Details

Original Flathead water pumps have always suffered from unreliable bronze bushings and carbon seals. They almost always leaked and even Ford manuals warned mechanics not to tighten fan belts too tight. The excess slack allowed belts to slip and lose contact with the generator and water pump pulleys, causing more cooling and power problems.

Speedway's completely new water pumps feature severe-duty roller and ball bearings, close tolerances and modular impellers to provide maximum flow and reduce cavitation. They also have modern ceramic seals on a heavy duty 5/8" shaft, making the assembly exceptionally strong and more efficient. All mounting areas are spot faced for improved fit and sealing.

  • All-new high-nickel iron castings
  • Severe-duty roller and ball bearings
  • Ceramic seals on sturdy 3/4" shaft
  • High-flow modular impeller reduces cavitation
  • Gaskets included
  • For systems with 5/8" drive belts

Factory replacement for 1937-1948 Ford and Mercury cars and trucks. Includes gaskets.
