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.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePinless design eliminates the possibility of pin bore leakage and the additional length stabilizes the piston to prevent piston cocking\u003c\/li\u003e\n\u003cli\u003eDual seals stabilize and completely seal the bore and provide a tight seal even after thousands of cycles\u003c\/li\u003e\n\u003cli\u003eSteel balls plug existing pin bore in case or cover\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"part-accordion cb spaced-vertical\"\u003e\n\u003cdiv id=\"components\"\u003e\n\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents\u003c\/label\u003e\u003c\/strong\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eD-Ring \u003ci\u003eViton®\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003ePinless Accumulator Piston \u003ci\u003eAluminum\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003eSeal \u003ci\u003ePTFE\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003eSteel Ball \u003ci\u003e.312\" dia.\u003c\/i\u003e\n\u003c\/li\u003e\n\u003cli\u003eSteel Ball \u003ci\u003e.236\" dia.\u003c\/i\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"specs\"\u003e\n\u003cstrong\u003e\u003clabel for=\"specs-panel\"\u003eSpecs\u003c\/label\u003e\u003c\/strong\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":48137418080478,"sku":"S74927K","price":16.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/S74927K_1.jpg?v=1776800966","url":"https:\/\/transmissioncenter.net\/products\/4l60e-performance-pinless-accumulator-piston-kit-1-2-3-4-sonnax-77998-03k","provider":"Transmission Center","version":"1.0","type":"link"}
