Port area and shim seat geometry decide the damping curve before any adjuster is touched. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. Send us the model and serial number of your unit and we will confirm the position before you order. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003ePart number 05402-06 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states dimension a 6.3 mm, dimension b 1.8 mm for this number, and those figures are the deciding ones. Needle geometry sets the shape of the adjustable range, not just its size. Piston bands are consumables — they wear against the bore and lose their seal gradually.\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 05402-06\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check Valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 1.8 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":53649165811978,"sku":"05402-06","price":9.79,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05402-06_77e64e9c-5b01-4e1b-b151-47a68512e947.png?v=1788874069","url":"https:\/\/inter-pace.com\/products\/ohlins-check-valve-dia-6-3-1-8-05402-06","provider":"Inter-Pace","version":"1.0","type":"link"}
