Was es ist
Maßlich ist das Teil mit Innendurchmesser 54 mm, Schnurstärke 4 mm, Werkstoff NBR 70 beschrieben. Beim Einbau wird der Ring geölt, damit er beim Fügen nicht einreißt. Nach dem Einbau wird die Einheit kurz durchgefedert, bevor sie unter Druck gesetzt wird. Undichtigkeit zeigt sich zuerst als Ölfilm auf der Welle, dann als Tropfen.
Warum das Originalteil
Wer sein Fahrwerk regelmäßig warten lässt, kommt mit wenigen Positionen aus; wer wartet, tauscht ganze Baugruppen. Eine korrekt bestückte Überholung stellt das Ansprechverhalten wieder her, das ein müder Dämpfer verloren hat. Serienmäßige Positionen halten wir vorrätig; Sonderteile bestellen wir gezielt. Maßgeblich ist die Nummer; Bezeichnungen wiederholen sich bei Öhlins über verschiedene Größen hinweg.
Öhlins hält Positionen oft über Modellgenerationen hinweg gleich, tauscht aber ohne Ankündigung Werkstoffe. Verschleiß zeigt sich zuerst an den Dichtflächen; Riefen dort bedeuten meist, dass mehr als eine Position fällig ist. Teile aus dem Servicekatalog tragen dieselben Werkstoffe wie die Erstbestückung, nicht nur dieselben Maße.
So passt es sicher
Der verlässliche Weg führt über die Explosionszeichnung: Position suchen, Nummer ablesen, bestellen — hier 00338-90. Die Dichtung hält das Öl im System und den Schmutz draußen. O-Ringe werden über den Innendurchmesser und die Schnurstärke bestimmt, nicht über den Außendurchmesser.
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.
