Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. 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\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eÖhlins manufactures service parts on the same lines as production parts — there is no second quality. The tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. We can supply the whole position from the drawing rather than the single piece if that is easier. The Öhlins exploded view names the number for each position; we can look it up if you do not have it.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003e05666-18 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. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. A worn valve bleeds damping away without any visible symptom.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eIf you would rather not open the damper yourself, we can do it — we are an authorised Öhlins service centre and rebuild these units as a matter of routine.\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 05666-18\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":53649252614410,"sku":"05666-18","price":1163.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/05666-18_ea42534e-1de3-4b57-b356-082d9c807036.png?v=1788874504","url":"https:\/\/inter-pace.com\/en-tw\/products\/ohlins-valve-assy-dia-1-8-bleed-4-0-05666-18","provider":"Inter-Pace","version":"1.0","type":"link"}
