Öhlins uses a piston band rather than metal-to-metal contact, which is what keeps the bore intact.\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 21045-02\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins publishes no separate dimension for this position, so the part number carries the identity. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. Öhlins uses a light spring so the valve reacts to shaft speed rather than to pressure alone.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Suspension is one of the few areas where the original part is genuinely the cheaper decision. 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\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21045-02 in this case. Öhlins does not publish a dimension here — go by the number and the exploded view. Piston bands are consumables — they wear against the bore and lose their seal gradually. Öhlins uses a light spring so the valve reacts to shaft speed rather than to pressure alone.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 21045-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check Valves\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":53649989271818,"sku":"21045-02","price":200.0,"currency_code":"MKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21045-02_09d77f23-2241-440a-9a54-662049f1d13e.png?v=1788876987","url":"https:\/\/inter-pace.com\/en-mk\/products\/ohlins-check-valve-shim-0-25-21045-02","provider":"Inter-Pace","version":"1.0","type":"link"}
