An adjuster that turns without resistance has lost its detent; the setting is then guesswork. Click adjusters work through a needle in a seat; the detent spring gives the clicks their feel. Its bores hold seals, so a scored housing leaks as surely as a shaft seal.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins publishes dimensions for its service parts so a workshop can verify before it fits. Suspension is one of the few areas where the original part is genuinely the cheaper decision. Service parts are ordered per piece unless stated otherwise. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21601-01 in the exploded view for the unit it belongs to. The thread is M46x1. The adjustment housing carries the needle, its seat and the detent mechanism. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003cp\u003eThe part is identical to what Öhlins fits in production — same supplier, same specification.\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 21601-01\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 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":53652578271498,"sku":"21601-01","price":107.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21601-01_6b5c97e9-4dfa-412e-b37c-04b431ac9bb2.png?v=1788879612","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-adjustment-housing-m46x1-21601-01","provider":"Inter-Pace","version":"1.0","type":"link"}
