ADJUSTMENTS (Continued)
(3) Back off adjusting screw the number of turns
listed in Specifications. Hold adjusting screw in this
position and tighten locknut to 47 N·m (35ft. lbs.)
LOW/REVERSE BAND (REAR)
To adjust low-reverse band, proceed as follows:
(1) Loosen and back off locknut approximately 5
turns.
(2) Using an inch-pound torque wrench, tighten
adjusting screw to 5 N·m (41 in. lbs.) true torque.
(3) Back off adjusting screw the number of turns
listed under Specifications. This chart is located at
the rear of this section.
(4) Tighten locknut to 14 N·m (10 ft. lbs.).
HYDRAULIC CONTROL PRESSURE ADJUSTMENTS
LINE PRESSURE
An incorrect throttle pressure setting will cause
incorrect line pressure readings even though line
pressure adjustment is correct. Always inspect and
correct throttle pressure adjustment before adjusting
the line pressure.
The approximate adjustment for line pressure is
1-5/16 inches, measured from valve body to inner
edge of adjusting nut. However, due to manufactur-
ing tolerances, the adjustment can be varied to
obtain specified line pressure.
The adjusting screw may be turned with an Allen
wrench. One complete turn of adjusting screw
changes closed throttle line pressure approximately
1-2/3 psi. Turning adjusting screw counterclockwise
increases pressure, and clockwise decreases pressure.
THROTTLE PRESSURE
Throttle pressures cannot be tested accurately;
therefore, the adjustment should be measured if a
malfunction is evident.
(1) Insert gauge pin of Tool C-3763 between the
throttle lever cam and kickdown valve.
(2) By pushing in on tool, compress kickdown
valve against its spring so throttle valve is com-
pletely bottomed inside the valve body.
(3) While compressing spring, turn throttle lever
stop screw with adapter C-4553. Turn until head of
screw touches throttle lever tang, with throttle lever
cam touching tool and throttle valve bottomed. Be
sure adjustment is made with spring fully com-
pressed and valve bottomed in the valve body.
BEARING ADJUSTMENT PROCEDURES
(1) Take extreme care when removing and install-
ing 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-mile-
age failure.
(2) Bearing cups and cones should be replaced if
they show signs of pitting or heat distress.
(3) If distress is seen on either the cup or bearing
rollers, both cup and cone must be replaced.
NOTE: Bearing end play and drag torque specifica-
tions must be maintained to avoid premature bear-
ing failures.
(4) Used (original) bearing may lose up to 50 per-
cent of the original drag torque after break-in.
NOTE: All bearing adjustments must be made with
no other component interference or gear inter-
mesh, except the transfer gear bearing.
(5) Refer to the conversion chart in specifications
to convert inches to millimeter measurements. Refer
to bearing shim chart for proper shim thicknesses.
OUTPUT SHAFT BEARING
(1) With output shaft gear removed, install a 13.65
mm (.537 inch) and a 1.34 mm (.053 inch) gauging
shims on the planetary rear annulus 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·m (200 ft. lbs.).
(3) To measure bearing end play:
(4) Attach Tool L-4432 to the output shaft gear.
(5) Mount a steel ball with grease into the end of
the output shaft.
(6) Push and pull the gear while rotating back and
forth to insure seating of the bearing rollers.
(7) Using a dial indicator, mounted to the tran-
saxle case, measure output shaft end play.
(8) Once bearing end play has been determined,
refer to the output shaft bearing shim chart.
(9) The 12.65 mm (.498 inch), 13.15 mm (.518
inch) or 13.65 mm (.537 inch) shims are always
installed first. These shims have lubrication slots
which are necessary for proper bearing lubrica-
tion.
(10) Shims thinner than 12.65 mm listed in the
chart are common to both the transfer shaft and out-
put shaft bearings.
(11) Use Tool L-4434 to remove the retaining nut
and washer. To remove the output shaft gear use Tool
L-4407.
(12) 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
