Was es ist
Ein Maß gibt es hier nicht zu prüfen — Nummer und Explosionszeichnung bestimmen die Position. Sein Sitz im Rohr ist eine eigene Dichtstelle mit eigenem O-Ring. Der Werkstoff ist auf die Öltemperatur abgestimmt, die im Betrieb entsteht. Der Dichtkopf fasst Wellendichtring, Staubdichtung und Führung zusammen.
Echtes Serviceteil
Teile aus dem Servicekatalog tragen dieselben Werkstoffe wie die Erstbestückung, nicht nur dieselben Maße. Wer sein Fahrwerk regelmäßig warten lässt, kommt mit wenigen Positionen aus; wer wartet, tauscht ganze Baugruppen. Wer die Einheitsnummer des Federbeins kennt, bekommt von uns die passende Teileliste dazu. Wir sind offizieller Öhlins-Vertriebspartner und beziehen die Teile direkt.
Bei mehreren gleich beschriebenen Größen entscheidet allein die Nummer, welche gemeint ist. Wer die Einheit selbst zerlegt, sollte die Nummern vor dem Ausbau notieren; hinterher sind sie schwer zu lesen. Die Vorspannung der Lippe kommt von einer eingelegten Ringfeder. Kommt die Einheit ohnehin auf die Werkbank, lohnt es sich, die benachbarten Verschleißteile mitzubestellen. Ihre Lippe läuft auf der Welle und verschleißt mit jedem Zentimeter Hub.
Die richtige Nummer finden
Der verlässliche Weg führt über die Explosionszeichnung: Position suchen, Nummer ablesen, bestellen — hier 21754-01. Ein undichter Dichtkopf zeigt sich als Ölfilm auf der Welle, lange bevor es tropft.
Einbau und Abstimmung
Eine Dämpferüberholung ist Werkstattarbeit: Die Einheit muss zerlegt, das Shimpaket in der richtigen Reihenfolge wieder aufgebaut und die Gasfüllung neu gesetzt werden. Wir sind autorisiertes Öhlins-Service-Center und übernehmen das komplett — sprechen Sie uns an.
