Detent balls and springs are separate parts because they wear before the housing does. Thread size identifies where it belongs on the unit. Needle and seat together meter the bleed flow; damage to either changes the whole adjustment range.\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. The Öhlins exploded view names the number for each position; we can look it up if you do not have it. The exploded drawing for your unit names the number; if you do not have it, we do.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e21653-40 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. Compression and rebound adjusters are not interchangeable even when they look similar. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eA damper rebuild is workshop work: it needs the unit dismantled, the shim stack rebuilt in the correct order and the gas charge reset. We are an authorised Öhlins service centre and do exactly that in house — send us the unit or ask us to fit the part with your order.\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 21653-40\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":53651047809290,"sku":"21653-40","price":136.78,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21653-40_387e7dcf-12c6-4777-bd58-dba0da91f910.png?v=1788877504","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m47x1-5-65-5-21653-40","provider":"Inter-Pace","version":"1.0","type":"link"}
