Re: [ihc] A727 Transmissions and other Torqueflites

[Colin MM Rush <salmineo@xxxxxxxx>]

In IH product, there was only one TorqueFlite product used, and that was
the TorqueFlite A727.  That is the same 3-speed used behind most MoPars
with the Hemis and B/RB engines, and the same one in the Scout and the
pickups.  There was a heavier TorqueFlite that was made, called the
NP-345, which was a 4-speed variation on the 727 that was built
exclusively for special motor home chassis and the commercial 2 through 5
ton Dodge trucks in the early 1970s.  They are definitely up to the task.
 They had an underdrive extra-low first gear (something like 4:1), and an
output shaft that was about 2" thick.  They worked, but they are as rare
as hens' teeth.  I have been looking for one for two years now, and have
only found them at Transmission Exchange, where they are something like
$800 just for a rebuilder core.  Plus they only fit the Dodge B/RB bolt
pattern, so it would not fit an IHC motor without an adaptor plate.  If
you had to have a TorqueFlite, then you would want an A618 instead, which
is an overdrive 4-speed.  They are easier to find, and quite heavy duty,
else they would not come behind the Dodge Cummins diesels.  However, you
will still need to fab an adaptor plate, and they are not just a giveaway
item.  I would stick with the Allison.  They are a good unit, but due to
their application and newness, they will cost too.  If you want one, you
are going to have to bite the bullet, or give up on the whole idea.

Tom-
 
You need an industrial grade transmission. Keep looking for the Allison
or
other equivalent grade transmission. You'd be replacing the transmission
every 10,000 miles trying to move that bus around.
 
The Allison I have not only is much larger and heavier duty than the
torqueflight, it also has in-line filters, much like standard issue spin
on
filters from the engine, like the Wix 1452 used on SV series engines. The
same is true of the fuel line from the fuel tank.
 
My next major project appears to be putting a 304 in my school bus so I
can
drive it around instead of having to haul it. It should be a fun project,
altering the brackets for the power steering and air conditioning and all
that.
 
I wonder if anybody will want the fuel system from the diesel...
