Piston bands are consumables — they wear against the bore and lose their seal gradually. A check valve holds pressure in one direction and opens in the other; a worn one lets damping bleed away. Jets meter fixed bleed flow and are sized in tenths of a millimetre.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eÖhlins lists this part under its own number in the service catalogue so a workshop can order exactly what it needs. The alternative to a service part is usually a new damper, which is why this catalogue exists. Order by part number. The dimensions below are the ones Öhlins publishes for it. Where a number has been superseded, Öhlins states the replacement — we pass that on.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eOrder under 04798-02. Where several sizes share a description, only the number separates them. Where no measurement is given, the drawing position is what identifies the part. Twin-tube pistons have separate paths for compression and rebound, which is the whole point of the design. 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\u003eÖhlins recommends that its units are serviced by an authorised centre. We are one: rebuild, revalve and setup all happen in our own workshop.\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 04798-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Piston Bands\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":53649078911242,"sku":"04798-02","price":15.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/04798-02_9281b64a-39e1-463c-88f9-16efb580dfb8.png?v=1788873594","url":"https:\/\/inter-pace.com\/en-ge\/products\/ohlins-piston-ring-04798-02","provider":"Inter-Pace","version":"1.0","type":"link"}
