Was es ist
Nach Öhlins-Angabe: Innendurchmesser 135.76 mm, Schnurstärke 1.78 mm, Werkstoff NBR 70. Werkstoffe wie NBR und FKM unterscheiden sich in der Temperaturbeständigkeit deutlich. Undichtigkeit zeigt sich zuerst als Ölfilm auf der Welle, dann als Tropfen. Die Nut gibt die Verpressung vor; zu wenig dichtet nicht, zu viel zerstört den Ring.
Warum das Originalteil
Ein überholtes Federbein arbeitet wieder mit der Dämpfung, die im Datenblatt steht — vorausgesetzt, die Teile stimmen. Wer eine Einheit überholt, tauscht selten alles: meist entscheiden wenige Positionen darüber, ob die Dämpfung wieder stimmt. Bei Unsicherheit über die richtige Position hilft ein Blick in die Serviceunterlagen der Einheit. Maßgeblich ist die Nummer; Bezeichnungen wiederholen sich bei Öhlins über verschiedene Größen hinweg.
Beim Einpressen darf die Dichtung nicht verkanten, sonst ist sie sofort undicht. Zwischen Dichtung und Führung sitzt oft ein Stützring gegen Spaltextrusion. Die Angaben stammen aus der aktuellen Öhlins-Serviceliste, nicht aus älteren Katalogen.
Zuordnung über die Nummer
Die Nummer 00438-72 ist eindeutig; die Bezeichnung allein ist es nicht, weil Öhlins ähnliche Wortlaute über mehrere Größen verwendet. Ein O-Ring altert auch ungenutzt; das Herstellungsdatum steht auf der Verpackung. Die Vorspannung der Lippe kommt von einer eingelegten Ringfeder.
Einbau und Abstimmung
Wir empfehlen, den Einbau von einem autorisierten Öhlins-Service-Center vornehmen zu lassen. Wir sind selbst eines und bieten die Arbeit an; fragen Sie einfach an.
