[Tigers] water pumps and hubs

[Sandy Ganz]

Jerry -

I think that's the pump (#8842) I have as well. When Tim was working
on it he got a bronze bushing from McMaster Carr for the .625" to 1" shaft
size change. And as others have said measure measures measure. I pushed the
flange a bit far back on the initial try but figured out how to move it
forward after over use of the the press. Also one other tip make sure you have
the pump housing and all gaskets set up to get it aligned just right all that
crap adds up a bit. I have a set of Dale's pullys and don't think I have any
bolt issues (yet).

Ray,

I used the Edelbrock #8842 water pump on
my 302 and did press the hub back
further.  It's been 9 years ago and I can't
remember just how far I pressed
it back, but it can be done. That pump and
other newer ones have a stepped
shaft where the tip of the shaft is the same
size as the older ones (.625)
however about .550 inch back the shaft enlarges
up to .747 this is to
facilitate a larger bearing inside the pump (a good
thing). If you are
carful you can press the hub back just far enough that you
get alignment
with the engine pulley.  One thing to watch is the water pump
pulley
becoming close to one of the bolts on the water pump, the one that's
about
at the ten o'clock position (viewed from the front) mine is about .300
of an
inch clearance. Also if you are using the original water pump pulley
that
has the one inch center hole you might consider using the various ways
people have discussed of making an adapter that will take up the space
between
the one inch hole in the pulley and the .625 shaft. 

What I did was to
machine .050 off the face of the hub down to and leaving a
one inch diameter
protrusion that the pulley will index on, the pulley is
approx. .100 thick (if
I remember) this way you are assured that when you
tighten it all up the
pulley isn't high centering. It would be very easy to
just use the bolts to do
the centering, but that wouldn't necessarily
guarantee the pulley would run
true.

Measure, measure, measure and machine once. ;)

hello all,B 

a quick question
regarding water pumps on the 302 option.
can you press a hub further down on
the hd aftermarket pumps to use it on
the
tiger with a 302?B  or do i need to
press off the hub on my 260 type pump
and
put it on the new pump?

seems like
the mustangs used a body to hub measurement of 5.7".....but the
tigger is
different.

i used the old 260 pump for years, but it really is out of it's
depth with a
larger engine what with the open impellor and all.

thanks,

rayB
