Valves and needles set the adjustable part of the damping; the piston sets the rest. Öhlins machines its pistons rather than sintering them, which is why the port edges stay sharp. Piston bands are consumables — they wear against the bore and lose their seal gradually.\u003c\/p\u003e\u003ch2\u003eWhy the Original\u003c\/h2\u003e\u003cp\u003eRebuilding to specification only works if the parts are to specification — that starts here. The alternative to a service part is usually a new damper, which is why this catalogue exists. If you are between two sizes, send us the measurement and we will check it against the catalogue. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21758-02 in this case. Öhlins states dimension a 1.25 mm, dimension b 32 mm for this number, and those figures are the deciding ones. Replacing a piston is a workshop job because the shim stack has to be rebuilt in the correct order. Valves and needles set the adjustable part of the damping; the piston sets the rest.\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 21758-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Valves\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 1.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 32 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M8x1.25\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":53652840972554,"sku":"21758-02","price":125.0,"currency_code":"BAM","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21758-02_f46f2ea7-0f3c-4f1d-aee2-d53c58f967e9.png?v=1788880207","url":"https:\/\/inter-pace.com\/en-ba\/products\/ohlins-adaptor-base-valve-m8x1-25-32-21758-02","provider":"Inter-Pace","version":"1.0","type":"link"}
