How is the seal plate removed from motor

A  Answered on 9/20/2018 by InyoPools Product Specialist Hector F.

You would need to first remove the impeller which if you click here you can view a general guide for that and then remove the 4 bolts that hold the motor to the seal plate.

I have a PAC-FAB Challenger 21/2 HP pump. It says CFI-N2-21/2AH, 2-05-I91, 34-4049 on the label on the pump. Is this the right replacement part? I have replaced the shaft seal twice and it still leaks a little while it is running so I figured it would be good to replace this part also. Any help would be appreciated.

Hi, Larry. This is the correct replacement seal plate for your model pump.
