Öhlins offers shafts in several lengths per diameter because the stroke differs by model. Any mark on the polished section is a reason to replace rather than to reassemble. This is a part that is replaced rather than repaired.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. We can supply the whole position from the drawing rather than the single piece if that is easier. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21637-07 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states diameter 12 mm, length 343 mm for this number, and those figures are the deciding ones. Corrosion on a stored damper usually starts on the exposed shaft. The polished section runs in the seal; a mark there ends the seal's life.\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 21637-07\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 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 343 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":53650780029194,"sku":"21637-07","price":69500.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21637-07_90fa9be0-878a-451b-9d37-91cafb1fe0df.png?v=1788877379","url":"https:\/\/inter-pace.com\/en-bf\/products\/ohlins-shaft-12-343-alu-21637-07","provider":"Inter-Pace","version":"1.0","type":"link"}
