The LiftMaster CA200-60 Crown Sub-Assembly is an OEM replacement drive component engineered for LiftMaster operator models LM1600 and LM2000. Designed to restore smooth, reliable motion in the operator’s drivetrain, this crown sub-assembly replaces a worn or damaged crown assembly within the gear reduction system, helping eliminate grinding, slippage, or irregular travel. As a genuine Chamberlain LiftMaster part, CA200-60 matches factory specifications for the LM1600/LM2000 platform and is intended for use in maintaining installed units to original performance. It is not a universal substitute; confirm compatibility by verifying the operator model and revision before ordering.
Installation involves internal mechanical service of the operator and should be performed by a qualified technician following the LiftMaster LM1600/LM2000 service documentation. Disconnect power before servicing, align the gear train correctly, secure fasteners to the specified torque, and apply lubrication only as recommended by LiftMaster. After reassembly, test travel limits, entrapment protections, and any connected safety devices to ensure proper operation. No controller programming changes are typically required for this mechanical replacement, but functional testing and limit verification are essential. For accurate identification and procedures, refer to the official LiftMaster parts list and service manual for the LM1600 and LM2000.
