An adjuster that turns without resistance has lost its detent; the setting is then guesswork. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Thread size identifies where it belongs on the unit.\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. Öhlins manufactures service parts on the same lines as production parts — there is no second quality. We can check the number against the Öhlins exploded view before you order — just ask. Öhlins numbers do not follow a logic you can guess — always read them from the documentation.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e21604-06 is the Öhlins number for this position — the same one printed in the service documentation. The thread is M47x1.5. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range. The adjustment housing carries the needle, its seat and the detent mechanism.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21604-06\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjustment Housings\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":53652580303114,"sku":"21604-06","price":90.69,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21604-06_6c93ce41-dc52-4431-b568-04c95ece466e.png?v=1788879619","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m47x1-5-21604-06","provider":"Inter-Pace","version":"1.0","type":"link"}
