STOP-MAST ASSY (CAT CT1055866)

A worn stop-mast assembly can cause uncontrolled mast movement during operation. This aftermarket replacement part references CAT as the OE maker and cross-references part number CT1055866. The stop-mast assembly functions as a mechanical limit component that arrests vertical travel of the mast structure. A common failure consequence is the mast over-traveling, which may lead to load instability or structural binding. Keeping this assembly in sound condition helps maintain predictable mast positioning during routine cycles. The item ships at approximately 1.142 pounds. Verify the serial number or application, then call (562) 693-7748.
