I need to replace my pool pump, Century.  See attached photos of pump and motor sides.  Can you please provide a part list so I can order?

Looks like the pump is 193993-05 and the pump is a Jandy SHPM 1.5?

Photos attached.

Ok - can you send me a "cart" like you did before of all that I should buy so I can get it ordered?  Thanks!

If it is leaking between the seal plate and motor (keys 1 &2), the issue is usually the shaft seal. Maybe it wasn't in there 100% flush and over time, it moved. The only other reason it would leak there is a cracked seal plate, but that would be rare.

A faulty backplate o-ring would cause a leak between the seal plate and pump housing (keys 2 & 6). The diffuser o-ring would not cause a leak.

Uh oh, now it is leaking?!  I noticed that there was water coming out the bottom of the joint between the motor and the pump housing.  This is new and it worked fine for the last month.  I ordered the kit you suggested and used my old gaskets/orings.  Could this be the cause of it?  Could the shaft seal?  How can I tell. . and, if I am going to take it apart to replsce the o-ring and diffuser ring should I replace the shaft seal again just to make sure?  Thanks!

I replaced it on Sunday and it all went smooth.  No issues and I enjoyed doing it.  Thanks for your help.

There are two o-rings that can be replaced while you have the pump open, the backplate o-ring and diffuser o-ring. The backplate o-ring is part number 5020-136 and the diffuser o-ring is part number R0622000.

I ordered the pump and the shaft seal.  Do I need gaskets or orings (or whatever) for between the motor housing and the pump side?

We recommend replacing the shaft seal when you replace the motor. The shaft seal for your Jandy Stealth pump is part number 5020-087.
