Öhlins specifies the compound by position: NBR where oil is the concern, FKM where heat is. An oil seal that has hardened lets the shaft pass oil past it, and the damping fades long before the leak becomes visible. Seal heads combine the oil seal, the dust seal and the bushing in one assembly.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. Buying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Service parts are supplied per piece unless the description says otherwise. 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\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 00638-32 in the exploded view for the unit it belongs to. inner diameter 5.5 mm, cross section 1.5 mm, material NBR 70 is what distinguishes this number from its neighbours in the range. The dust seal does the hard work: it keeps the grit that would score the shaft away from the oil seal. Seal heads combine the oil seal, the dust seal and the bushing in one 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 00638-32\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 5.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCross Section:\u003c\/em\u003e 1.5 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":53648921297162,"sku":"00638-32","price":3.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00638-32_d78a573e-8051-485b-b632-11ad88b23f1a.png?v=1788872620","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-o-ring-5-5x1-5-nbr70-00638-32","provider":"Inter-Pace","version":"1.0","type":"link"}
