Shaft straightness matters: a bent shaft drags in the seal head and destroys the seal within hours. A bent shaft drags in the head and destroys the seal within hours — replace, never straighten. A shaft is threaded at both ends: one for the piston, one for the mounting.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. The alternative to a service part is usually a new damper, which is why this catalogue exists. Service parts are supplied per piece unless the description says otherwise. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21765-02 is the Öhlins number for this position — the same one printed in the service documentation. diameter 8 mm, length 381 mm is what distinguishes this number from its neighbours in the range. Corrosion on a stored damper usually starts on the exposed shaft. The damper shaft carries the piston through the oil and out through the seal head.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21765-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Damper Shafts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 381 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":53652850442506,"sku":"21765-02","price":44.34,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21765-02_ebde23a8-d59c-4912-977c-b599742a1776.png?v=1788880235","url":"https:\/\/inter-pace.com\/en-ca\/products\/ohlins-shaft-8-381-21765-02","provider":"Inter-Pace","version":"1.0","type":"link"}
