The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair. The cylinder head closes the working bore and carries the shaft seal and its bushing. Tubes are replaced when the bore is marked; polishing them out changes the clearance and makes it worse.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Rebuilding to specification only works if the parts are to specification — that starts here. For a full rebuild, the seal kit plus the wear parts is usually the sensible order. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 04882-31. Öhlins states diameter 46 mm, length 26 mm for this number, and those figures are the deciding ones. A head that has been over-tightened distorts and stops sealing. Öhlins hones its tubes to a defined surface finish rather than simply to a diameter.\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 04882-31\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":53649655169290,"sku":"04882-31","price":370.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04882-31_1c4ce296-2893-4c54-b657-15857f168b9a.png?v=1788876153","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-head-153deg-pb-46-26-04882-31","provider":"Inter-Pace","version":"1.0","type":"link"}
