Chrysler Le Baron, Dodge Dynasty, Plymouth Acclaim. Manual - part 119

Remove old sealant before applying new seal-

ant. Use MOPAR

t Adhesive Sealant on retainer

to seal retainer to case.

BEARING ADJUSTMENT PROCEDURES

GENERAL RULES ON SERVICING BEARINGS

(1) Take extreme care when removing and in stalling

bearing cups and cones. Use only an arbor press for
installation, as a hammer may not properly align the
bearing cup or cone. Burrs or nicks on the bearing seat
will give a false end play reading, while gauging for
proper shims. Improperly seated bearing cup and cones
are subject to low-mileage failure.

(2) Bearing cups and cones should be replaced if they

show signs of pitting or heat distress.

If distress is seen on either the cup or bearing rollers,

both cup and cone must be replaced.

Bearing end play and drag torque specifica-

tions must be maintained to avoid premature
bearing failures.

Used (original) bearing may lose up to 50 of the

original drag torque after break-in.

All bearing adjustments must be made with no

other component interference or gear inter-
mesh, except the transfer gear bearing.

OUTPUT SHAFT BEARING

With output shaft gear removed.
(1) Install a 13.65 mm (.537 inch) and a 1.34 mm

(.053 inch) gauging shims on the planetary rear annu-
lus gear hub using grease to hold the shims in place.
The 13.65 mm shim has a larger inside diameter and
must be installed over the output shaft first. The 1.34
mm shim pilots on the output shaft.

(2) Install output shaft gear and bearing assembly,

torque to 271 N

Im (200 ft. lbs.).

(3) To measure bearing end play:

(a) Attach Tool L-4432 to the output shaft gear.
(b) Mount a steel ball with grease into the end of

the output shaft.

forth to insure seating of the bearing rollers.

(d) Using a dial indicator, mounted to the tran-

saxle case, measure output shaft end play.
(4) Once bearing end play has been determined,

refer to the output shaft bearing shim chart for the
required shim combination to obtain proper bearing
setting.

(a) The 12.65 mm (.498 inch), 13.15 mm (.518 inch)

or 13.65 mm (.537 inch) shims are always in-

stalled first. These shims have lubrication slots
which are necessary for proper bearing lubri-
cation.

(b) Shims thinner than 12.65 mm listed in the

chart are common to both the transfer shaft and
output shaft bearings.
(5) Use Tool L-4424 to remove the retaining nut and

washer. To remove the output shaft gear use Tool
L-4407.

(6) Remove the two gauging shims and install the

proper shim combination, making sure to install the
12.65, 13.15, or 13.65 mm shim first. Use grease to hold
the shims in place. Install the output shaft gear and
bearing assembly.

(7) Install the retaining nut and washer and torque

to 271 N

Im (200 ft. lbs.).

(8) Using an inch-pound torque wrench, check the

turning torque. The torque should be between 3
and 8 inch-pounds.

If the turning torque is too high, install a .05mm

(.002 inch) thicker shim. If the turning torque is too
low, install a .05 mm (.002 inch) thinner shim. Repeat
until the proper turning torque is 3 to 8 inch pounds.

DIFFERENTIAL BEARING

(1) Remove the bearing cup from the differential

bearing retainer using Tool L-4518, and remove the
existing shim from under the cup.

(2) Install a .50 mm (.020 inch) gauging shim and

reinstall the bearing cup into the retainer. Use an
arbor press to install the cup.

Oil Baffle is not required when making shim

selection.

(3) Install the bearing retainer into the case and

torque bolts to 28 N

Im (250 in. lbs.).

(4) Position the transaxle assembly vertically on the

support stand and install Tool L-4436 into the exten-
sion.

(5) Rotate the differential at least one full revolution

to ensure the tapered roller bearings are fully seated.

(6) Attach a dial indicator to the case and zero the

dial indicator. Place the indicator tip on the end of Tool
L-4436.

(7) Place a large screwdriver to each side of the ring

gear and lift. Check the dial indicator for the amount of
end play.

CAUTION: Do not damage the transaxle case and/or
differential cover sealing surface.

(8) When the end play has been determined, refer to

the Differential Bearing Shim Chart for the correct
shim combination to obtain the proper bearing setting.

(9) Remove the differential bearing retainer. Re-

move the bearing cup and the .50 mm (.020 inch)
gauging shim.

(10) Install the proper shim combination under the

bearing cup. Make sure the oil baffle is installed
properly in the bearing retainer, below the bearing
shim and cup.

(11) Install the differential bearing retainer. Seal

the retainer to the housing with MOPAR

t Adhesive

Sealant and torque bolts to 28 N

Im (250 in. lbs.).

(12) Using special Tool L-4436 and an inch-pound

torque wrench, check the turning torque of the differ-
ential. The turning torque should be between 5
and 18 inch-pounds.

If the turning torque is too high, install a .05

mm (.002 inch) thinner shim. If the turning
torque is too low, install a .05 mm (.002 inch)
thicker shim. Repeat until 5 to 18 inch-pounds
turning torque is obtained.

TRANSFER SHAFT BEARING

(1) Use Tool L-4434 to remove the retaining nut and

washer. Remove the transfer shaft gear using Tool
L-4407.

(2) Install a 2.29 mm (.090 inch) and a 1.39 mm (.055

inch) gauging shims on the transfer shaft behind the
governor support.

TRANSAXLE

(3) Install transfer shaft gear and bearing assem-

bly and torque the nut to 271 N

Im (200 ft. lbs.).

(4) To measure bearing end play:

(a) Attach Tool L-4432 to the transfer gear.
(b) Mount a steel ball with grease into the end of

the transfer shaft.

and forth to insure seating of the bearing rollers.

(d) Using a dial indicator, measure transfer shaft

end play.
(5) Refer to the Transfer Bearing Shim Chart for

the required shim combination to obtain the proper
bearing setting.

(6) Use Tool L-4424 to remove the retaining nut

and washer. Remove the transfer shaft gear using
Tool L-4407.

(7) Remove the two gauging shims and install the

correct shim combination. Install the transfer gear and
bearing assembly.

(8) Install the retaining nut and washer and torque

to 271 N

Im (200 ft. lbs.). Measure transfer shaft end

play, end play should be .05 to .25 mm (.002 to .010
inch).

(9) Measure bearing end play as outlined in Step (4).

End play should be between .05 mm and .25 mm (.002
to .010 inch).

If end play is too high, install a .05 mm (.002

inch) thinner shim combination. If end play is
too low, install a .05 mm (.002 inch) thicker shim
combination. Repeat until .05 to .25 mm (.002 to
.010 inch) end play is obtained.
