Measure the old part against them before ordering. Öhlins offers several lengths so the same body can serve different springs. Hydraulic preload adjusters are sealed units and are replaced rather than opened. The adjuster knob is what the rider touches, and Öhlins colour-codes it by function.\u003c\/p\u003e\u003ch2\u003eOriginal Öhlins Part\u003c\/h2\u003e\u003cp\u003eBuying the individual part rather than a complete assembly is what makes servicing an Öhlins unit worthwhile. Öhlins supports its suspension with individual service parts, which is why a fifteen-year-old damper can still be rebuilt to specification. The exploded drawing for your unit names the number; if you do not have it, we do. We can check the number against the Öhlins exploded view before you order — just ask.\u003c\/p\u003e\u003ch2\u003eIdentifying the Right Part\u003c\/h2\u003e\u003cp\u003ePart number 21632-02 is unambiguous; the description alone is not, because Öhlins uses similar wording across sizes. Öhlins states dimension a 39 mm, dimension b 102 mm for this number, and those figures are the deciding ones. An adjuster that turns without resistance has lost its detent; the setting is then guesswork. The preload tube transfers the spring load to the adjuster and sets the installed length.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eFitting service parts means opening a pressurised unit. As an authorised Öhlins service centre we do that here, with the right tools and a dyno check afterwards — just ask.\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 21632-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eCategory:\u003c\/em\u003e Preload Tubes\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension A:\u003c\/em\u003e 39 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eDimension B:\u003c\/em\u003e 102 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":53652636467466,"sku":"21632-02","price":10.6,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/21632-02_4bf209d5-1845-4a36-9505-8726e35a3402.png?v=1788879777","url":"https:\/\/inter-pace.com\/products\/ohlins-preloadtube-polym-26-39-102-21632-02","provider":"Inter-Pace","version":"1.0","type":"link"}
