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 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 Stampede comes stock with an 18-tooth clutch bell gear that 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 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 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).
