SHOP MANUAL Paragraphs
6-7
gears
for
1700
and
1900 models should
be 0.05-0.10 mm (0.002-0.004 inch) with
a wear limit
of 0.45 mm
(0.018 inch).
'Renew thrust washers
(24 and 29)
and/or gears
if
backlash
is
excessive.
Diametral clearance between pinion
gears
(25) and
shaft
(26)
should
be
0.10-0.30 mm (0.004-0.012 inch).
Ring gear (22) and pinion (21) must be
renewed
as a
matched
set.
Cap screws
attaching ring gear
to
differential
car-
rier
(23)
should
be
tightened
to the
following torque: 30-34
N-m
(22-25
ft.-lbs.)
on
1100
and
1200 models; 30-40
N-m (22-30 ft.-lbs.)
on 1300
models;
60-70
N-m
(44-51 ft.-lbs.)
on 1500
models; 47-55
N-m
(35-40 ft.-lbs.)
on
1700 and 1900 models.
Install drive pinion (21) in center hous-
ing using shims (19) that were originally
installed
for
initial assembly.
To
adjust
pinion bearing preload, wrap
a
cord
around pinion shaft as shown in Fig.
10.
Use
a
spring scale
to
measure pull
re-
quired
to
rotate the shaft. Tighten inner
nut (15-Fig.
7,
8
or
9) until spring scale
reading is 5-6 kg
(11-13
pounds)
for
1100
and
1200
models; 5V2-7
kg
(12-13
pounds)
for
1300 and 1500 models; 11-15
kg (24V4-33 pounds)
for
1700
and 1900
models. Install washer (16)
and
tighten
outer
nut (15),
then recheck rolling
torque.
If differential carrier (23), cover (30),
carrier bearings
(31),
ring gear
and
drive pinion, center housing (34)
or
axle
shaft housings (43) were renewed,
dif-
ferential carrier bearing preload, ring
gear
to
pinion backlash
and
gear mesh
must
be
checked
and
adjusted
as out-
lined
in
paragraphs
6 and 7. If
none
of
these components
are
being renewed,
reassemble differential
and
front axle
installing original shims in their original
locations.
6. DIFFERENTAL CARRIER
BEARING PRELOAD.
To
adjust
car-
rier bearings, first attach right axle
housing to center housing (34-Fig.
7, 8
or 9). Place housing
in
vertical position
with center housing up. Assemble suffi-
cient thickness
of
shims (32)
in
housing
bore to make sure that ring gear will
not
contact drive pinion, then install
dif-
ferential assembly in center housing.
Be
sure that carrier bearing
is
properly
seated
in
axle housing bore.
Position left axle housing over
dif-
ferential assembly using more shims (33)
than will
be
required
to
ensure that
there
is
clearance between axle housing
and center housing. Install four equally
spaced bolts around axle housing
and
tighten finger tight. Use
a
feeler gage
to
measure gap between the two housings,
then remove left axle housing
and sub-
tract shims from shim pack (33) equal
to
the measured gap.

This will provide correct preload
for
differential carrier bearings. Adjust ring
gear
to
pinion backlash
as
outlined
in
paragraph
7,
7.
RING GEAR TO PINION BACK-
LASH. The backlash between ring gear
and pinion should
be
0.10-0.15
mm
(0.004-0.006 inch). With left axle hous-
ing removed, backlash
can be
checked
using
a
dial indicator
as
shown
in Fig.
11.
To adjust backlash, move shims (32)
from right axle housing
to
left axle
housing.
