Measure the old part against them before ordering. A seal that has taken a set no longer springs back and starts to weep. Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. Size is given as inner diameter and cross-section; a close size is not a match.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins keeps service parts available for units long after they leave the current price list. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. The exploded drawing for your unit names the number; if you do not have it, we do. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eOrder under 00638-63. Where several sizes share a description, only the number separates them. Check inner diameter 84.0 mm, cross section 2.5 mm, material NBR 70 against what you have removed; a close size is not the same part. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. An O-ring seals by being squeezed into its groove; the cross-section is therefore as important as the diameter.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 00638-63\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e O-Rings\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 84.0 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 2.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMaterial:\u003c\/em\u003e NBR 70\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":53648924573962,"sku":"00638-63","price":8.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00638-63_e3e35ac1-de9f-40e4-946b-de04a2c4020f.png?v=1788872635","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-o-ring-84-0x2-5-nbr70-00638-63","provider":"Inter-Pace","version":"1.0","type":"link"}
