In the manual it shows it to be the same as a 990. It looks to be rusted onto the shaft. This end of the u-joint is suppose to float on the pump shaft, allowing for any movement lengthwise and for drive shaft installation and removal.
These can be a real chore to remove. One member made a puller just for this. I have used a crow bar and a BFH to drive it off from the rear. Try driving the shaft towards the pump to get some movement started. Use PB Blaster or Kroil to help penetrate the rust. It may take days to work it loose.
