(48) Set up dial indicator as shown in (Fig. 138)
and measure 2/4 clutch clearance. Press down on
clutch pack with finger and zero dial indicator.2/4
clutch pack clearance is 0.76-2.64 mm
(0.030-0.104 in.).If clearance is outside this range,
the clutch is assembled improperly.There is no
adjustment for 2/4 clutch clearance.

(52)DETERMINING #4 THRUST PLATE
THICKNESS / INPUT SHAFT END PLAY:
(a) Select the thinnest #4 thrust plate thickness
and install to input clutch assembly (Fig. 142). Use
petrolatum to retain.
(b) Install input clutch assembly into position
and verify that it is completely seated by viewing
through input speed sensor hole. If view through
input speed sensor hole is not as shown in (Fig.
143), the input clutch assembly is not seated prop-
erly.
(c) Remove oil pump o-ring (Fig. 144).Be sure
to reinstall oil pump o-ring after selecting the
proper #4 thrust plate.
(d) Set up input shaft for measurement with
Indicator Set C3339 and End Play Set 8266 as
shown in (Fig. 145).
(e) Measure the input shaft end play with the
transaxle in the vertical position.Input shaft end
play must within 0.005 to 0.025 inch.For exam-
ple, if end play reading is 0.055 inch, select No. 4
Thrust Plate which is 0.071 to 0.074 thick. This
should provide an input shaft end play reading of
0.020 inch which is within specifications.
(f) Refer to the No. 4 thrust plate chart to select
the proper No. 4 thrust plate:

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 295). The
oil pump consists of an inner and outer gear, a hous-
ing, 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 suctionat 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.
STANDARD PROCEDURE - OIL PUMP VOLUME
CHECK
Measuring oil pump output volume will determine
if sufficient flow to the transmission oil cooler exists,
and whether or not an internal transmission failure
is present.
Verify that transmission fluid is at the proper
level. If adding fluid is necessary, fill to the proper
level with Moparž ATF+4 (Automatic Transmission
Fluid±Type 9602). The following procedure is to
check oil pump output volume:
(1) Using hose cutters or a suitable blade, cut the
ªto coolerº (Fig. 296) line off flush with the cooler
inlet fitting and place a collection container under
the open line .
CAUTION: With the fluid set at the proper level,
fluid collection should not exceed (1) quart or inter-
nal damage to the transmission may occur.
(2) Start engine and runat curb idle speed, with
the shift selector in neutral.
