The LiftMaster K10-10166 Clutch Plate is a genuine OEM replacement component for select LiftMaster commercial door operators that use an adjustable friction clutch. Positioned within the clutch stack, this plate helps transfer drive torque while slipping under overload to protect the operator, gearbox, and door system from damage. Replacing a worn or glazed clutch plate restores consistent torque transmission, reduces nuisance slippage, and maintains reliable operation in demanding commercial and industrial applications.
Use this replacement part when servicing the clutch assembly on compatible LiftMaster commercial door operators such as jackshaft, hoist, and trolley styles. For correct fit and setup, verify compatibility against the operator’s parts diagram or service manual by part number K10-10166. Installation involves disassembling the clutch assembly and re-setting the clutch adjustment to the manufacturer’s specification; it should be performed by a qualified technician using lockout/tagout procedures. After installation, test door travel and all entrapment protection devices per UL 325 guidelines to confirm safe operation.
