The Genie 33220A.S Sprocket Bushing is a genuine OEM replacement part designed for select Genie chain- and belt-drive garage door openers. Positioned at the drive sprocket in the motor head, this bushing supports and centers the sprocket on its shaft to maintain smooth rotation and proper chain or belt tracking. Replacing a worn bushing can help correct sprocket wobble, reduce vibration, and restore consistent drive performance, making it a common fix for noisy or uneven operation in residential Genie openers.
Intended for use only on models that specifically call out part number 33220A.S in their parts diagram, this factory component installs within the sprocket assembly. Typical service involves disconnecting power, relieving chain/belt tension, removing the sprocket retainer, swapping the bushing, then re-tensioning and checking travel limits and force settings per the opener’s manual. For safety, ensure the door is secured and the opener is unplugged before servicing; torsion/extension springs are under high tension and may require a qualified technician. Verify compatibility by referencing the opener’s model documentation or parts list for 33220A.S before ordering this Genie sprocket bushing replacement.
