Detent balls and springs are separate parts because they wear before the housing does. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Its length defines the preload range available on the unit.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e21632-04 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states dimension a 39 mm, dimension b 112 mm for this number, and those figures are the deciding ones. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range. A worn adjuster loses its clicks, and with them any chance of a methodical setup.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e 21632-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Preload Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 39 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 112 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCountry of Origin:\u003c\/em\u003e Sweden\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53652636958986,"sku":"21632-04","price":1000.0,"currency_code":"BDT","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21632-04_dd8eb803-7eab-4612-b481-53fa855f6cac.png?v=1788879780","url":"https:\/\/inter-pace.com\/en-bd\/products\/ohlins-preloadtube-polym-26-39-112-21632-04","provider":"Inter-Pace","version":"1.0","type":"link"}
