fork
Set transmission main shaft assembly and drive pinion
shaft assembly in position (so there is no clearance
between the two when moved all the way to the front).
Select suitable 1st-2nd, 3rd-4th and 5th shifter fork so that
coupling sleeve and reverse driven gear are positioned in
the center of their synchronizing mechanisms.
