Revalving means changing the stack, not the piston — that is why shims are sold singly. Öhlins stamps and grinds its shims to tolerances a general-purpose washer never holds. A shim is a thin steel washer, and a stack of them is what actually generates damping in an Öhlins unit — the oil has to bend them out of the way to pass.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\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 manufactures service parts on the same lines as production parts — there is no second quality. Send us the model and serial number of your unit and we will confirm the position before you order. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 00538-18 in this case. Öhlins states inner diameter 12 mm, outer diameter 18 mm, thickness 0.38 mm for this number, and those figures are the deciding ones. Outer diameter sets the lever the oil works against; thickness sets how hard it resists. Outer diameter sets the lever the oil works against, and thickness sets the resistance.\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 00538-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Shims\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 12 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 0.38 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":53647040184586,"sku":"00538-18","price":500.0,"currency_code":"GYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00538-18_8f4d37a4-e6ab-4d7f-86e0-28f373bde712.png?v=1788869610","url":"https:\/\/inter-pace.com\/en-gy\/products\/ohlins-shims-12-18-0-38-00538-18","provider":"Inter-Pace","version":"1.0","type":"link"}
