make sure the electricity is turned off in garage until wiring is complete. The garage door opener power cord needs to always be grounded to avoid shock.

Step 4 – Install the Buttons

A push button control comes with most belt drive garage door openers. This needs to be installed at least 5 or 6 feet from the floor of the garage so that adults can reach it, but not children.

Step 5 – Install the Header Bracket

Put the header bracket at the middle point of the door at the distance listed in the instruction manual. Then connect the idler assembly to the bracket of the power unit.

Step 6 - Mount the Power Unit

Mount the power unit in such a way that it will clear the door when it is open. It can be attached with mounting straps.

Step 7 – Attach the Linkage Assembly

To attach the linkage assembly, connect the door bracket to where it sits in the middle of the garage door. The manual should suggest a certain distance. The button control can now be attached in a location where it can be easily reached. Run the wires of the button control up the wall and along the ceiling over to the power unit to be attached. You can use staples to connect the wiring as long as you are cautious not to staple through the wire. To make sure your garage door operates correctly, properly position and adjust the eye system.
