Water Pump Question

I still use the Hyatt type front bearing since it has a longer history of relatively reliable service. The bushing with the rubber seal still has a packing in case the seal craps out so a person can limp a while before going back into the pump. I do use the adjustable thrust sleeve on the front to prevent the shaft from futher wearing on the stub inside the cylinder head. It seams to keep the shaft in check pretty well.

So far, no source offers a carbon face seal on the wet side to eliminate the packing. This would be the most reliable type but it just hasn't happened yet. Maybe some day!

A new water pump, which looks original and features a Carbon/Ceramic face seal, will soon be available. I will post more details in the thread titled "I need a job".

The new water pump uses 3 deep groove ball bearings that are sealed for life, and the same face seal that is used in Ford 2.3 (140), 2.5 (153), 3.0 (183), 3.3 (200), 3.8 (231), 4.1 (250), 4.2 (255), 5.0(302), 5.8 (351), 6.6 (400), and 7.5 (460) engines. This face seal is also used in water pumps for American Motors, General Motors, and Chrysler engines.
