Thread size identifies where it belongs on the unit. A worn adjuster loses its clicks, and with them any chance of a methodical setup. Öhlins specifies a defined number of clicks per adjuster so a setting is a number, not an impression.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. The part is identical to what Öhlins fits in production — same supplier, same specification. Service parts are ordered per piece unless stated otherwise. We can supply the whole position from the drawing rather than the single piece if that is easier.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21653-01 in this case. The published dimensions are dimension a 1.5 mm, dimension b 18 mm — measure the old part against them if you are unsure. The adjustment housing carries the needle, its seat and the detent mechanism. A preload adjuster carries the full spring load and is built as a structural part.\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 21653-01\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 1.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 18 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":53650967036170,"sku":"21653-01","price":98.05,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21653-01_f0488397-3e0b-4a30-aab2-e1b2254e5bca.png?v=1788877465","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m47x1-5-18-21653-01","provider":"Inter-Pace","version":"1.0","type":"link"}
