It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps. Tubes are replaced when the bore is marked; polishing them out changes the clearance and makes it worse. The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. The alternative to a service part is usually a new damper, which is why this catalogue exists. Order by part number — descriptions repeat across sizes, numbers do not. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e00870-70 is the Öhlins number for this position — the same one printed in the service documentation. Check diameter 46 mm, length 26 mm against what you have removed; a close size is not the same part. It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps. Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 00870-70\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 26 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":53648959963402,"sku":"00870-70","price":800000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00870-70_3ca7ee67-4fc2-4b5b-a1f9-578099efa9c8.png?v=1788872786","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-cylinder-head-90-pb-46-26-00870-70","provider":"Inter-Pace","version":"1.0","type":"link"}
