(33) Using moderate pressure, press down and
hold (near indicator) reverse clutch disc with screw-
driver or suitable tool and zero dial indicator (Fig.
264). 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. 265).
(38) Install the underdrive shaft assembly (Fig.
266).
(39) Install the #3 thrust washer to the underdrive
shaft assembly. Be sure five tabs are seated properly
(Fig. 267).

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 271). 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 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.
DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage.
(1) Remove the reaction shaft support-to-pump
body bolts (Fig. 272).
(2) Remove reaction shaft support from pump
housing (Fig. 273).
(3) Remove the pump gears (Fig. 274) and check
for wear and damage on pump housing and gears.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 275). Clearance should be
0.089–0.202 mm (0.0035-0.0079 in.).
