Thread size identifies where it belongs on the unit. 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\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Parts remain available years after a unit leaves the current price list, which is unusual in this trade. We can supply the whole position from the drawing rather than the single piece if that is easier. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson.\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 — 21653-44 in this case. The published dimensions are dimension a 1 mm, dimension b 55 mm — measure the old part against them if you are unsure. Its bores hold seals, so a scored housing leaks as surely as a shaft seal. Hydraulic preload adjusters are sealed units and are replaced rather than opened.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eAsk us about a full service: as an authorised Öhlins centre we strip, inspect, replace what is worn and set the unit back to its specification.\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 21653-44\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 55 mm\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":53652693549322,"sku":"21653-44","price":107.24,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21653-44_6482e3b7-db43-4f0d-9248-fe7c421878dd.png?v=1788879933","url":"https:\/\/inter-pace.com\/products\/ohlins-adjustment-housing-m46x1-55-21653-44","provider":"Inter-Pace","version":"1.0","type":"link"}
