STEP 3:

Remove the EZ-Start gearbox by removing the three

3x8mm round-head machine screws.

STEP 4:

Use a 2.5mm hex driver to remove the yellow ground

wire from the engine mount. Move the EZ-Start wiring

harness out of the way.

STEP 5:

Use a 2.5mm hex driver to remove the three

remaining 3x10mm cap-head machine screws from

the engine mount.

STEP 6:

Pull the engine from the chassis. Turn the engine

so that the throttle linkage to the carburetor will

come out.

STEP 9: Changing the piston and sleeve

assembly

Use a 5/16 inch nut driver to remove the glow plug and

copper gasket.

STEP 10:

Use a 2.5mm allen wrench to remove the four 3x12mm

cap-head screws that fasten the cylinder head. Rock

the cylinder head gently from side to side to release it

from the sleeve. Note the thin aluminum head gaskets.

We recommend that you replace these gaskets with

new ones upon reassembly.

STEP 11:

Remove the backplate and the starter

shaft. Replace the backplate gasket

with a new one during assembly.

STEP 12:

The piston and sleeve are a matched set. When the

piston and sleeve are disassembled, they must be

reassembled in the same orientation. Use a hobby

knife to scratch a mark to indicate the location of the

piston in relation to the pinning of the sleeve.

STEP 8:

Removing the carburetor is not necessary to rebuild

the engine, unless you intend to replace the internal

bearings of the engine. Remove the carburetor by

loosening the 3mm locknut and pulling the carburetor

straight up.



STEP 15:

Remove the connecting rod and piston through the top

of the crankcase.

STEP 16:

To remove the connecting rod from the piston, use

a sharp-pointed tool to remove the small metal

G-clip in the side of the piston. Do not re-use the old

G-clip. When installing a new connecting rod, use the

supplied new G-clip.

STEP 21:

Remove the crankshaft by pulling it straight out of the

crankcase.

STEP 22:

The bearings are press-fit into the crankcase. To

remove them, the crankcase must be heated with a

heat gun or torch. The crankcase will expand with

heat and release the bearings. To avoid the possibility

of burns or other damage, do not attempt remove the

bearings. Clean the bearings by flushing them with

denatured alcohol and then place one or two drops of

after-run oil on the races.

STEP 23:

Before installing a new connecting rod, you can

increase connecting rod life by polishing the crankshaft

journal. Use 1200 grit sandpaper to remove the

surface scratches followed by liquid metal polish to

buff the crankshaft journal to a bright, smooth shine.

Rinse thoroughly with denatured alcohol. Lube with

after-run oil.

STEP 24:

Use the 1200 grit sandpaper and the liquid metal

polish on the wrist pin also. Rinse thoroughly with

denatured alcohol and lube with after-run oil.

STEP 13:

Pull the sleeve straight up and out of the crankcase. If

the sleeve will not move, rotate the crankshaft until the

sleeve pushes up.

STEP 14:

Rotate the crankshaft to bottom dead center. Lightly

grab the connecting rod with a pair of needlenose

pliers and gently pull it off of the crankshaft journal.

STEP 17: Removing the clutch and flywheel

It is not necessary to remove the clutch assembly

unless you are servicing the clutch, crankshaft, or

engine bearings. Use the tip of a small screwdriver to

remove the E-clip which holds the clutch bell gear.

STEP 18:

Remove the clutch bell gear and the clutch shoes.

Note that there are two 5x8mm Teflon®washers, one

on each side of the clutch bell gear. Check the clutch

shoes for excessive wear

or cracking around the pin

holes. If the clutch shoes

are worn to the point that

the clutch spring contacts

the clutch bell, then the

shoes must be replaced.

STEP 19:

Grip the flywheel with a

pair of pliers (locking pliers

work best). Remove the

clutch adapter nut with a

10mm deep socket. Hold

the engine just above your

workbench and tap the

flywheel from behind with a

non-marring hammer (plastic or wood). Several easy

blows may be necessary to release the flywheel and

split beveled cone.

STEP 20:

The flywheel and the split-beveled cone should pull

smoothly off of the crankshaft.



STEP 36:

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

a 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 a 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 Teflon®washer

followed by the clutch

bell gear (with bearings

installed). Install the

remaining 5x8mm Teflon®

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).

Additional charges can result from the following:

The product being returned for warranty service should be cleaned of

excess dirt and grime accumulations that would hinder repair. Excessively

dirty models with large amounts of caked-on mud and oily grime may

be subject to an additional cleaning charge of $25.00(US) before repairs

can proceed. Avoid this potential charge by cleaning the model before

returning it for service.

“Basket cases” of disassembled models returned for warranty service may

be subject to additional fees for reassembling components not related

to the warranty repair (if necessary to allow the repaired product to be

adequately tested). Standard repair fees are currently $45.00/hour, billed

in 15-minute increments with a one-hour minimum. To avoid this charge,

do not disassemble the model before returning it for service.
