COLUMN SHIFT

The manual lever assembly
on ve-

hicles equipped with
a
column shift
in-

corporates
an oil
impregnated plastic

grommet
in the end of the
lever
arm.

A special tool T67P-7341-A
is re-

quired
to
install
the
grommet
in the

manual lever,
and to
install
the
manu-

al linkage
rod
into
the
grommet.
Re-

move
and
install
the
grommet
as fol-

lows:

1.
Place
the
lower
jaw of the
tool

between
the
manual lever
and the con-

trol
rod.
Position
the
stop
pin
against
the
end of the
control
rod (Fig. 18)

and force
the rod out of the
grommet.

Remove
the
grommet from
the
manu-

al lever
by
cutting
off the
large shoul-

der with
a
sharp knife.
The
grommet

must
be
removed from
the
manual

lever
and a new one
installed each

time
the rod is
disconnected.

2.
Before installing
a
new grommet,

adjust
the
stop
pin to 1/2
inch
and

coat
the
outside
of the
grommet with

lubricant. Then, place
the
grommet
on

the stop
pin and
force
it
into
the
man-

ual lever hole. Turn
the
grommet
sev-

eral times
to be
sure
it is
properly

seated.

3.
Readjust
the
stop
pin to the
height shown
in Fig. 18. The pin

height
is
determined
by the
length
of

the
rod end
which
is to be
installed

into
the
grommet.
If the pin
height
is

not adjusted,
the
control
rod may be

pushed
too far
through
the

re-

taining
lip.

4.
With
the pin
height properly
ad-

justed, position
the
control
rod on the

tool
and

lip of the
grom-

met.
Be
sure
the rod
protrudes

through
the
grommet approximately

1/4 inch after installation.

INTERFERENCE CHECK

1.
Position
the
front pump assem-

bly
on a
bench with
the
spline
end of

the stator shaft pointing
up
(Fig.

and the

converter
hub
engages
the
pump drive

gear.

3.
While holding
the
pump station-

ary, try
to
rotate the converter counter-

clockwise.
The
converter should
ro-

tate freely without
any
signs
of
inter-

ference
or
scraping within
the
convert-

er assembly.
4.
If
there
is an
indication
of
scrap-

ing,
the
trailing edges
of the
stator

blades
may be
interfering with
the

leading edges
of the
impeller blades.

In such cases, replace
the
converter.

STATOR
TO
TURBINE

INTERFERENCE CHECK

1.
Position
the
converter
on the

bench front side down.

2.

interference
or
scraping

noise.

5.
If
interference exists,
the
stator

front thrust washer
may be
worn,
al-

lowing
the
stator
to hit the
turbine.
In

such cases,
the
converter must
be re-

placed.

The converter crankshaft pilot

should
be
checked
for
nicks
or dam-

aged surfaces that could cause inter-

ference when installing
the
converter

into
the
crankshaft. Check
the con-

verter front pump drive
hub for
nicks

or sharp edges that would damage
the

pump seal.
