20. Lubricate the sealing lip of the differential seal with clean transmission oil and install it into the crankcase.
21. Install the spring into the reverse gear lever axle.
22. Place the shift fork assembly onto the output shaft assembly. Insert the shift fork assembly into the transmission case.
23. Carefully slide the shift fork assembly slightly up and out of the mounting lug by tilting the output shaft assembly. Pull the stem out as far as it will go and rotate it 90° from the neutral position. Place the ball at the end of the reverse gear lever shaft and rotate the rod to the neutral position. Carefully insert the rod into the corresponding protrusion of the transmission housing.
24. Insert the spring pin into the tip of the shift fork rod and install it in place.
25. Install the double-arm lever assembly that connects the shift lever to the shift fork rod end.
26. Install a new O-ring on the double-arm lever shaft. Lubricate the double-arm lever with clean transmission oil and install it. Attach the lever with a spring pin.
27. Install the reverse gear selector lever and insert the 5th gear and reverse gear selector rod into place so that the recess on the rod faces outward. The hole in the leash shaft must be aligned with the reverse gear selector.
28. Install the intermediate gear and reverse shaft.
29. On 5-speed models, use RTV sealant to install the oil passage to the transmission case.
30. Connect the transmission housing parts so that the differential is at the bottom. You may need to align the magnet with the slot in the top half of the crankcase.
31. Install the transmission case bolts and tighten them to the specified torque in a diagonal sequence.
32. Install the leash shaft lock bolt together with its sealing washer. Tighten the bolt securely (5-speed gearbox).
