Thread pitch is specific to the tube — caps are not interchangeable between units. A worn end eye bearing is a common source of rear-end vagueness that gets blamed on damping. Spherical bearings in the eye let the damper move without binding as the linkage arcs.\u003c\/p\u003e\u003ch2\u003eGenuine Service Part\u003c\/h2\u003e\u003cp\u003eThe tolerances here are the ones the unit was assembled to, not a pattern equivalent's interpretation of them. Öhlins supports units that are decades old, which is why the spare parts list runs to thousands of numbers. If you are unsure which number your unit takes, send us the model and serial number of the damper and we will look it up. We can supply the whole position from the drawing rather than the single piece if that is easier.\u003c\/p\u003e\u003ch2\u003eHow to Be Sure It Fits\u003c\/h2\u003e\u003cp\u003eThe reliable route is the exploded drawing: find the position, read the number, order it — 21807-01 in this case. Öhlins states dimension a 1 mm, dimension b 21 mm for this number, and those figures are the deciding ones. Öhlins machines the eye from the same billet as the body on many units. The spherical bearing in an end eye lets the damper follow the linkage without side load.\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 21807-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e End Caps\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 21 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eThread:\u003c\/em\u003e M46x1\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":53651688882442,"sku":"21807-01","price":66.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21807-01_c00c3ba3-35ce-4e86-b2bd-3c6ee6f72922.png?v=1788877832","url":"https:\/\/inter-pace.com\/en-sr\/products\/ohlins-top-cap-m46x1-21-21807-01","provider":"Inter-Pace","version":"1.0","type":"link"}
