Funktion
Als Maß nennt Öhlins Dimension A 8 mm, Dimension B 25 mm. Die Anzahl der Bohrungen ist Teil der Abstimmung und unterscheidet sonst gleiche Kolben. Die Anzahl der Bohrungen unterscheidet sonst gleich aussehende Kolben. Öhlins stimmt Kolben und Shimpaket als Einheit ab; einzeln getauscht ändert sich die Charakteristik.
Warum das Originalteil
Öhlins hält seine Fahrwerke über Einzelteile am Leben; deshalb lässt sich ein fünfzehn Jahre altes Federbein noch überholen statt ersetzen. Verschleiß zeigt sich zuerst an den Dichtflächen; Riefen dort bedeuten meist, dass mehr als eine Position fällig ist. Bestellt wird über die Artikelnummer. Die Maße darunter sind die, die Öhlins selbst veröffentlicht. Kommt die Einheit ohnehin auf die Werkbank, lohnt es sich, die benachbarten Verschleißteile mitzubestellen.
Ein Dämpfer ist kein Verschleißteil im Ganzen, sondern eine Baugruppe aus Teilen, die einzeln getauscht werden können. Der Kolben teilt den Zylinder in zwei Kammern und trägt die Durchflusskanäle.
So passt es sicher
Neben der Nummer 02520-80 hilft der Maßvergleich: Wo Öhlins Größen fein staffelt, entscheidet ein Millimeter. Die Auflagefläche für die Shims muss eben sein, sonst schließt das Paket nicht sauber. Öhlins fertigt Kolben mit engen Toleranzen zum Zylinder, damit kein Öl vorbeiströmt.
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.
