the screw size is an issue in itself.
The mounting torque of the smaller one (MF10 x X) is 75 Nm, while the larger one MF12 x X) gets 120 Nm.
If the smaller one was overtorqued you can even see with bare eyes that it is lengthened.
To fix this screw correctly, directly impacts the function of the starters freewheel clutch.
It must be done very seriously with the smaller screw, while the larger one has more reserve in it.
