Dodge Dakota (R1). Manual — part 678
(6) Slide clutch drum forward and install inner
retaining ring (Fig. 163).
(7) Install rear bearing and snap ring on output
shaft (Fig. 164). Be sure locating ring groove in bear-
ing is toward rear.
(8) Install overrunning clutch on hub (Fig. 165).
Note that clutch only fits one way. Shoulder on clutch
should seat in small recess at edge of hub.
(9) Install thrust bearing on overrunning clutch
hub. Use generous amount of petroleum jelly to hold
bearing in place for installation. Bearing fits one way
only. Be sure bearing is seated squarely against hub.
Reinstall bearing if it does not seat squarely.
(10) Install overrunning clutch in output shaft
(Fig. 166). Insert snap ring pliers in hub splines.
Expand pliers to grip hub. Then install assembly
with counterclockwise, twisting motion.
(11) Install planetary gear in annulus gear (Fig.
167). Be sure planetary pinions are fully seated in
annulus gear before proceeding.
(12) Coat planetary thrust bearing and bearing
contact surface of spring plate with generous amount
of petroleum jelly. This will help hold bearing in
place during installation.
(13) Install planetary thrust bearing on sun gear
(Fig. 168). Slide bearing onto gear and seat it against
spring plate as shown. Bearing fits one way only. If it
does not seat squarely against spring plate, remove
and reposition bearing.
(14) Install assembled sun gear, spring plate and
thrust bearing (Fig. 169). Be sure sun gear and
thrust bearing are fully seated before proceeding.
(15) Mount assembled output shaft, annulus gear,
and clutch drum in shop press. Direct clutch spring,
hub and clutch pack are easier to install with assem-
bly mounted in press.

(17) Install direct clutch spring (Fig. 171). Be sure
spring is properly seated on spring plate.
NOTE: The direct clutch in a 46RE transmission
uses 8 clutch discs.
(18) Assemble and install direct clutch pack on
hub as follows:
(a) Assemble clutch pack components (Fig. 172).
(b) Install direct clutch reaction plate on clutch
hub first. Note that one side of reaction plate is
counterbored. Be sure this side faces rearward.
Splines at rear of hub are raised slightly. Counter-
bore in plate fits over raised splines. Plate should
be flush with this end of hub (Fig. 173).
(c) Install first clutch disc followed by a steel
plate until all discs and plates have been installed.
(d) Install pressure plate. This is last clutch
pack item to be installed. Be sure plate is installed
with shoulder side facing upward (Fig. 174).
(19) Install clutch hub and clutch pack on direct
clutch spring (Fig. 175). Be sure hub is started on
sun gear splines before proceeding.
WARNING:
THE
NEXT
STEP
IN
GEARTRAIN
ASSEMBLY INVOLVES COMPRESSING THE DIRECT
CLUTCH HUB AND SPRING. IT IS EXTREMELY
IMPORTANT THAT PROPER EQUIPMENT BE USED
TO COMPRESS THE SPRING AS SPRING FORCE IS
APPROXIMATELY 830 POUNDS. USE COMPRES-
SOR TOOL C-6227-1 AND A HYDRAULIC-TYPE
SHOP PRESS WITH A MINIMUM RAM TRAVEL OF 6
INCHES. THE PRESS MUST ALSO HAVE A BED
THAT CAN BE ADJUSTED UP OR DOWN AS
REQUIRED. RELEASE CLUTCH SPRING TENSION
SLOWLY AND COMPLETELY TO AVOID PERSONAL
INJURY.
