Aluminium tubes are hard-anodised in the bore so the piston band has a hard surface to run against.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eLength 26 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00890-56\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003e00890-56 is the 46 mm, 26 mm version — Öhlins lists each size separately. A head that has been over-tightened distorts and stops sealing. 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\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Öhlins publishes dimensions for its service parts so a workshop can verify before it fits. We can supply the whole position from the drawing rather than the single piece if that is easier. If the unit is already apart, compare the published dimensions with the part in your hand.\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 00890-56. Check diameter 46 mm, length 26 mm against what you have removed; a close size is not the same part. The cylinder head closes the working bore and carries the shaft seal and its bushing. Most seal kits are built around a specific head design.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 00890-56\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":53648964256010,"sku":"00890-56","price":510200.0,"currency_code":"RWF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00890-56_e49ae8fe-9ac2-4ebb-9c8a-8d61a2cfeb61.png?v=1788872812","url":"https:\/\/inter-pace.com\/en-rw\/products\/ohlins-cylinder-head-90-pb-46-26-00890-56","provider":"Inter-Pace","version":"1.0","type":"link"}
