Öhlins hones its tubes to a defined surface finish rather than simply to a diameter.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21877-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThere is no measurement to check here — the number and the exploded view identify it. Corrosion inside a tube is terminal: it cannot be honed out without changing the clearance. It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eAn original part keeps the unit within its published specification; a near-equivalent quietly moves it. The part number is the contract: it defines material, dimension and finish together. We can check the number against the Öhlins exploded view before you order — just ask. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21877-01 in the exploded view for the unit it belongs to. This position has no published dimension, so the part number is the only reliable identifier. The tube is what the whole damper is built around: everything else references its bore. It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps.\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 21877-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\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":53652902904074,"sku":"21877-01","price":463000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21877-01_3dab00db-a1f7-4908-84bb-7448a897d034.png?v=1788880387","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-cylinder-head-ttx36-21877-01","provider":"Inter-Pace","version":"1.0","type":"link"}
