Repeated reciprocation of the accumulator piston causes wear at the piston pin bore interface. After this wear reaches a critical point, fluid loss through the piston pin bore cannot be compensated due to lack of pump volume. In addition, the piston can get cocked and gall the accumulator bore due to the pin bore wear or the spring bottoming out. To prevent these conditions in the 1-2 or 3-4 accumulator bores, Sonnax offers pinless accumulator piston kit 77998-03K.Pinless design eliminates the possibility of pin bore leakage and the additional length stabilizes the piston to prevent piston cockingDual seals stabilize and completely seal the bore and provide a tight seal even after thousands of cyclesSteel balls plug existing pin bore in case or coverContentsD-Ring VitonĀ®Pinless Accumulator Piston AluminumSeal PTFESteel Ball .312" dia.Steel Ball .236" dia.
