Measure the old part against them before ordering. Sealing washers are consumables — they take their shape on first assembly. Shoulder screws set a clearance as well as clamping, which is why the length is exact. Öhlins lists washers by thickness because it forms part of the internal stack height.\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. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e01149-01 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are dimension a 12 mm, dimension b 18 mm, dimension c 3.5 mm — measure the old part against them if you are unsure. A washer of the wrong thickness quietly changes preload on whatever it sits against. Sealing washers are consumables — they take their shape on first assembly.\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 01149-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 3.5 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":53649036050698,"sku":"01149-01","price":7.46,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01149-01_46ca9eec-4bc3-4a35-9c01-5d2e95162363.png?v=1788873339","url":"https:\/\/inter-pace.com\/products\/ohlins-wave-washer-12-18-3-5-01149-01","provider":"Inter-Pace","version":"1.0","type":"link"}
