A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDimension A 6.3 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 05402-03\u003c\/li\u003e\n\u003cli\u003eDimension B 1.2 mm\u003c\/li\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFunction\u003c\/h2\u003e\u003cp\u003e6.3 mm, 1.2 mm: that is the whole specification, and it has to match what came out. Jets meter fixed bleed flow and are sized in tenths of a millimetre. Öhlins machines the ports rather than casting them, so the edges stay sharp and the flow predictable. The piston carries the shim stacks and meters the oil; its port layout is what makes an Öhlins damper behave the way it does.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eThe alternative to a service part is usually a new damper, which is why this catalogue exists. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins numbers do not follow a logic you can guess — always read them from the documentation. Service parts are ordered per piece unless stated otherwise.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e05402-03 is the Öhlins number for this position — the same one printed in the service documentation. The published dimensions are dimension a 6.3 mm, dimension b 1.2 mm — measure the old part against them if you are unsure. Port area and shim seat geometry decide the damping curve before any adjuster is touched. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eWe are an authorised Öhlins service centre, so you do not have to source the tools and the nitrogen: send us the damper and we rebuild it with the correct parts and the correct setting.\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 05402-03\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 1.2 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":53649780670730,"sku":"05402-03","price":101.0,"currency_code":"BBD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05402-03_e495ed01-cf51-4057-acf8-051f44a315bb.png?v=1788876576","url":"https:\/\/inter-pace.com\/en-bb\/products\/ohlins-check-valve-dia-6-3-1-2-05402-03","provider":"Inter-Pace","version":"1.0","type":"link"}
