Measure the old part against them before ordering. Öhlins builds click adjusters with defined detents so a setting can be written down and returned to. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit. A preload adjuster carries the full spring load and is built as a structural part.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Öhlins keeps service parts available for units long after they leave the current price list. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003e21933-01 is the Öhlins number for this position — the same one printed in the service documentation. Check dimension a 1 mm, dimension b 49 mm, dimension c 18 mm against what you have removed; a close size is not the same part. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics. An adjuster that turns without resistance has lost its detent; the setting is then guesswork.\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 21933-01\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 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 49 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension C:\u003c\/em\u003e 18 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":53653109637386,"sku":"21933-01","price":123000.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21933-01_1c08f22a-6c9b-4a43-9564-7d0e248594fd.png?v=1788880528","url":"https:\/\/inter-pace.com\/en-kr\/products\/ohlins-adjustment-housing-m46x1-49-18-21933-01","provider":"Inter-Pace","version":"1.0","type":"link"}
