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.

Thanks!

The replacement motor is model B841 (B2841). The replacement is a full rated 1HP motor with a total HP rating of 1.65.

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

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?

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

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!

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.

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