FRONT AXLE - 186FIA
DESCRIPTION
The 186FIA (Model 30) axle consists of an alumu-
num center section with an axle tube extending from
one side. The tube is pressed into the differential
housing. The integral type housing, hypoid gear
design has the centerline of the pinion set below the
centerline of the ring gear.
The differential case is a one-piece design. The differ-
ential pinion mate shaft is retained with a roll-pin. Dif-
ferential bearing preload and ring gear backlash is
adjusted by the use of shims (select thickness). The
shims are located between the differential bearing cups
and the axle housing. Pinion bearing preload is set and
maintained by the use of a collapsible spacer.
The power is transferred from the axle through two
constant velocity (C/V) drive shafts to the wheel hubs.
The differential cover provides a means for inspec-
tion and service without removing the axle from the
vehicle. The cover has a vent tube used to relieve
internal pressure caused by vaporization and inter-
nal expansion.
OPERATION
The axle receives power from the transfer case through
the front propeller shaft. The front propeller shaft is con-
nected to the pinion gear which rotates the differential
through the gear mesh with the ring gear bolted to thedifferential case. The engine power is transmitted to the
axle shafts through the pinion mate and side gears. The
side gears are splined to the axle shafts.
During straight-ahead driving, the differential pin-
ion gears do not rotate on the pinion mate shaft. This
occurs because input torque applied to the gears is
divided and distributed equally between the two side
gears. As a result, the pinion gears revolve with the
pinion mate shaft but do not rotate around it (Fig. 1).

PINION DEPTH MEASUREMENT
Measurements are taken with pinion bearing cups
and pinion bearings installed in the housing. Take
measurements with Pinion Gauge Set and Dial Indi-
cator C-3339 (Fig. 10).
(1) Assemble Pinion Height Block 6739, Pinion
Block 8804 and rear pinion bearing onto Screw 6741
(Fig. 10).
(2) Insert height gauge components into the hous-
ing through pinion bearing cups.
(3) Install front pinion bearing and hand tight
Cone-nut 6740 onto the screw.
(4) Position Arbor Disc 6732 and Arbor D-115-3
into the housing bearing cradles. Install differential
bearing caps on Arbor Discs and tighten bolts to 41
N´m (30 ft. lbs.) (Fig. 11).
NOTE: Arbor Discs 6732 has different step diame-
ters to fit other axles. Choose proper step for axle
being serviced.
(5) Assemble Dial Indicator C-3339 into Scooter
Block D-115-2 and secure set screw.(6) Position Scooter Block/Dial Indicator flush on
the pinion height block. Hold the scooter block and
zero the dial indicator.
(7) Slowly slide the scooter block across the pinion
height block over to the arbor (Fig. 12). Move the
scooter block till the dial indicator probe crests the
arbor and record the highest reading.
(8) Select a shim/oil slinger equal to the dial indi-
cator reading plus the pinion depth variance number
etched in the face of the pinion (Fig. 8). For example,
if the depth variance is ±2, add +0.002 in. to the dial
indicator reading.
DIFFERENTIAL
Differential bearing preload and gear backlash is
adjusted by the use of selective shims. The shims are
located between the differential bearing cups and the
differential housing. The proper shim thickness can
be determined using slip-fit Dummy Bearings D-348
in place of the differential side bearings and a Dial
Indicator C-3339. Before proceeding with the differ-
ential bearing preload and gear backlash measure-
ments, measure the pinion gear depth and prepare
the pinion for installation. Establishing proper pinion
gear depth is essential to establishing gear backlash
and tooth contact patterns. After the overall shim
thickness to take up differential side play is mea-
sured, the pinion is installed, and the gear backlash

(11) Push and hold differential case to ring gear
side of the housing and record dial indicator reading
(Fig. 19).
(12) Add 0.152 mm (0.006 in.) to the zero end play
total. This new total represents the thickness of
shims to compress or preload the new bearings when
the differential is installed.
(13) Rotate dial indicator out of the way on the
pilot stud.
(14) Remove differential case and dummy bearings
from the housing.
(15) Install the pinion gear in the housing. Install
the pinion yoke and establish the correct pinion
rotating torque.
(16) Install differential case and Dummy Bearings
D-348 in the housing.
(17) Install a single dummy shim in the ring gear
side. Install bearing caps and tighten bolts snug.
(18) Seat ring gear side dummy bearing (Fig. 17).
(19) Position the dial indicator plunger on a flat
surface between the ring gear bolt heads.
(20) Push and hold differential case toward pinion
gear and zero dial indicator (Fig. 20).
(21) Push and hold differential case to ring gear
side of the housing and record dial indicator reading
(Fig. 21). Add dummy shim thickness to this reading.
This will be the total shim thickness to achieve zero
backlash.
(22) Subtract 0.076 mm (0.003 in.) from the dial
indicator reading to compensate for backlash between
ring and pinion gears. This total is the thickness
shim required to achieve proper backlash.
(23) Subtract the backlash shim thickness from
the total preload shim thickness. The remainder is
the shim thickness required on the pinion side of the
axle housing.(24) Rotate dial indicator out of the way on pilot
stud.
(25) Remove differential case and dummy bearings
from the housing.
(26) Install side bearings and cups on differential
case.
(27) Install spreader W-129-B with Adapter Set
6987 on the housing and spread axle opening enough
to receive differential case.
CAUTION: Never spread the differential housing
over 0.34 mm (0.013 in.). If the housing is over-
spread, it could be distorted or damaged.

