How much fore and aft motion should there be at the output flange? I measure 1/16". I also listened with a mechanics stethoscope and didn't hear anything. The engine cradle was particularly quiet, which tells me it isn't the A4 causing the vibration we feel. I don't this stethoscope has much low frequency response though.
I'm working on pulling the shaft now. I think I'll have to take the coupling off to separate it from the motor.
