It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eLength 31.5 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 03103-11\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003e03103-11 is the 46 mm, 31.5 mm version — Öhlins lists each size separately. Reservoir tubes carry the gas charge and are built to the same standard as the working cylinder. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable. Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Rebuilding to specification only works if the parts are to specification — that starts here. Service parts are ordered per piece unless stated otherwise. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 03103-11 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states diameter 46 mm, length 31.5 mm for this number, and those figures are the deciding ones. A scored bore means lost damping, because the oil bypasses the piston rather than being forced through the shims. A tube that has been bottomed hard often shows a ring mark; that is a reason to replace it.\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 03103-11\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 31.5 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":53648819880202,"sku":"03103-11","price":3519000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/03103-11_2373f717-8f76-4c20-8e1b-16d9b6f7f5e0.png?v=1788872019","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-cylinder-head-46-31-5-26-03103-11","provider":"Inter-Pace","version":"1.0","type":"link"}
