DescriptionThe whole story▼
Zylinderkopf TTX36, Öhlins Artikelnummer 21070-28. In ihm sitzen Dichtung und Führung, oft als eine Baugruppe.
Wichtigste Merkmale
- Öhlins Artikelnummer 21070-28
- Original Öhlins Serviceteil
Was es ist
Die Zuordnung läuft über die Nummer, nicht über ein Maß. Die Wandstärke ist so gewählt, dass sich das Rohr unter Druck nicht aufweitet. Riefen im Rohr bedeuten Ölverlust, auch wenn die Dichtung neu ist. Die Innenfläche ist gehont; ihre Rauheit entscheidet darüber, wie lange die Dichtung hält.
Echtes Serviceteil
Bei Dichtungen und Führungen entscheidet ein Hundertstel Millimeter darüber, ob die Einheit dicht bleibt. Die Einheit ist nur so gut wie ihre kleinste Passung; deshalb lohnt sich das Originalteil auch an unscheinbarer Stelle. Die Nummer steht in der Explosionszeichnung der Einheit; danach ist die Bestellung eindeutig. Bei mehreren gleich beschriebenen Größen entscheidet allein die Nummer, welche gemeint ist.
Kanäle im Kopf verbinden Zylinder und Ausgleichsbehälter. Bestellt wird über die Artikelnummer. Die Maße darunter sind die, die Öhlins selbst veröffentlicht. Eine Überholung ist günstiger als ein neues Federbein, solange die tragenden Teile in Ordnung sind. Die Bohrung für die Welle ist enger toleriert als die Außenkontur.
Die richtige Nummer finden
Ist die Einheit bereits geöffnet, lohnt der Abgleich der Maße unten mit dem Teil in der Hand, bevor 21070-28 bestellt wird. Die Oberfläche wird nach dem Honen gespült, damit kein Schleifrückstand ins Öl gerät. Die Rohrlänge legt den möglichen Hub fest und ist deshalb je Einheit verschieden.
Einbau und Abstimmung
Wir empfehlen, den Einbau von einem autorisierten Öhlins-Service-Center vornehmen zu lassen. Wir sind selbst eines und bieten die Arbeit an; fragen Sie einfach an.
