there are literally 100's of these motor/reduction/jung pumps out there, Premacon uses the exact same combo in their models, Cooper has this exact same motor - pump in his china hoe... I'm just livid... another 2 month delay...

Thank God for my JD850.

One is a fluke, 2 failures of common system is a red flag for sure. I don't have good enough pic quality to say for sure, looks like clean break? Or do I see beach marks and signs of a flaw ?
Failed bearing , now shaft? Something ain't straight.

Right where it snapped, there's an E clip flush with the face of the motor, a wee bit of material gone.

I've snapped 6mm shafts before & it's always where an E clip is placed... pinions on trk axles, output shaft of swing motor on 850, ect... but those times the shafts had seen a lot of torture as well.
