10. Install piston and connecting rod assembly to crankshaft.
I
Move crankshaft pin to be removed to BDC.
I
Align cylinder position with cylinder No. on connecting rod to
install piston and connecting rod assembly.
I
Using piston ring compressor (multi-purpose tool), install piston
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, prevent
the big end of connecting rod from interfering with oil jet.
11. Install connecting rod caps and mounting nuts.
I
Align cylinder No. stamped on connecting rod with that on cap
to install connecting rod cap.
I
After tightening nuts, check crankshaft for smooth rotation.
I
Check connecting rod side clearance.
Refer to EM-71, “CONNECTING ROD SIDE CLEARANCE”.
12. Install rear oil seal and retainer assembly.
I
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 bushing
by the length shown in the figure.
14. Install rear plate.
