The LiftMaster 41B4569 Pulley is a genuine OEM replacement part engineered for the drive system of select LiftMaster garage door openers. Serving as an idler that routes and supports the opener’s drive path, this pulley helps maintain proper alignment and tension of the chain or belt specified by the compatible model, promoting smooth door travel and reliable daily operation. It’s an ideal replacement part for restoring performance when the original pulley shows wear, wobble, or binding in residential garage door opener applications.
Use only on opener models that specifically list 41B4569 in the manufacturer’s parts diagram or service manual; verify compatibility by checking your opener’s model number and parts list before ordering. Installation typically involves disconnecting power to the opener, releasing the trolley, relieving chain or belt tension, transferring the drive to the new pulley, and re-tensioning before testing travel limits. For safety, disconnect power and secure the door in the down position before service. This LiftMaster 41B4569 Pulley supports dependable operation as a direct-fit, manufacturer-authorized replacement for compatible LiftMaster chain-drive or belt-drive systems.
