5.3.3 Range shift module
The range shift module is a constant-mesh type
transmission.
(1) Operating the range shift lever activates the
shifter (A) (B) so that they engage gears
21L, 45L and 53.
(2) These gears are always engaged with the
reduction gear (C) and the range shift shaft
(D). Then the rotation (E) of the connecting
shaft is transferred to the differential gear
module (F).
5.3.4 Front drive
(1) When operating the front drive lever to front
drive ON position, the shifter (H) moves to
the gear 54R to engage the front drive shaft
(G) and the gear 54R.
(2) Then the rotation of range shift shaft (D) is
transferred to the front drive shaft (G)
through the gear 54R and the sifter (H).
