4AD Water Pump Rebuild Kit

Post by ucantucan »

I'm almost finished with the engine rebuild but upon startup the water pump was leaking. I ordered a rebuild kit from Trevor and found that the ceramic face seal was larger than the origninal. I assumed that I needed to spot face the surface to match the new seal. Also the spring and rubber gizmo was different. Once again my assumption was that the metal cup holding the "gizmo" together should be pressed into the recess in the brass rotor. I assembled all of this and started up the engine only to find the pump still leaking but to a much greater extent than before! What did I do wrong? Or, will the new seal wear itself in? Help
