Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Order by part number. The dimensions below are the ones Öhlins publishes for it. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 21621-01 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. The thread is M40x1. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range.\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 21621-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Preload Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M40x1\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":53652604715274,"sku":"21621-01","price":490.56,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21621-01_e305a58b-b12c-449d-908a-10a3ba39af72.png?v=1788879663","url":"https:\/\/inter-pace.com\/en-cz\/products\/ohlins-preload-socket-m40x1-21621-01","provider":"Inter-Pace","version":"1.0","type":"link"}
