Wo es sitzt
Als Maß nennt Öhlins Durchmesser 25 mm, Länge 299 mm. Die Innenfläche ist gehont; ihre Rauheit entscheidet darüber, wie lange die Dichtung hält. Das Rohr führt den Kolben und nimmt den Druck auf, den die Dämpfung erzeugt. Bei Zweirohrsystemen trägt das äußere Rohr keine Dämpfung, sondern führt das Öl zurück.
Warum das Originalteil
Die Ersatzteilliste folgt der Explosionszeichnung; jede Position hat ihre eigene Nummer, auch wenn zwei Teile gleich aussehen. Wer sein Fahrwerk regelmäßig warten lässt, kommt mit wenigen Positionen aus; wer wartet, tauscht ganze Baugruppen. Die Angaben stammen aus der aktuellen Öhlins-Serviceliste, nicht aus älteren Katalogen. Serienmäßige Positionen halten wir vorrätig; Sonderteile bestellen wir gezielt.
Ein Dämpfer ist kein Verschleißteil im Ganzen, sondern eine Baugruppe aus Teilen, die einzeln getauscht werden können. Öhlins ändert Teile im Laufe einer Baureihe; die Nummer, nicht das Baujahr, sagt, was passt. Bei größeren Überholungen prüfen wir vorab, welche Positionen zusammengehören. Teile aus dem Servicekatalog tragen dieselben Werkstoffe wie die Erstbestückung, nicht nur dieselben Maße.
Die richtige Nummer finden
Öhlins führt diese Position in der Explosionszeichnung der zugehörigen Einheit unter 21624-02. Nach einem Sturz lohnt die Prüfung auf Verzug, auch wenn das Rohr äußerlich unbeschädigt wirkt. Die Wandstärke ist so gewählt, dass sich das Rohr unter Druck nicht aufweitet.
Einbau und Abstimmung
Als autorisiertes Öhlins-Service-Center bauen wir das Teil auf Wunsch ein und stellen die Einheit anschließend auf Fahrer und Einsatz ein. Eine Anfrage genügt.
