does the lower spray arm on a kitchenaid model KDS-18 just lift up off the shaft? does the shaft just lift up out of the pump? why is the end of the shaft that goes in the pump knurled? thanks

The spray arm under the lower rack does just lift off.

The shaft should not just pull out it is a part of the lower spray arm support assembly.

Here is a link to your dishwasher model kds18.
