Detent balls and springs are separate parts because they wear before the housing does. Thread size identifies where it belongs on the unit. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Service parts are supplied per piece unless the description says otherwise. For a full rebuild, the seal kit plus the wear parts is usually the sensible order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21604-11 in this case. The thread is M47x1.5. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function. Compression and rebound adjusters are not interchangeable even when they look similar.\u003c\/p\u003e\u003cp\u003eÖhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs.\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 21604-11\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":53652581843210,"sku":"21604-11","price":60.77,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21604-11_6fb3bd96-3b2c-4d44-ac94-3b193383209b.png?v=1788879624","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m47x1-5-21604-11","provider":"Inter-Pace","version":"1.0","type":"link"}
