It is called out in the parts diagram for the CP 0077 Sludge Pump. Check it against the reference number on the diagram first; serial breaks change what fits.
The parts diagram library indexes every breakdown we publish, and the CP tool catalog has the tools these parts go into. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
