Its bores hold seals, so a scored housing leaks as surely as a shaft seal. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. Öhlins builds click adjusters with defined detents so a setting can be written down and returned to.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eA damper that can be rebuilt is a damper that stays on the bike; that is the whole argument for original service parts. An original part keeps the unit within its published specification; a near-equivalent quietly moves it. Order by part number. The dimensions below are the ones Öhlins publishes for it. If you are between two sizes, send us the measurement and we will check it against the catalogue.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 21976-10 in the exploded view for the unit it belongs to. Öhlins states dimension a 1 mm, dimension b 49.5 mm, dimension c 31 mm for this number, and those figures are the deciding ones. Compression and rebound adjusters are not interchangeable even when they look similar. Thread size identifies where it belongs on the unit.\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 21976-10\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 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 49.5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 31 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M46.5x1\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":53653159280906,"sku":"21976-10","price":3729.0,"currency_code":"THB","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21976-10_aa55a1f2-e5fe-4c7b-a66e-ce86974c97ff.png?v=1788880597","url":"https:\/\/inter-pace.com\/en-th\/products\/ohlins-adjustment-housing-m46-5x1-49-5-31-21976-10","provider":"Inter-Pace","version":"1.0","type":"link"}
