Funktion
Als Maß nennt Öhlins Innendurchmesser 14 mm, Außendurchmesser 39 mm. Zwischen Dichtung und Führung sitzt oft ein Stützring gegen Spaltextrusion. Die Führung im Kopf nimmt Querkräfte auf und schützt so die Dichtlippe. Sein Sitz im Rohr ist eine eigene Dichtstelle mit eigenem O-Ring.
Echtes Serviceteil
Öhlins fertigt Serviceteile in denselben Toleranzen wie die Erstausrüstung; ein Nachbau trifft die Passung selten. Teile aus dem Servicekatalog tragen dieselben Werkstoffe wie die Erstbestückung, nicht nur dieselben Maße. Kommt die Einheit ohnehin auf die Werkbank, lohnt es sich, die benachbarten Verschleißteile mitzubestellen. Was nicht am Lager liegt, ordern wir bei Öhlins nach; die Laufzeit nennen wir vor der Bestellung.
Wer beim Zerlegen ohnehin offen ist, tauscht die Verschleißpositionen gleich mit — ein zweites Öffnen kostet mehr als das Teil. Wir sind offizieller Öhlins-Vertriebspartner und beziehen die Teile direkt. Öhlins setzt je nach Einbaulage unterschiedliche Profile ein. Sie ist das Teil, das bei einer Überholung am häufigsten getauscht wird.
So passt es sicher
Ist die Einheit bereits geöffnet, lohnt der Abgleich der Maße unten mit dem Teil in der Hand, bevor 21858-01 bestellt wird. Beim Einbau entscheidet die Sauberkeit: ein Staubkorn genügt für eine Undichtigkeit. Beim Einpressen darf die Dichtung nicht verkanten, sonst ist sie sofort undicht.
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.
