First, close the bleed screw and turn the machine upside down.
You will then see 3 vertical bolts at the rear which fasted the pump bracket to the underside of the end cover, and a horizontal bolt at the top of the motor end cover.
Remove these 4 bolts and the complete assembly lifts clear.
There are two O-Rings in the top of the pump bracket, these can be reused.
