The Tiger 260 Alum water pump is a standard Ford alum water pump which
fits any Fairlane , Falcon or Mustang 260 or 5 bolt 289, but has
these changes.
1. The front hub, where the fan mounts, is a 59 Mercury part with a 1
inch diameter center that fits the original four blade fan with a 1
inch diameter center hole.
C4JE - 8501 - A water pump
B9ME - 8553 - A hub
C4JZ - 8600 - B Fan
Do you still have the original water pump, hub, and fan for a Tiger?
2. The distance from the pump face to the hub is Tiger specific. See
the Shop Manual then check your pump. Please note the numbers for
this distance are NOT correct in the Manual, so check your pump.
Also check that when the pump is on the engine that the fan belt is
straight between all the pulleys. This is another indication that
you have the original parts or at least the right distance.
Distance in the Manual 260 5.15" 289 5.43"
Correct Numbers 4.875" 5.1"
The source of the correct numbers is "The Sunbeam Survivor" from TE/AE.
As far as I know the alum and cast iron pumps are not interchangeable.
You can upgrade your water pump with the Ford Motorsport water
impeller, M - 8512 - A302, but you need machine shop work and welding
to accomplish this. The Motorsport impeller reduces cavitation and
should reduce water temperature of the Tiger by 5 to 10 degrees.
Here is a brief description of how to install the Motorsport impeller.
First disassemble the water pump and measure the length of the original
water impeller.
The Motorsport water impeller snout is shorter than the original, cut
the snout off the original impeller longer than needed, machine cut
end flat and square, weld snout to the Motorsport impeller, machine to
correct length, check rotating balance of this new assembly.
If you do not have the original hub for the water pump, machine the
hub you have for the 1 inch diameter needed for the original fan. If
you do not have the original fan you may have to machine the hub to
obtain the correct distance for the hub to the impeller.
Assembly the water pump with new seals and bearing, set the correct
distance of the pump face to the hub. Dry check the pump on the
engine with the pulley to make sure all the pulleys are aligned.
