Replacing the head as a unit is usually faster and more reliable than fitting the seals individually.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21754-01\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins publishes no separate dimension for this position, so the part number carries the identity. The bushing inside carries the side load so the seal only has to seal. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages. A seal head combines the oil seal, the dust seal and the shaft bushing in one serviceable assembly.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe part number is the contract: it defines material, dimension and finish together. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21754-01 in this case. This position has no published dimension, so the part number is the only reliable identifier. Head diameter and thread are specific to the tube it closes. Replacing seals at service intervals is far cheaper than replacing what a failed seal damages.\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 21754-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Seal Heads\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":53652826587402,"sku":"21754-01","price":238000.0,"currency_code":"CDF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21754-01_c1f1c425-9a18-402e-a1f5-41864e7fad57.png?v=1788880183","url":"https:\/\/inter-pace.com\/en-cd\/products\/ohlins-seal-head-38-5-21754-01","provider":"Inter-Pace","version":"1.0","type":"link"}
