Am hinteren Ende Der Ölwanne wird das Ball Cap angeschraubt. In dieser Kappe befindet sich das vierte Hauptlager. Darum ist es auch wichtig, dass die Ölwanne nicht verbogen ist, sonst fluchtet dieses vierte Lager nicht mit den drei Hauptlager der Kurbelwelle.
Auch das vierte Lager ist ein gegossenes Weißmetalllager. Genau an diesem Lager hatte ich immer den hohen Ölverlust. Jetzt schauen wir uns das Lager mal genau an.
At the rear end of the oil pan, the ball cap is screwed on. This cap contains the fourth main bearing. Therefore, it is also important that the oil pan is not bent, otherwise this fourth bearing will not align with the three main bearings of the crankshaft.
The fourth bearing is also a cast white metal bearing. This is the bearing where I always had the high oil loss. Now let's take a close look at the bearing.
The oil loss could also be caused by a missing cap in the clutch shaft. However, this cap is present.
However, if you look closely at the bearing, you will notice that the bearing cup has come loose and can even be moved in the cap.
The bearing must be renewed. An alternative would be a modern solution with a sealed ball bearing. Normally I think that you should not improve a historic car with modern parts just because you can. I mean, for example, if I want a car with brakes on all wheels, I'll just buy a Model A instead of a Model Ts. But in this case it's not about comfort or performance, it's about stopping oil loss. That's enough reason to think about this improvement. Unfortunately, this bearing is currently not available from all suppliers. So the original bearing will be repaired first. The ball bearing can also be installed later.
