one
side
of
the
clutch

Turn
the
gear
over
and
install
the
other
ball
bearing.
STEP
34:

STEP
25:
To
assemble
the
connecting
rod
and
piston,
place
a
drop
of
castor
oil
in
the
top
end
of
the
connecting
rod.
Insert
the
wrist
pin
through
the
piston
and
the
top
of
the
connecting
rod.
Secure
the
wrist
pin
with
the
G-clip.
Make
sure
the
G-clip
fits
securely
into
the
groove
machined
in
the
piston.
Be
careful
not
to
scratch
the
sides
of
the
piston.
STEP

Reinstall
the
crankshaft
into
the

so
that
the
notch
in
the
sleeve
will
line
up
with
the
pin
in
the
crankcase.
Holding
the
engine
upside
down
will
make
it
easier
for
the
sleeve
to
go
over
the
piston.
STEP

gaskets
on
the
head.
Use
