STEP
36:
Reinstall
the carburetor with a new o-ring, header,
a
NEW glow plug, and engine mount. Use a new
header
gasket when reinstalling the header
on
the engin
e. Reinstall the engine
in the truck in the
reverse order of removal. Don’t forget to reconnect the yellow
groundi
ng wire to the engine mount. The
rebuilt engine must
now be broken in.
STEP
31:
Reinstall the backplate and a new backplate gasket with the 3x8mm cap-head
machine
screws. Tighten
the screws in small increments in a criss-cross pattern until all the screws are tight.
STEP
32:
Install the
appropr
iate size ball bearin
g
into one side of
the clutch bell
gear. The Nitro Stampede comes stock
with an 18-tooth clutch bell
gear that requires
5x11mm
ball beari
ngs.
STEP
33:
Turn the gear over and install the other ball bearing.
STEP

Install the
split-be
veled cone onto
the crankshaft.
Next, install
the flywheel.
Install
the clutch
adapter
nut with a 10mm deep
socket.
Grip the flywheel
with plier
s
while tightening
the adapter nut.
STEP
35:
Install the clutch shoes exactly as shown in the drawing
(leading
edge
engagement). Next,
install
a 5x8mm PTFE
washer
followed
by the clutch
bell gear (with bearings installed). Install the remaining
5x8mm PTFE
washer followed
by the
E-clip (see step 14).
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 connec
ting rod. Secure
the wrist pin
with
the G-clip. Make sure the G-clip fits securely
into
the groove machin
ed in the piston. Be careful not to
scratch the sides of
the piston.
STEP
26:
Reinstall
the crankshaft into the engine
and make
sure that it spins
freely. Insert the connecting
rod and
piston assembly through the top
of
the crankcase. The
G-clip should face
the
carburetor. Put
a
drop of
castor
or
after-run
oil in the
bottom
end of
the
connecting
rod. Use your fingers to gently push the end of the connecting rod over the crankshaft journal.
STEP
27:
Place
another drop of oil
on the connecting
rod bushing.
Rotate the crankshaft several
times to distribute
the oil.
STEP
28:
Insert the sleeve into the top of the crankcase. Rotate the sleeve
so that the notch
in
the sleeve
will
line
up

the crankcase.
Holding
the engine
upside
down
will
make it easier
for the sleeve
to go
over the piston.

criss-cross pattern,
until all the screws are tight.
STEP

Reinstall
the starter shaft. Align the notch in the starter
shaft with the crankshaft journal pin (arrow).
