Speedway Motors 1949-1953 Ford Flathead Engine Water Pump, Wide Belt Pulley
Original Flatheadhead 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 3/4" shaft, making the assembly exceptionally strong and more efficient.
- Includes both drivers side and passenger side pumps
- For Wide Belt Application, Gaskets Included
- Belt Width: 0.63"
- Mounted Length: 4.75"
- Heater Outlet Size: 3/8" NPT
- Overall Length: 5.38"
- Overall Height: 9.00"
- Designed for use with 5/8" belt drive system
- Severe-duty roller and ball bearings
- Ceramic seals on sturdy 3/4" shaft
- High-flow modular impeller reduces cavitation
- Includes gasket and a connection for the heater hose return
- Application
- Used when swapping the 1949-1953 engine into 1932-1948 Ford and Mercury cars and trucks

49-53 truck water pump set
Fitting an 8BA in a 1933 model BB truck. Need this style pumps to mount to early frame. Stock engine mounts with 3.5 inch risers to clear crank pulleys. Tight fit, but it goes in.

Good product, but…
…these pumps will bolt up to a 49-51 Mercury flathead but will not line up with the motor mounts. If you have a stock 49-51 Mercury you will have to rebuild your original pumps or try to track down some good used ones.

Water pumps seemed like quality parts right out of the box, were instrumental in cooling down the F-5 flathead and the fact that they came painted already was a bonus.
