Chrysler RG Voyager. Manual — part 1080
OPERATION
The function of an accumulator is to cushion the
application of a frictional clutch element. When pres-
surized fluid is applied to a clutch circuit, the appli-
cation force is dampened by fluid collecting in the
respective accumulator chamber against the piston
and spring(s). The intended result is a smooth, firm
clutch application.
DRIVING CLUTCHES
DESCRIPTION
Three hydraulically applied input clutches are used
to drive planetary components. The underdrive, over-
drive, and reverse clutches are considered input
clutches and are contained within the input clutch
assembly (Fig. 167). The input clutch assembly also
contains:
• Input shaft
• Input hub
• Clutch retainer
• Underdrive piston
• Overdrive/reverse piston
• Overdrive hub
• Underdrive hub
OPERATION
The three input clutches are responsible for driving
different components of the planetary geartrain.
NOTE: Refer to the “Elements In Use” chart in Diag-
nosis and Testing for a collective view of which
clutch elements are applied at each position of the
selector lever.

ACCUMULATOR (Continued)
UNDERDRIVE CLUTCH
The underdrive clutch is hydraulically applied in
first, second, and third (direct) gears by pressurized
fluid against the underdrive piston. When the under-
drive clutch is applied, the underdrive hub drives the
rear sun gear.
OVERDRIVE CLUTCH
The overdrive clutch is hydraulically applied in
third (direct) and overdrive gears by pressurized fluid
against the overdrive/reverse piston. When the over-
drive clutch is applied, the overdrive hub drives the
front planet carrier.
REVERSE CLUTCH
The reverse clutch is hydraulically applied in
reverse gear only by pressurized fluid against the
overdrive/reverse piston. When the reverse clutch is
applied, the front sun gear assembly is driven.
FINAL DRIVE
DESCRIPTION
The 41TE differential is a conventional open
design. It consists of a ring gear and a differential
case. The differential case consists of pinion and side
gears, and a pinion shaft. The differential case is
supported in the transaxle by tapered roller bearings
(Fig. 168).
OPERATION
The differential assembly is driven by the transfer
shaft by way of the differential ring gear. The ring
gear drives the differential case, and the case drives
the driveshafts through the differential gears. The
differential pinion and side gears are supported in
the case by thrust washers and a pinion shaft. Dif-
ferential pinion and side gears make it possible for
front tires to rotate at different speeds while corner-
ing.
DISASSEMBLY
The transfer shaft should be removed for differen-
tial repair and bearing turning torque checking.
(1) Remove the differential cover and bolts (Fig.
169) (Fig. 170).

(2) Remove the differential bearing retainer and
bolts (Fig. 171) (Fig. 172).
(3) Using a plastic hammer, remove extension
housing/adapter plate on the right side of the trans-
axle.
WARNING: HOLD ONTO DIFFERENTIAL ASSEMBLY
TO PREVENT IT FROM ROLLING OUT OF HOUSING.
(4) Use Miller Special Tool 5048, 5048-3 Collets,
and L-4539-2 Button to remove the differential bear-
ing cone on the extension housing side.
(5) Use Miller Special Tool 5048, 5048-4 Collets,
and L-4539-2 Button to remove the differential bear-
ing cone on the bearing retainer side (Fig. 173) (Fig.
174) (Fig. 175).
