Funktion
Nach Öhlins-Angabe: Innendurchmesser 32.1 mm, Schnurstärke 1.6 mm, Werkstoff NBR 90. Werkstoffe wie NBR und FKM unterscheiden sich in der Temperaturbeständigkeit deutlich. Ein Dichtkopf fasst Wellendichtring, Staubdichtung und Führung in einer Baugruppe zusammen. Sie ist das Teil, das bei einer Überholung am häufigsten getauscht wird.
Original-Öhlins-Teil
Teile aus dem Servicekatalog tragen dieselben Werkstoffe wie die Erstbestückung, nicht nur dieselben Maße. Die Ersatzteilliste folgt der Explosionszeichnung; jede Position hat ihre eigene Nummer, auch wenn zwei Teile gleich aussehen. Die Nummer steht in der Explosionszeichnung der Einheit; danach ist die Bestellung eindeutig. Maßgeblich ist die Nummer; Bezeichnungen wiederholen sich bei Öhlins über verschiedene Größen hinweg.
Die Angaben stammen aus der aktuellen Öhlins-Serviceliste, nicht aus älteren Katalogen. Öhlins hält Positionen oft über Modellgenerationen hinweg gleich, tauscht aber ohne Ankündigung Werkstoffe. Öhlins ändert Teile im Laufe einer Baureihe; die Nummer, nicht das Baujahr, sagt, was passt. Sie können die Nummer auch mit der Rechnung der letzten Wartung abgleichen.
Zuordnung über die Nummer
Wer unsicher ist, misst nach — die Angaben unten stammen aus der Öhlins-Serviceliste, 00638-73 ist die zugehörige Nummer. Die Nut gibt die Verpressung vor; zu wenig dichtet nicht, zu viel zerstört den Ring. Undichtigkeit zeigt sich zuerst als Ölfilm auf der Welle, dann als Tropfen.
