The LiftMaster 41B5348-2 Sprocket & Sprocket Cover w/ Screws is a genuine OEM replacement assembly for select LiftMaster and Chamberlain chain-drive garage door openers. This part replaces the drive sprocket at the top of the operator head—the component that engages the chain to transfer motor power to the rail—along with its protective cover and the required mounting screws. Use it to restore smooth, dependable door travel when the original sprocket is worn, chipped, or noisy, or when the cover is damaged and no longer shields the drive from dust and debris. It’s intended for residential chain-drive systems that specifically call for part number 41B5348-2; always confirm compatibility in your opener’s parts list or service manual.
Installation typically involves unplugging the opener, disengaging the trolley, relieving chain tension, removing the old sprocket and cover, and fitting the new assembly before re-tensioning the chain and verifying travel limits. After replacement, test door balance and perform safety checks including force reversal and photo eye operation. No electrical programming changes are normally required unless limits are disturbed during service. For safe results, service the opener with power disconnected and the door secured, or consult a qualified technician. This OEM LiftMaster sprocket and cover set is an ideal replacement part for chain-drive garage door opener repair and maintenance, helping reduce chain slip and vibration while protecting the drive components.
