3. LOCATION OF STEEL BALL
Install the steel ball at the location shown.
2. INSTALLATION OF REACTION SHAFT SUPPORT
(I) Assemble the reaction shaft support and the pump
housing, and tighten the bolts by fingers.
(2) Insert the special tool (Guide Pin, MD998336-01) into
the oil pump mounting bolt hole and clamp the
periphery with the special tool (Band, MD998335-01) to
position the support and housing.
(3) Tighten the five bolts to the specified torque.
(4) Make sure that the oil pump gear turns freely.

12. INSTALLATION OF SNAP RING
(I) Using the special tool, compress the return spring.
(2) Using the snap ring pliers, install the snap ring.
10. INSTALLATION OF CLUTCH PLATE / 8. CLUTCH REAC-
TION PLATEInstall the clutch plate and reaction plate so that the areas
where one tooth is missing [indicated by
@] are aligned
with each other.
NOTEThis ensures that the automatic transmission fluid escapes4~well and the plate and disc are cooled efficiently.
7. SELECTION OF SNAP RING
Check clearance between the snap ring and clutch reaction
plate. To check the clearance, hold entire circumference of
the clutch reaction plate down with 50 N (11
Ibs.) force. Ifclearance is out of standard value, select a snap ring to
obtain the standard value.
Standard value: 1.0
- 1.2 mm (.034 - .047 in.)
2. INSTALLATION OF INPUT SHAFT
Align the oil groove in the input shaft with the alignment
mark on the rear clutch retainer.
