Chrysler 300M, Dodge Interpid. Manual — part 325
(24) Install OD reaction plate flat snap ring (Fig.
313).
(25) Measure OD clutch pack clearance. Set up
dial indicator on top of the OD/Reverse reaction plate
as shown in (Fig. 314).
(26) Zero dial indicator and apply 30 psi (206 kPa)
air pressure to the overdrive clutch hose on Tool
8391. Measure and record OD clutch pack measure-
ment in four (4) places, 90° apart.
(27) Take average of four measurements and com-
pare with OD clutch pack clearance specification.
The overdrive (OD) clutch pack clearance is
1.07-3.25 mm (0.042-0.128 in.).
If not within specifications, the clutch is not
assembled properly. There is no adjustment for the
OD clutch clearance.
(28) Install reverse clutch pack (two fibers/one
steel) (Fig. 315).
(29) Install reverse clutch reaction plate with the
flat side down towards reverse clutch (Fig. 316).

(30) Tap reaction plate down to allow installation
of the reverse clutch snap ring. Install reverse clutch
snap ring (Fig. 317).
(31) Pry up reverse reaction plate to seat against
snap ring (Fig. 318).
(32) Set up a dial indicator on the reverse clutch
pack as shown in (Fig. 319).
(33) Using moderate pressure, press down and
hold (near indicator) reverse clutch disc with screw-
driver or suitable tool and zero dial indicator (Fig.
320). When releasing pressure, indicator should
advance 0.005-0.010. as clutch pack relaxes.
(34) Apply 30 psi (206 kPa) air pressure to the
reverse clutch hose on Tool 8391. Measure and record
reverse clutch pack measurement in four (4) places,
90° apart.

(35) Take average of four measurements and com-
pare with reverse clutch pack clearance specification.
The reverse clutch pack clearance is 0.89-1.37
mm (0.035-0.054 in.). Select the proper reverse
clutch snap ring to achieve specifications:
(36) To complete the assembly, reverse clutch and
overdrive clutch must be removed.
(37) Install the #2 needle bearing (Fig. 321).
(38) Install the underdrive shaft assembly (Fig.
322).
(39) Install the #3 thrust washer to the underdrive
shaft assembly. Be sure five tabs are seated properly
(Fig. 323).
(40) Install the #3 thrust plate to the bottom of the
overdrive shaft assembly. Retain with petrolatum or
transmission assembly gel (Fig. 324).

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case. The oil pump
assembly (Fig. 327) consists of an inner and outer
gear, a housing, and a cover that also serves as the
reaction shaft support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate,
the
clearance
between
the
gear
teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
