Bushings in the fork carry the side load; play there shows up as knocking under braking. Öhlins publishes tube diameters by fork model, and they are not interchangeable across the range. Axle clamps are machined so the axle clamps without pinching the fork out of alignment.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. The alternative to a service part is usually a new damper, which is why this catalogue exists. The exploded drawing for your unit names the number; if you do not have it, we do. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21630-24 in this case. Check dimension a 43 mm, dimension b 50 mm, dimension c 55 mm against what you have removed; a close size is not the same part. A fork tube that has been bent is scrap: straightening changes the wall and it bends again. Cartridge tubes sit inside the fork leg and do the actual damping.\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 21630-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Fork Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 43 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 55 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":53650701779210,"sku":"21630-24","price":10208.0,"currency_code":"UAH","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21630-24_85a46971-11e7-4152-bf0f-950572b19e08.png?v=1788877340","url":"https:\/\/inter-pace.com\/en-ua\/products\/ohlins-fork-leg-outer-43-50-55-508-21630-24","provider":"Inter-Pace","version":"1.0","type":"link"}
