Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimension B 1.0 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05402-02\u003c\/li\u003e\n\u003cli\u003eDimension A 6.3 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere It Sits\u003c\/h2\u003e\u003cp\u003eThe published figures are 6.3 mm, 1.0 mm. Measure the old part against them before ordering. A scored piston face means oil bypasses the shims entirely. Jets meter fixed bleed flow and are sized in tenths of a millimetre. Öhlins uses a light spring so the valve reacts to shaft speed rather than to pressure alone.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eSuspension is one of the few areas where the original part is genuinely the cheaper decision. This is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Order by part number — descriptions repeat across sizes, numbers do not. The exploded drawing for your unit names the number; if you do not have it, we do.\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 — 05402-02 in this case. Check dimension a 6.3 mm, dimension b 1.0 mm against what you have removed; a close size is not the same part. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable. If it sticks open, the damper loses low-speed damping entirely.\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 05402-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Check Valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 6.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 1.0 mm\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":53649165385994,"sku":"05402-02","price":13.94,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05402-02_3889d8c0-972f-4aac-bd63-38f48ddbef29.png?v=1788874064","url":"https:\/\/inter-pace.com\/en-jo\/products\/ohlins-check-valve-dia-6-3-1-0-05402-02","provider":"Inter-Pace","version":"1.0","type":"link"}
