This
table
is
copied
directly
from
the
ProSteering
application
guide

In
this
example,
the
gear
type
for
this
customer’s
vehicle
should
be
a
TRW
gear
type.

Our
application
guide
information
does
not
show
any
history
of
a
Sheppard
type
gear

being
used
on
this
application.

Step
1:

Ask
the
customer
to
verify
he
has
a
TRW
type
unit
and
verify
the
gear
spec

number.

Step
2:

If
the
customer
is
unable
to
identify
the
characters
on
the
ID
pad
to
confirm

his
unit
is
a
TAS40006
or
TAS55001
ask
for
the
gear
housing
casting
number.

Step
3:

In
this
example,
our
customer
has
a
gear
with
the
casting
number
=

TAS552299
which
cross
references
to
PSG
part
number
55001R

Step
4:

Whenever
we
identify
a
gear
with
a
method
other
than
the
gear
spec

(characters
pin
stamped
on
the
gear)
it
is
a
good
idea
to
verify
the
housing
casting,
#

of
lines,
relief
valve
option,
#
of
frame
mounting
pads,
and
input
shaft
configuration.

Information
about
the
frame
mounting
pads
and
input
shaft
configuration
are

included
in
our
product
catalog
or
on
our
website.

A. In
this
example
the
gear
housing
number
is
TAS552299
leading
us
to
believe

the
PSG
part
number
is
55001R

B. Verify
with
our
customer
they
have
a
power
steering
gear
with
2
lines
(one

pressure
line
and
one
return
line)
and
their
gear
is
equipped
with
a
relief
valve.

C. Use
the
online
catalog
information
to
confirm
the
remaining
features
of
this

steering
gear
which
include:

a. Notch
and
Flat
input
shaft
configuration

b. 3
frame
mounting
pads
