Seal kits gather the pieces one rebuild needs, which avoids a second order mid-job. Head diameter and thread are specific to the tube it closes. Öhlins specifies seal compounds for temperature stability rather than for the lowest unit cost.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Rebuilding to specification only works if the parts are to specification — that starts here. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e21922-01 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states inner diameter 10 mm, outer diameter 31 mm, thickness 40 mm for this number, and those figures are the deciding ones. Öhlins builds the head so the dust seal takes the grit before it reaches 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\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 21922-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eInner Diameter:\u003c\/em\u003e 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eOuter Diameter:\u003c\/em\u003e 31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThickness:\u003c\/em\u003e 40 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":53652074561802,"sku":"21922-01","price":30.61,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21922-01_d4d3a369-b689-4bb5-b288-d5dca30d148d.png?v=1788878044","url":"https:\/\/inter-pace.com\/en-na\/products\/ohlins-cap-seal-head-10-31-40-21922-01","provider":"Inter-Pace","version":"1.0","type":"link"}
