Part 0528164A is a replacement down tube for compatible PowrLiner and PowrTwin equipment. This vertical tube connects upper and lower sections of the equipment frame or handle, providing structural support and routing for cables or hoses. When the original tube becomes bent, cracked, or corroded, replacement restores structural integrity.

The 0528164A down tube is a direct replacement structural component for PowrLiner 4955, 6955, 8955 and multiple PowrTwin models including 4900, 6900, 8900, 12000 Plus, 6900, 12000 Plus DI, and 12000 Plus DI service equipment. This vertical tube is a critical part of the equipment's frame or handle assembly, connecting upper sections (such as the handle or control panel) to the lower chassis or base. It provides essential structural support, maintaining the rigidity and alignment of the machine. The down tube may also serve as a conduit for routing cables, hoses, or control linkages between upper and lower sections, protecting them from damage. A bent, cracked, or corroded down tube can compromise equipment stability, cause misalignment of controls, and create safety hazards. This replacement tube is manufactured to exact specifications for length, diameter, mounting hole locations, and any integrated features. Installation may require transferring brackets or hardware from the original tube. Regular inspection helps identify tube damage before it affects equipment safety or function.
