The LiftMaster 41C588 Drive Shaft Cover is a genuine OEM garage door opener replacement part designed to enclose and protect the rotating drive shaft area on compatible LiftMaster operators. By shielding the shaft and related components from dust and accidental contact, this cover helps maintain smooth, reliable operation and supports safe use. It is intended as a direct replacement for a damaged or missing cover on units that specifically list 41C588 in their parts diagram or service documentation.
Installation is straightforward for most do-it-yourselfers and technicians: disconnect power to the opener, remove the existing cover (if present), position the new cover over the drive shaft section of the motor head, and secure it using the factory hardware. No adjustments or programming are required after installation. Because compatibility is model-specific, confirm that your LiftMaster or Chamberlain garage door opener manual calls out part 41C588 before ordering. This OEM drive shaft guard is commonly used on select residential chain-drive trolley openers; refer to your unit’s parts list for exact fitment. Always follow manufacturer safety guidelines when servicing any garage door operator.
