The Genie 36664R.S Shuttle Assembly for Screw Drive is a genuine OEM replacement traveler (also called the trolley or carriage) for select Genie screw-drive garage door openers. This component rides the screw drive rail and connects to the door arm to power the open and close cycle. A worn or broken shuttle can cause slipping, erratic travel, or a door that won’t move; replacing it restores smooth, reliable operation. The assembly incorporates the manual release mechanism so the door can be disengaged and operated by hand during a power outage or service.
Compatibility is limited to Genie screw-drive models that specifically call for part number 36664R.S; always confirm with your opener’s owner’s manual or parts diagram, or by checking the part label on your existing shuttle. Installation is typically straightforward for experienced DIYers: disconnect power, close the door, disengage the traveler, remove the old shuttle from the rail, slide the new shuttle onto the screw-drive rail, re-engage, then test and adjust travel/force settings per the manufacturer’s instructions. For safety, ensure the door is balanced and secured, and follow all Genie guidelines. This OEM Genie 36664R.S replacement is ideal for residential applications where maintaining original performance and compatibility is essential.
