4200XL Pump Motor Problem

[A1 Dirt]

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.
