Wall thickness and bore finish are what let a cylinder hold pressure without deforming under load. Head and tube are matched by thread and diameter; neither is interchangeable across units. A head that has been over-tightened distorts and stops sealing.\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. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. We can supply the whole position from the drawing rather than the single piece if that is easier. Tell us the damper's model designation and year and we will match the number for you.\u003c\/p\u003e\u003ch2\u003eGetting the Number Right\u003c\/h2\u003e\u003cp\u003eÖhlins identifies this position by the number 00870-55 in the exploded view for the unit it belongs to. The published dimensions are diameter 46 mm, length 26 mm — measure the old part against them if you are unsure. Surface finish is specified in microns, because it decides how quickly the piston band wears. 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\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 00870-55\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":53648959439114,"sku":"00870-55","price":205.33,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/00870-55_66e82047-b1c8-43ba-9c2f-feea73e267ae.png?v=1788872781","url":"https:\/\/inter-pace.com\/products\/ohlins-cylinder-head-348-pb-46-26-00870-55","provider":"Inter-Pace","version":"1.0","type":"link"}
