It is the part that keeps oil in and grit out, which is why it is replaced whenever the unit weeps.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOriginal Öhlins service part\u003c\/li\u003e\n\u003cli\u003eDiameter 46 mm\u003c\/li\u003e\n\u003cli\u003eÖhlins part number 00870-58\u003c\/li\u003e\n\u003cli\u003eLength 26 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Is\u003c\/h2\u003e\u003cp\u003eÖhlins publishes 46 mm, 26 mm for 00870-58 — the dimensions are the identity of the part. Length here is the working length, not the overall dimension, which is why two similar tubes are not interchangeable. Öhlins matches tube and piston as a pair during assembly, which is why the part numbers are specific. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eParts remain available years after a unit leaves the current price list, which is unusual in this trade. The part number is the contract: it defines material, dimension and finish together. Ask us before ordering if you are unsure: a wrong part in a pressurised unit is an expensive lesson. Send us the model and serial number of your unit and we will confirm the position before you order.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 00870-58 in this case. The published dimensions are diameter 46 mm, length 26 mm — measure the old part against them if you are unsure. Reservoir tubes carry the gas charge and are built to the same standard as the working cylinder. Öhlins turns and hones each tube to a defined roundness, because an out-of-round bore leaks past the piston.\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 00870-58\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Cylinder Heads\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDiameter:\u003c\/em\u003e 46 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 26 mm\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":53647920922890,"sku":"00870-58","price":290.87,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00870-58_ffc1e9c8-656b-4c69-9b79-8be7094cdf91.png?v=1788870216","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-head-19-pb-46-26-00870-58","provider":"Inter-Pace","version":"1.0","type":"link"}
