This sprocket appears in LiftMaster’s MAXUM JDC and JHDC component selection guide. Compatibility depends on the complete operator and door configuration; matching shaft diameter alone is insufficient. Verify the required tooth count, chain size, keyway, and installation clearance before ordering.
During replacement, have a qualified door technician inspect the chain and mating sprocket for wear and confirm proper alignment. Disconnect and lock out operator power before servicing, and follow the operator’s installation instructions.
Order this 60-tooth sprocket when your approved LiftMaster setup calls for #50 chain, a 1-1/4" bore, and a 1/4" keyway.
