A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft. Valves and needles set the adjustable part of the damping; the piston sets the rest. Needle geometry sets the shape of the adjustable range, not just its size.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. A damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. Service parts are ordered per piece unless stated otherwise. Order by part number. The dimensions below are the ones Öhlins publishes for it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e15418-01 is the Öhlins number for this position — the same one printed in the service documentation. dimension a 38.6 mm, dimension b 37.4 mm, dimension c 5.2 mm is what distinguishes this number from its neighbours in the range. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 15418-01\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 38.6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 37.4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 5.2 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":53652325400842,"sku":"15418-01","price":14.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/15418-01_9205de30-f0de-4490-935e-bd4345867667.png?v=1788878739","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-check-valve-housing-38-6-37-4-5-2-15418-01","provider":"Inter-Pace","version":"1.0","type":"link"}
