Dodge Sprinter. Manual — part 293
OPERATION
The holding clutches (Fig. 166) connect the annu-
lus gear, sun gear, or planetary carrier of a planetary
gear set against the transmission housing in order to
transmit the drive torque.
If the piston (16) on multiple-disc holding clutch
B1 (1) is subjected to oil pressure, it presses the
internal (3) and external discs (2) of the disc set
together. The internally toothed disc carrier (15)
locks the sun gear (14) against the housing. The
planetary pinion gears (13) turn on the sun gear (14).
If the multiple-disc holding clutch B2 (5) is actu-
ated via the piston (7), the piston compresses the disc
set. The internally toothed disc carrier (8) locks the
sun gear (12) against the housing. The planetary pin-
ion gears (11) turn on the sun gear (12).
If the multiple-disc holding clutch B3 (4) is actu-
ated via the piston (6), the planetary carrier (9) and
the annulus gear (10) are locked. When the multiple-
disc brake B3 (4) is actuated, the direction of rotation
is reversed.

for re-assembly. If the clutch discs are re-used, this
disc must be returned to its original position on top
of the disc spring.
(4) Place the Multi-use Spring Compressor 8900
(8) (Fig. 168) on disc spring (3) and compress the
spring until the snap-ring (4) is exposed.
(5) Remove snap-ring (4).
(6) Remove piston (2) from the outer multiple-disc
carrier by carefully blowing compressed air into the
bore (A).

ASSEMBLY
NOTE: Check vulcanized gasket, replace if neces-
sary.
(1) Install piston (2) (Fig. 169) in outer multiple-
disc carrier (1).
(2) Place compressor (8) on disc spring (3) and
compress until the groove of the snap-ring is exposed.
NOTE: The collar of the snap-ring must point
towards the multiple-disc pack. After installing,
check snap-ring for correct seat.
(3) Insert snap-ring (4) (Fig. 169).
(4) Insert disc spring (2) (Fig. 170) in the outer
multiple-disc carrier. Observe the disc spring (2)
installation position. The lugs of the disc spring (2)
