Bushings in the fork carry the side load; play there shows up as knocking under braking. Diameter and length identify the tube; both follow the fork model. Cartridge tubes sit inside the fork leg and do the actual damping.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Where a number has been superseded, Öhlins states the replacement — we pass that on. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 04761-29 in the exploded view for the unit it belongs to. The published dimensions are dimension a 48 mm, dimension b 639 mm — measure the old part against them if you are unsure. Inner tubes carry a low-friction coating; once it is through, the seals wear quickly. A marked inner tube destroys seals repeatedly until it is replaced.\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 04761-29\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Inner Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 48 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 639 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":53649026973962,"sku":"04761-29","price":25900.0,"currency_code":"DZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04761-29_66fc1659-1723-4184-bff7-15ff7f37e03c.png?v=1788873237","url":"https:\/\/inter-pace.com\/en-dz\/products\/ohlins-inner-tube-48-639-04761-29","provider":"Inter-Pace","version":"1.0","type":"link"}
