OPERATION
No.
ID
231-O
: AZignment of pulleys
ID
19
NOTE
- For
this
operation
the
water
pump
and
dynamo
driving
belt
must
be
removed
(see
Op.ID
231-4).
Use
fixture
1683-T
(see
Pl.
58).
Place
the
gauge
pin
bracket
(B)
in
position
with
the
face
marked
2 pulleys
towards
the
front
and
fix
the
bracket
on the
boss
provided
for
attachment
of the
high
pressure
pump
on
the
DS
19
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Place
rod
(A)
in
position
with
the
ball
end
resting
on
the
side
faces
of the
groove
of the
pulley
to be
aligned
(see
fig.
3),
and
with
the
rod
resting
on
one
of
the
gauge
pins
(C)
in
the
area
"f"
or
"g".
NOTE
- When
the
rod
engages
at
"g"
use
a set
of
feeler
gauges
to
make
sure
that
there
is
clearance
between
the
gauge
pin
and
the
rod.
This
clearance
must
be
0.45
f
0.25
mm
in
zone
"f"
if
the
pulley
is
properly
aligned.
Adjustment
of
the
water
pump
pulley
1st. case:
When
the
rod
bears
on
"f".
Reduce
the
thickness
of
the
adjusting
washers
of
the
pulley
by
three
times
the
amount
of the
clearance
"d"
measured
at
"g"
plus
0.45
x 2 = 0.90
mm
in
order
to
obtain
a clearance
at
'If"
of
0.45
f
0.25
mm.
The
pulley
is
then
correctly
adjusted.
Example
1 - Clearance
"d"
measured
at
"g"
= 0.3
mm.
The
thickness
of the
adjusting
washers
of the
pulley
must
be
reduced
by:
(0.3
x 3) t (0.45
x 2)
= 0.90
t
0.90
= 1.80
mm
2nd. case:
When
the
rod
bears
on
"g".
If the
clearance
"d"
measured
at
'If"
is
greater
than
0.45
f
0.25,
the
thickness
of
the
pulley
adjusting
washers
must
be
increased
by
twice
the
difference
between
the
clearance
measured
and
0.45
mm.
Example
2 - Clearance
"d"
measured
at
"f'l
= 0.80
mm.
The
thickness
of
the
pulley
adjusting
washers
must
be
increased
by:
(0.80
- 0.45)
x 2 = 0.70
mm.
3rd. case:
.4
If
the
clearance"'
d"
measured
at
'If"
is
less
than
0.45
f
0.25
mm,
the
thickness
of
the
pulley
adjusting
washers
must
be
decreased
by
twice
the
difference
between
0.45
mm
and
the
measured
distance.
Example
3 - Clearance
"d"
measured
at
"f"
= 0.25
mm.
The
thickness
of the
pulley
adjusting
washers
must
be
decreased
by:
(0.45
- 0.25)
x 2 = 0.20
x 2 = 0.40
mm.
Adjustment
of the
dynamo
pulley
(cars delivered since May
19.59).
NOTE
- When
the
rod
bears
on
"it',
the
clearance
"d"
must
be
0.225
f 0.05
mm
in
the
region
"h"
if the
pulley
is
aligned
correctly.
1st. case:
When
the
rod
bears
on "h"
.
Reduce
the
thickness
of the
pulley
adjusting
washers
by
five
times
the
clearance
"d"
measured
at
"i",
plus
0.225
x 4 = 0.90
mm,
to
obtain
at
"h"
a clearance
of
0.225
f
0.05
mm.
The
pulley
is
then
correctly
adjusted.
