It is called out in the parts diagram for the CP 0010 Centrifugal Pump. Check it against the reference number on the diagram first; serial breaks change what fits.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the parts breakdown index. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
