Shaft Seal Replacement

I need to replace the shaft seal as there is visable water leaking from the motor.  I have the model # of the pump but don’t know if it’s pre-1998. Please advise.

model # P2R 5d-124L

I think it is a Sta-Rite pump

That is a Dura-Glas model number. The Pre-1998 models have a copper cone in the seal plate. You can get the 1998 and after kit and if there is a copper cone, remove it. The new style seal will fit once the cone is removed. The newer seal kit is part number GOKIT54. Click Here to View the New Sta-Rite Dura-Glas Seal Kit - GOKIT54
