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

34:

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

with the pin

in

the crankcase.

Holding

the engine

upside

down

will

make it easier

for the sleeve

to go

over the piston.

STEP

29:

Install new

head gaskets on the

head. Use one

thick and one thin gasket. Reinstall

the head using

the 3x12mm cap-head

machine

screws. Tighten

the

screws in

small increments, in a

criss-cross pattern,

until all the screws are tight.

STEP

30:

Reinstall

the starter shaft. Align the notch in the starter

shaft with the crankshaft journal pin (arrow).
