Note: After attaching
the center
support bearing, check and
make
certain the driveshaft
is
straight
and true. lt
is recommended
to
check
for
driveshaft straightness
before
final welding on the brack-
ets. One
suggested
method to
check
for
straightness
is
to tie
weighted strings
to the transmis-
sion extension
housing, center
bearing and differential compan-
ion flange, then visually
note
the
alignment
from the rear; make
certain all
the
strings
hang from
the exact centers of
the
three
locations.

The floor
pan
of the car must be
pounded
out
as shown
in the il-
lustration for
relief
around the
center bearing support.
E. Rear axle.
1. The
rear
axle should
be mounted
with the
length of the
lower
con-
trol
links set to 495
mm from cen-
ter-to-center of the
rod
ends, so
the
nose of the differential
is in-
clined upwards by
2", as shown
in the
illustration.

1. Pedal stroke.
The
pedal
stroke
should
be set at
130

mm, by adjusting
the
pedal
stroke stop

When
assembling
the clutch disc,
use either
the transmission
input
shaft
or a clutch alignment
tool
to align
the disc
properly.
The clutch
release
fork return
spring
should
be
mounted inside
a
rubber tube
to
prevent
the oc-
currence
of
resonant vibrations.
B. Transmlsslon.
1. Gear oil.
Generally,90
wt
gear
oil is
recom-
mended
for most conditions.
However,
if
the ambient
tempera-
ture is over 85o
F,
a
heavier
lubri-
cant should
be used.
2. Transmission
break-in.
While breaking
in
a
new transmis-
sion,
pay particular
attention
to
any
leaks, abnormal
sounds
or
unusual
vibrations. The
break-in
schedule
is
as shown
in
the
table.

C. Driveshaft.
The competition
driveshaft has
already
been
balanced
as a com-
plete
assembly. lf disassembling,
use
care
to re-assemble it in
the
correct order to maintain
its
bal-
ance.
Finally, the forward section
should
not be disassembled,
as
an unbalance
on that end could
lead
to
metal fatigue
and crack-
ing
of
the transmission extension
housing.
Make certain there
is
a
balance
weight on the driveshaft before
using
it.
Check
the
universal
joints
accord-
ing to the following
directions
and the
illustration
below.
(1)
The correct torque should be
3-B kg-cm
(with
a
new
joint).
(2)
To check
the forward univer-
sal
joint,
attach
the
sliding
scale to the
yoke.
