The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair. Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against. The cylinder tube is the working bore of the damper: the piston runs in it, and its finish decides how well the piston rings seal.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. Öhlins keeps service parts available for units long after they leave the current price list. If you are between two sizes, send us the measurement and we will check it against the catalogue. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21873-01. Where no measurement is given, the drawing position is what identifies the part. Twin-tube dampers use two concentric tubes, and both are listed separately. 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\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 21873-01\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":53652900053258,"sku":"21873-01","price":910000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21873-01_f2657c13-ce0d-4662-a488-4c2001864986.png?v=1788880378","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-cylinder-head-ttx36-21873-01","provider":"Inter-Pace","version":"1.0","type":"link"}
