Transmission Shaft Assembly

The drive shaft gears can be recognized by size: the gear with the smallest diameter is 1st gear, and the largest one is 6th gear. Be sure that all parts are put back in the correct sequence and all circlips and washers are properly in place.
Install the 3rd/4th gear onto the drive shaft with their oil holes aligned.
Install the 5th and 6th gear bushings onto the drive shaft with their oil holes aligned.
The output shaft gears can be recognized by size: the gear with the largest diameter is 1st gear, and the smallest one is 6th gear. Be sure that all parts are put back in the correct sequence and all circlips and washers are properly in place.
Install the 6th gear onto the output shaft with their oil holes aligned.
Install the 1st, 2nd and 3rd/4th gear bushings onto the output shaft with their oil holes aligned.

Fit the steel balls into the 5th gear holes in the output shaft.

Transmission Shaft Assembly

NOTICE

Do not apply grease to the balls to hold them in place. This will cause the positive neutral finder mechanism to malfunction.

After assembling the 5th gear with steel balls in place on the output shaft, check the ball-locking effect that the 5th gear does not come out of the output shaft when moving it up and down by hand.

Check that each gear spins or slides freely on the transmission shafts without binding after assembly.
