DescriptionThe whole story▼
Zylinderkopf 46, Öhlins Artikelnummer 21159-02. Nach einem Sturz lohnt die Prüfung auf Verzug, auch wenn das Rohr äußerlich unbeschädigt wirkt.
Wichtigste Merkmale
- Original Öhlins Serviceteil
- Öhlins Artikelnummer 21159-02
Was es ist
Die Zuordnung läuft über die Nummer, nicht über ein Maß. Sein Gewinde nimmt das volle Anzugsmoment auf; ein verzogenes Gewinde macht die Einheit undicht. Die Innenfläche ist gehont; ihre Rauheit entscheidet darüber, wie lange die Dichtung hält. Die Bohrung für die Welle ist enger toleriert als die Außenkontur.
Original-Öhlins-Teil
Öhlins hält seine Fahrwerke über Einzelteile am Leben; deshalb lässt sich ein fünfzehn Jahre altes Federbein noch überholen statt ersetzen. Bei Dichtungen und Führungen entscheidet ein Hundertstel Millimeter darüber, ob die Einheit dicht bleibt. Sie können die Nummer auch mit der Rechnung der letzten Wartung abgleichen. Fotos der ausgebauten Position helfen uns, die Nummer zu bestätigen, bevor Sie bestellen.
Das Rohr führt den Kolben und nimmt den Druck auf, den die Dämpfung erzeugt. An der Aufnahme für den Ausgleichsbehälter sitzt eine eigene Dichtstelle. Wer die Einheit selbst zerlegt, sollte die Nummern vor dem Ausbau notieren; hinterher sind sie schwer zu lesen.
Zuordnung über die Nummer
Die Nummer 21159-02 ist eindeutig; die Bezeichnung allein ist es nicht, weil Öhlins ähnliche Wortlaute über mehrere Größen verwendet. Riefen im Rohr bedeuten Ölverlust, auch wenn die Dichtung neu ist. Die Oberfläche wird nach dem Honen gespült, damit kein Schleifrückstand ins Öl gerät.
Einbau und Abstimmung
Der Tausch dieser Position gehört in geübte Hände: Vorspannung, Dichtsitz und Füllmenge müssen anschließend stimmen. Als autorisiertes Öhlins-Service-Center erledigen wir das für Sie — melden Sie sich gern.
