Turn off the main breaker for the HPU. Manually activate the unclamp/clamp solenoids to relieve any pressure from the system.
Unbolt and lower the sensor/anti-rotation bracket . Remove the snap ring  from the shaft. Outside snap ring pliers with at least 2 inches of travel between the tips are necessary.
Lower the block  off the shaft. If it is difficult to remove the block, verify the HPU pressure is low and remove the hydraulic lines to release any residual pressure. The block should drop down easily after the lines are off.
Install jack bolts  under the clamp plate to prevent damage to the piston quad-ring.
Remove the (8) bolts  from the receiver.
Install (2) eyebolts in the clamp plate. Use an appropriate lifting strap to raise the receiver from the rotary.
Note: Hydraulic oil will leak out when the receiver is lifted.
