Bosch circulator rebuild

The circulator failed on my 5-6 yr old bosck dishwasher. I ordered a new pump and tried replacing it, I got 99% of the way through and then broke the tab on the plastic base plate of the pump that keeps the motor from turning too far relative to the motor. I just ordered a mew base plate - any suggestions on how to remove the bad pump base and install the new? There does not seem to be any obvious way that it comes apart.

The instructions are attached to the reply.

Thanks, this looks like just what I need - (If only I had posted on the forum before my first attempt…)

You are welcome. Keep us posted.
