DescriptionThe whole story▼
O-Ring 27.7x1.9, Öhlins Artikelnummer 04722-30. Ein O-Ring wird über Innendurchmesser und Schnurstärke bestimmt, nie über den Außendurchmesser.
Wichtigste Merkmale
- Öhlins Artikelnummer 04722-30
- Schnurstärke 1.9 mm
- Innendurchmesser 27.7 mm
- Original Öhlins Serviceteil
Funktion
Nach Öhlins-Angabe: Innendurchmesser 27.7 mm, Schnurstärke 1.9 mm. Beim Einpressen darf die Dichtung nicht verkanten, sonst ist sie sofort undicht. Nach dem Einbau wird die Einheit kurz durchgefedert, bevor sie unter Druck gesetzt wird. Undichtigkeit zeigt sich zuerst als Ölfilm auf der Welle, dann als Tropfen.
Warum das Originalteil
Öhlins fertigt Serviceteile in denselben Toleranzen wie die Erstausrüstung; ein Nachbau trifft die Passung selten. Ein überholtes Federbein arbeitet wieder mit der Dämpfung, die im Datenblatt steht — vorausgesetzt, die Teile stimmen. Für die Überholung einer kompletten Einheit stellen wir den Teilesatz auf Wunsch zusammen. Kommt die Einheit ohnehin auf die Werkbank, lohnt es sich, die benachbarten Verschleißteile mitzubestellen.
Fotos der ausgebauten Position helfen uns, die Nummer zu bestätigen, bevor Sie bestellen. Was nicht am Lager liegt, ordern wir bei Öhlins nach; die Laufzeit nennen wir vor der Bestellung. Maßgeblich ist die Nummer; Bezeichnungen wiederholen sich bei Öhlins über verschiedene Größen hinweg.
Die richtige Nummer finden
Der verlässliche Weg führt über die Explosionszeichnung: Position suchen, Nummer ablesen, bestellen — hier 04722-30. An Verstellern sitzen O-Ringe an beweglichen Stellen und verschleißen dort schneller. Die Nut gibt die Verpressung vor; zu wenig dichtet nicht, zu viel zerstört den Ring.
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.
