Wo es sitzt
Zu dieser Position nennt Öhlins kein Maß; maßgeblich ist die Zeichnung der Einheit. Die Anzahl der Bohrungen ist Teil der Abstimmung und unterscheidet sonst gleiche Kolben. Rückschlagventile lassen das Öl nur in eine Richtung passieren und formen so die Kennlinie. Kolben aus unterschiedlichen Baujahren sehen gleich aus und sind es nicht.
Original-Öhlins-Teil
Eine korrekt bestückte Überholung stellt das Ansprechverhalten wieder her, das ein müder Dämpfer verloren hat. Original-Serviceteile halten die Einheit in dem Zustand, für den Öhlins sie abgestimmt hat. Bei größeren Überholungen prüfen wir vorab, welche Positionen zusammengehören. Bestellt wird über die Artikelnummer. Die Maße darunter sind die, die Öhlins selbst veröffentlicht.
Öhlins ändert Teile im Laufe einer Baureihe; die Nummer, nicht das Baujahr, sagt, was passt. Bei hohen Kolbengeschwindigkeiten übernimmt das Ventil, bei niedrigen der Bypass. Wir liefern das Teil so, wie Öhlins es führt — ohne Umverpackung, ohne Zwischenhandel.
Wer die Einheitsnummer des Federbeins kennt, bekommt von uns die passende Teileliste dazu. Bei Dichtungen und Führungen entscheidet ein Hundertstel Millimeter darüber, ob die Einheit dicht bleibt. Zug- und Druckstufe haben getrennte Ventile.
So passt es sicher
Die Nummer 21625-01 ist eindeutig; die Bezeichnung allein ist es nicht, weil Öhlins ähnliche Wortlaute über mehrere Größen verwendet. Öhlins fertigt Kolben mit engen Toleranzen zum Zylinder, damit kein Öl vorbeiströmt. Verschleiß am Ventilsitz zeigt sich als weiche Dämpfung im ersten Teil des Hubs.
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.
