Adjuster housings carry seals, and a leak there empties the damper as surely as a shaft seal.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 21052-02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThis position is identified by its number rather than by a dimension. Preload adjusters carry the full spring force and are built accordingly. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function. Electronically controlled adjusters replace the needle with a solenoid but keep the same hydraulics.\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. Öhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. Tell us the damper's model designation and year and we will match the number for you. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 21052-02 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. This position has no published dimension, so the part number is the only reliable identifier. Hydraulic preload adjusters are sealed units and are replaced rather than opened. 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\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 21052-02\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":53650037276938,"sku":"21052-02","price":25.72,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21052-02_736ce748-7087-4ef3-b3ad-42b4d1dc5bf8.png?v=1788877016","url":"https:\/\/inter-pace.com\/products\/ohlins-adjuster-knob-al-21052-02","provider":"Inter-Pace","version":"1.0","type":"link"}
