Default Starter motor

The last week the starter motor was turning over very slowly, almost not being able to start the engine. So i measured the battery voltage, which was ok at 12.7V, checked the wires, grounds and connections. All was ok. So today i removed the starter motor and found the brushes worn to almost nothing. But also the positive stud threads are almost gone, but doesn´t show signs of overheating.
What i think is strange, that there are four places for the field windings, but only three of them are in use. Didn´t have time yet to find out if this is normal, at least the starter motor was working fine until now. I have new brushes , but have to see if the positive stud is ok for re-use.
Edit: I just checked the manual and see that it is normal to only have three coils.
