Part 235-948 is a replacement piston rod used in hydraulic systems on compatible PowrTwin, PowrTex, and PowrLiner equipment. This precision component transmits force from the hydraulic piston to the driven mechanism, enabling machine operation. When the original rod becomes worn, bent, or damaged, replacement restores proper power transmission.

The 235-948 piston rod is a direct replacement hydraulic component for a wide range of PowrTwin, PowrTex, and PowrLiner equipment including PowrTwin 12000 Plus DI service, 6900GH, 6900 XLT, 6900 XLT DI, 6900/12000 Plus DI, 4900GH, 4900 XLT, 4900/6900/8900/12000 Plus, 4500, 3500, and 3500 50th anniversary; PowrTex 6900SF/12000SV (including 0528919D); and PowrLiner 6950_1, 6950, 6900 XLT, 6900 XLT SP, 6000, 5000, 4950, 4900, 4900 XLT, 4000, and 4955/6955/8955. This precision-ground rod connects the hydraulic piston to the mechanism it drives, such as a pump or drive wheel. It transmits the linear force generated by hydraulic pressure, enabling machine functions. The rod operates under significant stress and must maintain a smooth surface to work effectively with seals. A worn, bent, or damaged rod can cause fluid leaks, loss of power, and erratic operation. This replacement rod is manufactured to exact specifications for length, diameter, surface finish, and end connections. Regular inspection helps identify rod wear before it leads to system failure.
| Force transmission | Transfers hydraulic force to driven mechanism |
|---|---|
| Motion transfer | Converts piston motion to linear movement |
| Seal interface | Provides smooth surface for rod seals |
| Worn / scored surface | Rod surface damaged, causing seal leaks |
|---|---|
| Bent rod | Rod deformation affects alignment |
| Corrosion damage | Rust or pitting compromises surface |
| Seal leakage | Fluid leaking past rod seals |
