Funktion
Öhlins gibt für diese Position Innendurchmesser 40 mm, Schnurstärke 5 mm, Werkstoff FKM 70 an. Nach dem Einbau wird die Einheit kurz durchgefedert, bevor sie unter Druck gesetzt wird. O-Ringe werden über den Innendurchmesser und die Schnurstärke bestimmt, nicht über den Außendurchmesser. Eine Dichtung, die einmal trocken gelaufen ist, bleibt beschädigt, auch wenn wieder Öl anliegt.
Original-Öhlins-Teil
Der Wert eines Öhlins-Fahrwerks liegt in seiner Wartbarkeit — Ersatzteile gibt es für Baureihen, die längst aus dem Programm sind. Öhlins fertigt Serviceteile in denselben Toleranzen wie die Erstausrüstung; ein Nachbau trifft die Passung selten. Sie können die Nummer auch mit der Rechnung der letzten Wartung abgleichen. Wir liefern das Teil so, wie Öhlins es führt — ohne Umverpackung, ohne Zwischenhandel.
Undichtigkeit zeigt sich zuerst als Ölfilm auf der Welle, dann als Tropfen. Der Werkstoff muss zur Öltemperatur passen, sonst härtet der Ring aus. Teile aus dem Servicekatalog tragen dieselben Werkstoffe wie die Erstbestückung, nicht nur dieselben Maße. Ein O-Ring wird über Innendurchmesser und Schnurstärke bestimmt, nie über den Außendurchmesser.
Zuordnung über die Nummer
Bestellt wird unter 00438-27. Wo sich mehrere Größen eine Bezeichnung teilen, trennt sie nur die Nummer. An Verstellern sitzen O-Ringe an beweglichen Stellen und verschleißen dort schneller.
Einbau und Abstimmung
Der Tausch dieser Position gehört in geübte Hände: Vorspannung, Dichtsitz und Füllmenge müssen anschließend stimmen. Als autorisiertes Öhlins-Service-Center erledigen wir das für Sie — melden Sie sich gern.
