Part 2336971 is a replacement pressure vessel used in the hydraulic system of compatible Elite and PowrLiner line stripers. This sealed component stores hydraulic fluid under pressure, providing stored energy for smooth drive operation and consistent performance. When the original vessel loses its pre-charge or develops leaks, replacement restores proper hydraulic system function.

The 2336971 pressure vessel is a direct replacement hydraulic component for Elite 3500, PowrLiner 3000, 3500s, and PowrLiner 3500 72v line stripers. This sealed accumulator stores hydraulic fluid under pressure using a pre-charged gas bladder or diaphragm. It serves as an energy reservoir, smoothing pressure fluctuations from the hydraulic pump and providing immediate flow for drive functions. A properly functioning pressure vessel ensures smooth acceleration, consistent striping speed, and responsive drive control. When the vessel loses its gas pre-charge or develops an internal leak, symptoms include jerky movement, slow response, or loss of drive power. This replacement vessel is manufactured to match original specifications for capacity and pre-charge pressure. Installation requires proper bleeding of the hydraulic system to remove air.
| Energy storage | Stores hydraulic fluid under pressure for immediate use |
|---|---|
| Pressure smoothing | Dampens pump pulsations for smooth operation |
| Drive response | Provides rapid fluid flow for acceleration |
| Lost pre-charge | Gas charge depleted, no energy storage |
|---|---|
| Internal leakage | Bladder/diaphragm failed, fluid on gas side |
| External leaks | Hydraulic fluid leaking from vessel |
| Erratic drive | Jerky movement or slow response |
