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. Two shims of the same thickness but different diameter give completely different damping. Öhlins stamps and grinds its shims to tolerances a general-purpose washer never holds.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. We can supply the whole position from the drawing rather than the single piece if that is easier. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 00520-25 in the exploded view for the unit it belongs to. The published dimensions are inner diameter 12 mm, outer diameter 25 mm, thickness 0.20 mm — measure the old part against them if you are unsure. A stack combines several diameters so the curve changes progressively rather than in steps. Öhlins grinds shims to a flatness tolerance because the faces have to seal against each other.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 00520-25\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 25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 0.20 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":53646913536266,"sku":"00520-25","price":96.0,"currency_code":"MUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00520-25_2184d7e1-57f0-4608-8426-1e54ed5ed1df.png?v=1788869503","url":"https:\/\/inter-pace.com\/en-mu\/products\/ohlins-shims-12-25-0-20-00520-25","provider":"Inter-Pace","version":"1.0","type":"link"}
