Re: 4200XL Pump Motor Problem
you did the right thing with a cone point set screw . I highly doubt a flat will keep it from running off the shaft like that . that motor does seem to have excess vibration
 . could be crap bearings a batch of bad mag cases (running out )

Re: 4200XL Pump Motor Problem
The cone points did not hold.
As a last resort, I used Loctite 290 as a retaining compound. So far, it's held through four batteries. Hopefully that was the fix. There is still some intermittent noise when the motor/pump is under load. You do not hear this noise in the video. It's much louder. Since the motor is running OK, I now believe the source of the noise is the hydraulic pump. There is no air in the system so that's not the problem. It's probably bearings going out.
