LiftMaster 041B5348 Sprocket and Hub Kit
The LiftMaster 041B5348 sprocket and hub kit is a chain drive service part used to restore the point where the opener chain is guided and driven through the rail system. A worn sprocket or hub can create chain chatter, skipping, metal or plastic shavings, rough trolley movement, or chain misalignment. Replacing the correct sprocket and hub helps the chain stay centered and reduces extra wear on the chain, rail, and internal drive components.
This kit is used with select LiftMaster and Chamberlain chain drive garage door openers that call for 041B5348, 41B5348, or 062124 in the replacement parts breakdown. Since similar sprocket kits exist for different opener generations and rail designs, do not choose this part by appearance alone. If the opener has heavy grinding, failure to move the door, or a stripped gear condition, inspect the internal gear and sprocket assembly as well before deciding which service kit is needed.
