Dodge Sprinter. Manual — part 283
INPUT CLUTCH K3
DISASSEMBLY
(1) Remove snap-ring (1) (Fig. 94) from outer mul-
tiple-disc carrier.
(2) Remove multiple-disc pack (2) and disk spring
(3) from outer multiple-disc carrier. Note which
clutch disc is removed just prior to the spring plate
(3) for re-assembly. If the clutch discs are re-used,
this disc must be returned to its original position on
top of the spring plate.
(3) Place Multi-use Spring Compressor 8900 (9)
(Fig. 94) on disc spring (5) and compress the spring
until the snap-ring (4) is exposed.
(4) Remove snap-ring (4).
(5) Remove spring plate (5) and piston (6) from
outer multiple-disc carrier.

ASSEMBLY
(1) Install piston (6) (Fig. 95) in the outer multi-
ple-disc carrier (8). Check sealing ring (7), replace if
necessary. The rounded off edges of the sealing ring
must point outwards.
(2) Insert disc spring (5). Insert disc spring with
the curvature towards the piston.
(3) Mount the Multi-use Spring Compressor 8900
(9) on the spring plate and clamp until the snap-ring
groove is exposed.
(4) Insert snap-ring (4). The collar of the snap-ring
must point towards the multiple-disc pack.
CAUTION: When working with double sided friction
discs, an externally lugged steel plate is installed
first, followed by a friction disc, and continuing on
until all the required discs are installed. When work-
ing with single sided friction discs, an externally
lugged disc is installed first, followed by an inter-
nally lugged disc, and continuing on until all the
required discs are installed. All single sided discs
are installed with the friction side up.
NOTE: Pay attention to the sequence of discs. If the
original clutch discs are reused, be sure to return
the disc identified on disassembly as belonging on
top of the spring plate (3) to its original location.
NOTE: Place new friction multiple-discs in ATF fluid
for one hour before installing.
(5) Install disk spring (3) and multiple-disc pack
(2) in outer multiple-disc carrier (8).
(6) Insert snap-ring (1).

(7) Measure the K3 clutch clearance by mounting
Pressing Tool 8901 (1) (Fig. 96) on outer multiple
disc.
(8) Using a lever press, compress pressing tool as
far as the stop (then the marking ring is still visible,
see small arrow).
(9) For transmissions using double sided friction
discs, use a feeler gauge to determine the play “L”
(Fig. 97) at three points between the snap-ring (8)
and outer multiple-disc (2).
(10) During the measurement the snap-ring (8)
must contact the upper bearing surface of the groove
in the outer multiple-disc carrier.
(11) The correct clutch clearance for transmissions
with double sided friction discs is 2.3-2.7 mm (0.091-
0.106 in.) for three friction disc versions, 2.4-2.8 mm
(0.095-0.110 in.) for four disc versions, and 2.5-2.9
mm (0.099-0.114 in.) for five disc versions.
(12) Adjust with snap-ring (8), if necessary. Snap-
rings are available in thicknesses of 2.0 mm (0.079
in.), 2.3 mm (0.091 in.), 2.6 mm (0.102 in.), 2.9 mm
(0.114 in.), 3.2 mm (0.126 in.), and 3.5 mm (0.138
in.).
(13) For transmissions using single sided friction
discs, use a feeler gauge to determine the play “L”
(Fig. 98) at three points between the snap-ring (7)
and outer multiple-disc (2).
(14) During the measurement the snap-ring (7)
must contact the upper bearing surface of the groove
in the outer multiple-disc carrier.
(15) The correct clutch clearance for transmissions
with single sided friction discs is 2.3-2.7 mm (0.091-
0.106 in.) for six friction disc versions, 2.4-2.8 mm
(0.095-0.110 in.) for eight disc versions, and 2.5-2.9
mm (0.099-0.114 in.) for ten disc versions.
(16) Adjust with snap-ring (7), if necessary. Snap-
rings are available in thicknesses of 2.0 mm (0.079
in.), 2.3 mm (0.091 in.), 2.6 mm (0.102 in.), 2.9 mm

ELECTROHYDRAULIC UNIT
DESCRIPTION
The electrohydraulic control unit (Fig. 99) com-
prises the shift plate (13) made from light alloy for
the hydraulic control and an electrical control unit
(12). The electrical control unit (12) comprises of a
supporting body made of plastic, into which the elec-
trical components (1 - 11) are assembled. The sup-
porting body is mounted on the shift plate (13) and
screwed to it.
Strip conductors inserted into the supporting body
make the connection between the electrical compo-
nents and a plug connector. The connection to the
wiring harness on the vehicle and the transmission
control module (TCM) is produced via this 13-pin
plug connector with a bayonet lock.
ELECTRICAL CONTROL UNIT
The electric valve control unit (7) (Fig. 100) con-
sists of a plastic shell which houses the RPM sensors
(1,12), regulating solenoid valves (3, 4), solenoid
valves (5, 6, 10), the TCC solenoid valve (11), the
park/neutral contact (9), and the transmission oil
temperature sensor (8). Conductor tracks integrated
into the shell connect the electric components to a
plug connection (2). This 13-pin plug connection (2)
establishes the connection to the vehicle-side cable
harness and to the transmission control module
(TCM). With the exception of the solenoid valves, all
other electric components are fixed to the conductor
tracks.
HYDRAULIC CONTROL UNIT
Working Pressure (Line Pressure or Operating Pressure)
(p - A)
The working pressure provides the pressure supply
to the hydraulic control and the transmission shift
elements. It is the highest hydraulic pressure in the
entire hydraulic system. The working pressure is reg-
ulated at the working pressure regulating valve in
