Any mark on the polished section is a reason to replace rather than to reassemble. Shafts are not shortened or extended; the length is the specification. The damper shaft carries the piston and passes through the seal head, so its surface finish decides how long the seals last.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003ePart number 21000-66 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Check diameter 14 mm, length 157 mm against what you have removed; a close size is not the same part. The polished section runs in the seal; a mark there ends the seal's life. The shaft is threaded at both ends: piston at one, mounting at the other.\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 21000-66\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 14 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 157 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":53649902207242,"sku":"21000-66","price":29.23,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21000-66_abd40a5c-edef-4e93-90cd-46664c47b7b4.png?v=1788876759","url":"https:\/\/inter-pace.com\/en-gb\/products\/ohlins-shaft-14-157-21000-66","provider":"Inter-Pace","version":"1.0","type":"link"}
