An adjuster that turns without resistance has lost its detent; the setting is then guesswork. Detent balls and springs are separate parts because they wear before the housing does. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Rebuilding to specification only works if the parts are to specification — that starts here. 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\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e21653-16 is the Öhlins number for this position — the same one printed in the service documentation. Öhlins states dimension a 1.5 mm, dimension b 65.5 mm for this number, and those figures are the deciding ones. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. 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\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 21653-16\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 1.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 65.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M47x1.5\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":53652682014986,"sku":"21653-16","price":186600.0,"currency_code":"NGN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21653-16_13528ef9-6bc4-4b85-ac52-a570a860177d.png?v=1788879907","url":"https:\/\/inter-pace.com\/en-ng\/products\/ohlins-adjustment-housing-m47x1-5-65-5-21653-16","provider":"Inter-Pace","version":"1.0","type":"link"}
