Hydraulic preload adjusters are sealed units and are replaced rather than opened. Compression and rebound adjusters are not interchangeable even when they look similar. A worn adjuster loses its clicks, and with them any chance of a methodical setup.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. The part number is the contract: it defines material, dimension and finish together. Öhlins parts are unit-specific: a close dimension is not a substitute. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21820-03 is the Öhlins number for this position — the same one printed in the service documentation. This position has no published dimension, so the part number is the only reliable identifier. Öhlins builds click adjusters with defined detents so a setting can be written down and returned to. An adjuster that turns without resistance has lost its detent; the setting is then guesswork.\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 21820-03\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjusters\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":53652875280650,"sku":"21820-03","price":966000.0,"currency_code":"PYG","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21820-03_990c95c6-ac5d-4b66-829a-955693e4f71d.png?v=1788880302","url":"https:\/\/inter-pace.com\/en-py\/products\/ohlins-ec-adjuster-assy-sd-180-21820-03","provider":"Inter-Pace","version":"1.0","type":"link"}
