The Marantec 91567 Sprocket Holder Assembly is a factory-identified replacement part designed to secure and align the drive sprocket within compatible Marantec garage door openers. By keeping the sprocket properly positioned, it helps maintain smooth chain engagement and consistent door travel, reducing noise and drift caused by a worn or damaged mount. This assembly is intended for select Marantec chain-drive systems and is referenced by the exact part number 91567 in Marantec parts diagrams, making it a reliable choice for owners and technicians seeking an OEM-matched repair part for residential garage door operator applications.
Installation typically involves disconnecting power, releasing the opener’s emergency pull, relieving chain tension, removing the opener cover, swapping the existing sprocket holder with the 91567 assembly, then re-tensioning the chain and verifying limits and force settings per the opener’s manual. For safety, service the opener only with the door in the down position, confirm proper photo-eye operation after reassembly, and perform a full open/close test cycle. Always verify compatibility by matching the part number 91567 to your Marantec model’s parts list or service documentation before ordering, as this sprocket holder assembly is not universal.
