Öhlins builds the seat into the housing so the sealing face is machined, not pressed. Valves hold pressure in one direction and open in the other. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThis is an original Öhlins part, not an aftermarket equivalent — the tolerances are the ones the unit was assembled to. Öhlins numbers every position so a workshop can order precisely what it needs, not a whole assembly. Send us the model and serial number of your unit and we will confirm the position before you order. Order by part number — descriptions repeat across sizes, numbers do not.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 05566-05. Where several sizes share a description, only the number separates them. This position has no published dimension, so the part number is the only reliable identifier. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. A worn valve bleeds damping away without any visible symptom.\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 05566-05\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":53649965711626,"sku":"05566-05","price":75.18,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05566-05_20006d0c-9170-466f-b0bd-38588d508386.png?v=1788876859","url":"https:\/\/inter-pace.com\/en-gi\/products\/ohlins-valve-dia-1-6-shaft-bleed-4-0-05566-05","provider":"Inter-Pace","version":"1.0","type":"link"}
