Part 143-822 is a replacement cylinder for compatible PowrTwin and PowrLiner equipment. This precision component houses the piston in hydraulic or fluid systems, providing the chamber where pressure is generated. When the original cylinder becomes worn, scored, or damaged, replacement restores proper system function.

The 143-822 cylinder is a direct replacement component for PowrTwin 6900GH, 6900 XLT, 4900/6900/8900/12000 Plus, and various PowrLiner models including 6950_1, 6950, 6900 XLT, 6900 XLT SP, 6000, 4950, and 4955/6955/8955 equipment. This precision-machined cylinder is a critical component in hydraulic or fluid power systems, providing the chamber in which a piston reciprocates. The cylinder's inner bore is finished to precise tolerances and surface finish to work effectively with the piston and seals, creating a pressure-tight chamber that converts fluid pressure into linear force. A properly functioning cylinder is essential for achieving rated force, maintaining smooth motion, and ensuring efficient operation. A worn, scored, or corroded cylinder can cause loss of pressure, leakage past the piston, erratic motion, and accelerated seal wear. This replacement cylinder is manufactured to exact specifications for bore size, length, and mounting features. The material is selected for durability and compatibility with hydraulic fluids. Installation requires careful cleaning and proper alignment with the piston and seals. Regular inspection during system overhaul helps identify cylinder wear before it leads to significant performance loss.
| Piston housing | Contains piston during operation |
|---|---|
| Pressure chamber | Fluid is pressurized within cylinder |
| Sealing surface | Provides surface for piston seals |
| Worn / scored bore | Inner surface damaged, causing leaks |
|---|---|
| Loss of pressure | System cannot maintain set pressure |
| Excessive wear | Seals wear rapidly due to rough bore |
| Corrosion damage | Pitting or rust compromises surface |
