3-14. Removing/Disassembling/Assembling Engine Block (cont.)
ASSEMBLING
1) Assemble Piston so that the triangular marking on
its top is placed on the exhaust muffler installation
side (the longer Crankshaft side). (Fig. 56)
2) Piston ring is not reversible when assembled
to Piston. Adjusting the end-gap of Piston ring
fit in the groove of Piston; first the lower Piston
ring, then the upper one. (Fig. 57)
Caution:
1) Because Piston ring is easily broken, take care
not to expand excessively when installing new
one.
2) When inserting Piston into Cylinder, be very
careful with the position of the end-gap of
Piston ring, never placing Piston ring over the
knock pin. It will result in broken Piston ring
to force Piston into Cylinder with the ring
placed over the knock pin.
3) Crankshaft is not reversible when assembled to
Cylinder. Place it so that the longer shaft faces
the Exhaust muffler installation side. (Fig. 58)
4) Apply "Three bond 1215" to the matching surface
between Crankcase and Cylinder; it is enough to
apply the adhesive only to the shaded portion of
Crankcase.
And then aligning the protrusion on Crankcase
with one on Cylinder as illustrated in Fig. 59,
assemble them together.
