The needle tip is the wear part: once rounded, the first few clicks stop doing anything.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eÖhlins part number 21150-02\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal. Detent balls and springs are separate parts because they wear before the housing does. Hydraulic preload adjusters are sealed and pressurised; they are replaced as a unit.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Order by part number. The dimensions below are the ones Öhlins publishes for it. Öhlins parts are unit-specific: a close dimension is not a substitute.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eIf the unit is already open, compare the dimensions below with the part in your hand before ordering 21150-02. This position has no published dimension, so the part number is the only reliable identifier. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics. Detent balls and springs are separate parts because they wear before the housing does.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21150-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Adjusters\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":53652546322698,"sku":"21150-02","price":439.17,"currency_code":"SEK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21150-02_f426302e-2949-45c7-a080-8190263e8b11.png?v=1788879516","url":"https:\/\/inter-pace.com\/en-se\/products\/ohlins-knob-compression-adjuster-21150-02","provider":"Inter-Pace","version":"1.0","type":"link"}
