The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific. Tubes are replaced when the bore is marked; polishing them out changes the clearance and makes it worse.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. If the unit is already apart, compare the published dimensions with the part in your hand. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21070-15 in the exploded view for the unit it belongs to. Where no measurement is given, the drawing position is what identifies the part. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims. Tubes are replaced when the bore is marked; polishing them out changes the clearance and makes it worse.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21070-15\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":53652534526218,"sku":"21070-15","price":596.18,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21070-15_920bf07a-d158-40db-b3bd-cf6627a48f0f.png?v=1788879474","url":"https:\/\/inter-pace.com\/en-es\/products\/ohlins-cylinder-head-ttx36-21070-15","provider":"Inter-Pace","version":"1.0","type":"link"}