REAR AXLE - 198RBI
DESCRIPTION
The Rear Beam-design Iron (RBI) axle housing has
an iron center casting (differential housing) with axle
shaft tubes extending from either side. The tubes are
pressed into and welded to the differential housing to
form a one-piece axle housing. The axles are
equipped with semi±floating axle shafts, meaning
that loads are supported by the axle shaft and bear-
ings. The axle shafts are retained by the unit bear-
ing, retainer plate and bolts.
The integral type, hypoid gear design, housing has
the centerline of the pinion set below the centerline
of the ring gear. The differential case is a one-piece
design. The differential pinion mate shaft is retained
with a threaded screw. Differential bearing preload
and ring gear backlash is adjusted by the use of
selective spacer shims. Pinion bearing preload is set
and maintained by the use of a collapsible spacer
(Fig. 1).
The cover provides a means for servicing the differ-
ential without removing the axle. The axle has a vent
hose to relieve internal pressure caused by lubricant
vaporization and internal expansion.
Axles equipped with a Trac-Loktdifferential are
optional. A Trac-Loktdifferential has a one-piece dif-ferential case, and the same internal components as
a standard differential, plus two clutch disc packs.
OPERATION
The axle receives power from the transmission/
transfer case through the rear propeller shaft. The

(6) Position Scooter Block/Dial Indicator flush on
the pinion height block. Hold scooter block and zero
the dial indicator.
(7) Slowly slide the scooter block across the pinion
height block over to the arbor (Fig. 14). Move the
scooter block till the dial indicator probe crests the
arbor bar and record the highest reading. If the dial
indicator can not achieve the zero reading, the rear
bearing cup or the pinion depth gauge set is not
installed correctly.
(8) Select a shim equal to the dial indicator read-
ing plus the drive pinion gear depth variance number
etched in the face of the pinion gear (Fig. 9) using
the opposite sign on the variance number. For exam-
ple, if the depth variance is ±2, add +0.002 in. to the
dial indicator reading.
(9) Remove the pinion depth gauge components
from the housing
DIFFERENTIAL BEARING PRELOAD
Differential side bearing preload and gear backlash
is achieved by selective shims inserted between the
bearing cup and the housing. The proper shim thick-
ness can be determined using slip-fit Dummy Bear-
ings D-348 in place of the differential side bearings
and a Dial Indicator C-3339. Before proceeding with
the differential bearing preload and gear backlash
measurements, measure the pinion gear depth and
prepare the pinion gear for installation. Establishing
proper pinion gear depth is essential to establishing
gear backlash and tooth contact patterns. After the
overall shim thickness to take up differential sideplay is measured, the pinion gear is installed and the
gear backlash shim thickness is measured. The over-
all shim thickness is the total of the dial indicator
reading, starting point shim thickness and the pre-
load specification added together. The gear backlash
measurement determines the thickness of the shim
used on the ring gear side of the differential case.
Subtract the gear backlash shim thickness from the
total overall shim thickness and select that amount
for the pinion gear side of the differential (Fig. 15).

rear propeller shaft is connected to the pinion gear
which rotates the differential through the gear mesh
with the ring gear bolted to the differential case. The
engine power is transmitted to the axle shafts

SIDE GEAR CLEARANCE
NOTE: When measuring side gear clearance, check
each gear independently. If it necessary to replace a
side gear, replace both gears as a matched set.
(1) Install the axle shafts, C-locks and pinion mate
shaft.
(2) Measure each side gear clearance. Insert a
matched pair of feeler gauge blades between the gear
and differential housing on opposite sides of the hub
(Fig. 17).
(3) If side gear clearances is no more than 0.005
inch. Determine if the axle shaft is contacting the
pinion mate shaft.Do not remove the feeler
gauges, inspect the axle shaft with the feeler
gauge inserted behind the side gear.If the end ofthe axle shaft is not contacting the pinion mate
shaft, the side gear clearance is acceptable.
(4) If clearance is more than 0.005 inch (axle shaft
not contacting mate shaft), record the side gear clear-
ance. Remove the thrust washer and measure its
thickness with a micrometer. Add the washer thick-
ness to the recorded side gear clearance. The sum of
gear clearance and washer thickness will determine
required thickness of replacement thrust washer
(Fig. 18).
In some cases, the end of the axle shaft will move
and contact the mate shaft when the feeler gauge is
inserted. The C-lock is preventing the side gear from
sliding on the axle shaft.
(5) If there is no side gear clearance, remove the
C-lock from the axle shaft. Use a micrometer to mea-
sure the thrust washer thickness. Record the thick-
ness and re-install the thrust washer. Assemble the
differential case without the C-lock installed and re-
measure the side gear clearance.
(6) Compare both clearance measurements. If the
difference is less than 0.012 inch (0.305 mm), add
clearance recorded when the C-lock was installed to
thrust washer thickness measured. The sum will
determine the required thickness of the replacement
thrust washer.
(7) If clearance is 0.012 inch (0.305 mm) or
greater, both side gears must be replaced (matched
set) and the clearance measurements repeated.
(8) If clearance (above) continues to be 0.012 inch
(0.305 mm) or greater, the case must be replaced.
