STEP 36:

Reinstall the carburetor with a new o-ring, header, 

NEW glow plug, and engine mount. Use a new

 

header

 gasket when re-installing the header on 

the engine. Reinstall the engine in the truck in the 

reverse order of removal. Don’t forget to reconnect 

the yellow grounding 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 appropriate size ball bearing into one side of 

the clutch bell gear. The Nitro Sport comes stock with 

an 18-tooth clutch bell gear which requires 5x11mm 

ball bearings.

STEP 33:

 

Turn the gear over and install the other ball bearing.

STEP 34: 

Install the split-beveled cone onto the crankshaft. 

Next, install the flywheel. Install the clutch adapter 

nut 

with 

10mm deep

 

socket. Grip the flywheel 

with pliers while tightening 

the adapter nut. 

STEP 35:

Install the clutch shoes 

exactly as shown in the 

drawing (leading edge 

engagement).  Next, install 

a 5x8mm washer followed 

by the clutch bell gear 

(with bearings installed). 

Install the remaining 

5x8mm 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 

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 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).
