Assemble Craftsman/Chamberlain Garage Door Opener

Assembly of a Craftsman Belt Drive garage door opener. Also Chamberlain Belt Drive openers have the same instructions. These openers have a piece together rail. The belt assembly has a tension spring that needs to be released to hold the belt tension over time. This unit has a battery back up. This video does not include installation of the unit.

Great video! I was having so much trouble with the trolley spring as well but this showed me what I was doing wrong.

Thanks, saved me an hour trying to figure out how to put together my belt that had loosened up and fell off!

Thank you, thank you, thank you! The installation manual was not clear on installing the trolley spring. I just followed along and it snapped right in.
