EC120 starter shaft sheared (TWICE) any ideas ?

Firstly may I wish everyone a happy and prosperous new year.

I have this problem and I,m hoping someone on here can maybe shed some light on it.
My 120 went in in July 11 for routine maintenance and had new brushes fitted to the starter / generator, all was well until within a few months and around 6 flight hours, the starter shaft broke at the shear point.
A good few weeks on the floor waiting for a new shaft to arrive, and again all was well...... Apart from this time it lasted less than 4 hrs / 4 weeks...... And it's sheared again....
I can't really tell if it's doing it on start up or spool down maybe,
I hit the starter button on both occasions and the starter didn't even attempt to turn the engine.
Both times the starter has been removed and the tempory engine turning tool used to make sure engine is free and not seized or stiff.....

Has anyone had this before, do any of you guys have any ideas, maybe even more important because you never know ! Do any of you have an APC 160SG140Q starter laying around so I don't have to wait weeks for one to come from the states ?

Appreciate any help /ideas ...

Best regards

Nelly.
