A tube that has been bottomed hard often shows a ring mark; that is a reason to replace it.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00890-51\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eLength 26 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eÖhlins publishes 46 mm, 26 mm for 00890-51 — the dimensions are the identity of the part. Surface finish is specified in microns, because it decides how quickly the piston band wears. 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\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Öhlins is one of the few suspension makers that still supplies every position in the exploded view as a single part. Where a number has been superseded, Öhlins states the replacement — we pass that on. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 00890-51 in this case. Check diameter 46 mm, length 26 mm against what you have removed; a close size is not the same part. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston. The tube carries the end cap threads, so damaged threads mean a new tube rather than a repair.\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 00890-51\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":53648963502346,"sku":"00890-51","price":1497.0,"currency_code":"QAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00890-51_b7ebb712-17f3-49fb-9ed5-c5a320d7ba3b.png?v=1788872809","url":"https:\/\/inter-pace.com\/en-qa\/products\/ohlins-cylinder-head-0-pb-46-26-00890-51","provider":"Inter-Pace","version":"1.0","type":"link"}
