Es hilft ja nichts, ich muss noch mal den Lüfter ausbauen um das Problem mit der Feststellschraube zu lösen. Die kleine Schraube vibriert sich leider immer wieder los. Wenn sich diese kleine Schraube löst, dreht der Lüfter die Lüfterachse in den Spannhebel und klemmt den Lüfter fest. Dann kocht das Kühlwasser im Stand, wie gestern an der Tankstelle.
It does not help, I have to remove the fan again to solve the problem with the locking screw. Unfortunately the small screw vibrates loose again and again. If this small screw loosens, the fan turns the fan shaft into the clamping lever and clamps the fan. Then the cooling water boils while standing, like yesterday at the gas station.
Mein Plan ist es in die Achse ein kleines Sackloch zu bohren, in das die Schraube dann eingreift. Ich hoffe, dass die Feststellschraube dann besser hält.
My plan is to drill a small blind hole in the axle, in which the screw then engages. I hope that the locking screw will then hold better.
If that doesn't help, that's not so bad either. I have to replace the axle anyway. First of all the thread at the end is broken. The tension lever and the grease nipple are screwed onto this thread. For the tension lever the thread is still good. But the grease nipple does not hold anymore. If the thread is intact, the grease nipple would serve as a lock nut. I believe that the locking screw is not original.
In addition, the fan axle is strongly run in. There will be a new one with the next parts delivery.
If the axle is replaced, I could also replace the two brass bearings in the fan.
This was only a small repair. After that we went straight back on the road.
