A preload adjuster carries the full spring load and is built as a structural part. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. Compression and rebound adjusters are not interchangeable even when they look similar.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eEvery part in this catalogue is one Öhlins fits itself during assembly and service. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21907-04. dimension a 1 mm, dimension b 18 mm is what distinguishes this number from its neighbours in the range. Öhlins publishes the click count for each unit, and a rebuilt adjuster should return it. Click adjusters work through a needle in a seat; the detent spring gives the clicks their feel.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 21907-04\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjustment Housings\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M46x1\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":53652970602762,"sku":"21907-04","price":36.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21907-04_ad52098b-53e0-4342-9d40-0c5e17b4d0ca.png?v=1788880441","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m46x1-18-21907-04","provider":"Inter-Pace","version":"1.0","type":"link"}
