century pool motor st1102 slinger and washer for shaft

Hello, I purchased a Century st1102 motor to instal in my pool… when I took the old one out a washer and slinger came out of the shaft, the washer was terribly corroted and the slinger had a tear (they need to be replaced).

Can you please direct me to the proper parts so I can purchase them (attached is a picture of the ones that came out as reference).

Also, I have watched a bunch of videos on how to instal this motor and in none of them they use or make reference to either a washer or a slinger… could you please also explain to me where this washer and slinger should go so I instal this motor properly.

Thanks for your help!
