A scored piston face means oil bypasses the shims entirely. Rebuilding a piston means keeping the shim order, because the stack is the tuning. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. Rebuilding to specification only works if the parts are to specification — that starts here. Where a number has been superseded, Öhlins states the replacement — we pass that on. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003e05666-20 is the Öhlins number for this position — the same one printed in the service documentation. This position has no published dimension, so the part number is the only reliable identifier. Valves hold pressure in one direction and open in the other. A worn piston band lets oil past the outside of the piston, which shows up as damping that has gone soft.\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 05666-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e 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":53650007097610,"sku":"05666-20","price":131.0,"currency_code":"QAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05666-20_3a2b32ca-4c2a-4f0a-bf49-5e4bb889e148.png?v=1788877000","url":"https:\/\/inter-pace.com\/en-qa\/products\/ohlins-valve-assy-dia-2-0-bleed-4-0-05666-20","provider":"Inter-Pace","version":"1.0","type":"link"}
