| older models from before WW2 mostly, but
not always had the dynamo centered on the carter by the carter reaching
into the back of the dynamo. For this you need:system 73 23 799 |
we also had cases of engines made in 1938/39
where the Noris dynamo was shaped as in later models as shwon here (dynamo
centering reaching into carter by help of am elevated dynamo rim) but
with crank as shown in system 7323 you need: system 78 27 799 |
| Here the back of the dynamo has a INWARDLY recess. | Here your stock dynamo has some ELEVATED rim |
 |

| The carter in turn has some elevated rim which enters the dynamo | the carter in turn has a flat seat with centering opening into engine carter. |

| For models after WW2 you
will need system 70 45 799

your Zundapp from before WW2 needs this system. |

Zündapp did produce DB(K) models both before and after WW2. Engines
may look very similar, but the specific type of the Noris
dynamo was different and will NOT fit the other. Here is some guide
on how to find out what you have. Please
do not rely on year of make (or what you think this year is).
Imperatively check the stock hardware against the following information
