The adjuster knob is what the rider touches, and Öhlins colour-codes it by function. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Öhlins builds click adjusters with defined detents so a setting can be written down and returned to.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Service parts are ordered per piece unless stated otherwise. Service parts are supplied per piece unless the description says otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21945-01 in the exploded view for the unit it belongs to. Öhlins states dimension a 1 mm, dimension b 46.5 mm, dimension c 18 mm for this number, and those figures are the deciding ones. Hydraulic preload adjusters are sealed units and are replaced rather than opened. Preload adjusters carry the full spring force and are built accordingly.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 21945-01\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 46.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 18 mm\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":53653146697994,"sku":"21945-01","price":1848000.0,"currency_code":"VND","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21945-01_920021b4-129b-4a3b-877e-df1580a1803f.png?v=1788880561","url":"https:\/\/inter-pace.com\/en-vn\/products\/ohlins-adjustment-housing-m40x1-46-5-18-21945-01","provider":"Inter-Pace","version":"1.0","type":"link"}
