Was es ist
Als Maß nennt Öhlins Innendurchmesser 18.72 mm, Schnurstärke 2.62 mm, Werkstoff NBR 70. Beim Einpressen darf die Dichtung nicht verkanten, sonst ist sie sofort undicht. Der Werkstoff ist auf die Öltemperatur abgestimmt, die im Betrieb entsteht. Eine Dichtung, die einmal trocken gelaufen ist, bleibt beschädigt, auch wenn wieder Öl anliegt.
Echtes Serviceteil
Eine korrekt bestückte Überholung stellt das Ansprechverhalten wieder her, das ein müder Dämpfer verloren hat. Bei Dichtungen und Führungen entscheidet ein Hundertstel Millimeter darüber, ob die Einheit dicht bleibt. 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 Ersatzteilliste folgt der Explosionszeichnung; jede Position hat ihre eigene Nummer, auch wenn zwei Teile gleich aussehen. Ein O-Ring altert auch ungenutzt; das Herstellungsdatum steht auf der Verpackung. Öhlins hält seine Fahrwerke über Einzelteile am Leben; deshalb lässt sich ein fünfzehn Jahre altes Federbein noch überholen statt ersetzen.
Zuordnung über die Nummer
Neben der Nummer 00438-23 hilft der Maßvergleich: Wo Öhlins Größen fein staffelt, entscheidet ein Millimeter. O-Ringe werden über den Innendurchmesser und die Schnurstärke bestimmt, nicht über den Außendurchmesser. Der Werkstoff muss zur Öltemperatur passen, sonst härtet der Ring aus.
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.
