A worn stop-mast assembly can cause uncontrolled mast movement during operation. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1055866. The stop-mast assembly functions as a mechanical limit device that arrests the mast's travel at its designed endpoint. A common failure consequence is the mast over-traveling, which may damage the carriage or chain system. During routine service, a technician might notice the mast failing to stop at its normal height limit. The item ships at approximately 1.142 pounds.
