How to Replace V Belts on LiftMaster Operators - DDM Garage Doors Blog

Posted December 4th, 2020 at 6:39 pm by Dan Musick

In this video, we demonstrate how to replace V-Belts on LiftMaster operators.

There is a safe and easy way to replace operator V-Belts.

For safety, unplug the power to the operator and pry off the belt with a large screwdriver.

In this video, you’ll also find instructions for measuring the belt. For example, a 5/8″ wide belt that is 29.5″ long will be a 5L – the 5 for 5/8″ on the wider part of the belt, and then 5L295, the 295 is the length – 29.5 inches. In a tight spot, you can use a 5L290 or a 5L230 by adjusting the motor frame.

On our LiftMaster Commercial Operator Parts: Belts page, you can find the LiftMaster belts. All of the other residential and commercial V-Belts are on our Commercial Garage Door Opener V-Belts page.
