Hello all,
I recently bought an used 913 d2 driver where after a few shots the head become a bit loose on the shaft, as the screw is not tight.
My idea is that some washer is missing or is not in the exact position, but I can't find anywhere how the single pieces shall be mounted.
To keep the screw tight I have : a rubber washer and an iron washer which is not flat but has a small border on a side.
My idea was : iron washer under the screw head, set in the way the head come inside the little border - then the drive head and the rubber washer at the end, before the shaft adapter.
Is that right ? Some washer is missing? Could be another problem?
Thank you
Lapo
