10. Install piston and connecting rod assembly to crankshaft.
+Move crankshaft pin to be removed to BDC.
+Align cylinder position with cylinder No. on connecting rod to
install piston and connecting rod assembly.
+Using piston ring compressor (multi-purpose tool), install pis-
ton and connecting rod assembly with front mark on piston
crown facing toward the front side of engine.
CAUTION:
When installing piston and connecting rod assembly, pre-
vent the big end of connecting rod from interfering with oil
jet.
11. Install connecting rod caps and mounting nuts.
+Align cylinder No. stamped on connecting rod with that on
cap to install connecting rod cap.
+After tightening nuts, check crankshaft for smooth rotation.
+Check connecting rod side clearance.
Refer to EM-1072, ªCONNECTING ROD SIDE CLEAR-
ANCEº.
12. Install rear oil seal and retainer assembly.
+Apply a continuous bead of liquid gasket to rear oil seal and
retainer assembly as shown in the figure.
13. Press fit pilot bushing into flywheel (M/T model).
1) Using drift with outer diameter of 35 mm, press fit spacer until
it is in contact with the flywheel to prevent displacement at
removal.
2) Using drift with outer diameter of 20 mm, press fit pilot bush-
ing by the length shown in the figure.
14. Install rear plate.
+Refer to the figure for gasket installation direction.

15. Install removed parts to engine in the reverse order of disas-
sembly.
16. Remove engine from engine stand.
17. Install flywheel (M/T model) or drive plate (A/T model).
+Install pilot converter, drive plate, and reinforcing plate in
direction shown in the figure.
+Using the same method as disassembly, secure crankshaft
and tighten mounting bolts.
+Tighten mounting bolts for flywheel or drive plate in order
shown in the figure.
