Apply a drop of oil in the piston's wrist pin bore before installing the wrist pin. Locate the oiler hole in the connecting rod and the skirt relief side of the new piston. Insert the connecting rod into the piston with the piston skirt relief and the oiler hole on the same side as shown. Line up the wrist pin bore in the rod with the wrist pin bore in the piston and slide the wrist pin through the larger opening of the piston. Note that the closed end of the wrist pin should be inserted first.
The orientation of the wrist pin is to help keep wrist pin cooler. Install the wrist pin clip G clip into the groove of the wrist pin bore of the piston. This will retain the wrist pin inside of the piston. Be sure to fully seat the G clip in the groove in the piston! Lower the piston and connecting rod assembly into the top of the engine case with the oiler hole of the connecting rod facing toward the crankshaft.
Apply a drop of oil onto the crank pin before installing the connecting rod onto the crank pin. Slide the connecting rod over the crank pin and rotate the crank pin to the bottom center of the crankcase. Lube the outside of the piston and slide the new sleeve into the engine case. Make sure the piston fits into the sleeve without binding. Press the sleeve all the way down into the engine case. Important: The slot in the lip at the back of the sleeve must key into the pin at the back of the engine case opening.
Do not install the cooling head until these two items are keyed into each other. Place the copper head gasket onto the sleeve and set the cooling head into the sleeve. Note that there are two slots notched through the cooling fins on each side of the cylinder head. These slots are for access to the engine mounting screws. The five head bolts should line up with the five holes on top of the engine case and the access slots on the cooling head should line up with the slots manufactured into the engine case.
Be careful not to damage the copper head gasket see picture for orientation. While pressing the head squarely onto the sleeve, thread the head bolts into the engine case just until they stop. Do not tighten down these bolts individually. It is very important to attain even pressure around the cooling head.
Slowly tighten each screw just a little at a time in a crossing pattern, see picture until each bolt becomes snug. Finish each bolt in the same pattern with 9. Connect the back plate with the starter shaft to the engine case. Important: The reliefs that are manufactured into the back plate must face up to match the ports inside of the engine case see picture for orientation. Key the starter shaft to the crank pin by slowly rotating the starter shaft as pressure is applied towards the crankshaft.
Once the starter shaft is keyed into the crank pin, join the back plate to the engine case and secure the assembly with the four 3x6CS screws. Install a new glow plug is recommended for the TRX 2.
Slide the split cone washer over the pilot shaft with the larger opening toward the engine case. Slide the flywheel over the pilot shaft and join it up with the split cone washer.
The split cone washer should fit inside of the tapered hole in the flywheel. Thread the flywheel nut all the way up to the flywheel and tighten the flywheel with Slide the clutch shoes onto the flywheel. Key the flywheel pins into the holes of the clutch shoes See picture for orientation of the clutch shoes.
Racer Tip: By reversing the direction of the clutch shoes, the clutch shoes will provide a little firmer bite against the interior wall of the clutch bell. This is useful on higher bite surfaces that offer a higher level of traction. Clean and lube both clutch bell bearings and install a ball bearing into each side the clutch bell and slide the clutch bell over the pilot shaft followed by the 5x8x0.
Fasten the 5. Clean the roller clutch with denatured alcohol and lube the roller clutch with Mobil 1 synthetic motor oil. Note that the roller clutch is to be installed onto the starter shaft so that the clutch engages the starter shaft clockwise and rotates freely counter-clockwise. Note that the engraved text on roller clutch faces the engine backplate for correct rotation. Mount the exhaust header and pipe assembly back onto the rear of the engine case. With the two 3x15CS screws.
