Wo es sitzt
Öhlins gibt für diese Position Innendurchmesser 39 mm, Schnurstärke 2 mm, Werkstoff NBR 90 an. Die Dichtung hält das Öl im System und den Schmutz draußen. Beim Einbau entscheidet die Sauberkeit: ein Staubkorn genügt für eine Undichtigkeit. Beim Lagern altern Dichtungen; Öhlins gibt deshalb Chargen mit Datum aus.
Original-Öhlins-Teil
Wer sein Fahrwerk regelmäßig warten lässt, kommt mit wenigen Positionen aus; wer wartet, tauscht ganze Baugruppen. Eine Überholung ist günstiger als ein neues Federbein, solange die tragenden Teile in Ordnung sind. Was nicht am Lager liegt, ordern wir bei Öhlins nach; die Laufzeit nennen wir vor der Bestellung. Ist die Nummer bekannt, ist die Zuordnung eindeutig — anders als bei der Beschreibung allein.
Die Staubdichtung hält Schmutz ab, dichtet aber nicht gegen Öldruck. Die Nummer steht in der Explosionszeichnung der Einheit; danach ist die Bestellung eindeutig. Eine Dichtung, die einmal trocken gelaufen ist, bleibt beschädigt, auch wenn wieder Öl anliegt.
Die richtige Nummer finden
00638-97 ist die Öhlins-Nummer für diese Position — dieselbe, die auch in den Serviceunterlagen steht. Werkstoffe wie NBR und FKM unterscheiden sich in der Temperaturbeständigkeit deutlich. Ein O-Ring wird über Innendurchmesser und Schnurstärke bestimmt, nie über den Außendurchmesser.
Einbau und Abstimmung
Wir raten dazu, die Einheit von einem autorisierten Öhlins-Service-Center öffnen zu lassen. Wir sind eines und bieten Überholung, Einbau und Abstimmung aus einer Hand an.
