[2] RANGE GEAR SHIFT SECTION
Two kinds of power flow are selected by operating
the range gear shift lever to shift the 16T-24T shifter gear
(4) on the spiral bevel gear shaft (3).
 Low Range
17T Gear Shaft (2) → Shifter Gear (24T) (4) → Spiral
Bevel Pinion Shaft (3).
 High Range
25T Gear (1) → Shifter Gear (16T) (4) → Spiral

[3] FRONT WHEEL DRIVE SECTION
2-wheel drive or 4-wheel drive is selected by
changing the position of 19T shifter gear (2) with the front
wheel drive lever.
 Front Wheel Drive "Disengaged"
When the front wheel drive lever is set to
"Disengaged" position, the 19T shifter gear (2) is
neutral and power is not transmitted to the front wheel
drive shaft (1).
 Front Wheel Drive "Engaged"
When the front wheel drive lever is set to "Engaged"
position, the 19T shifter gear (2) slides to the right to
engage with 13T-25T gear shaft (5). Therefore, the
power from spiral bevel pinion shaft (3) is transmitted to
the front wheel drive shaft (1) through the gears.
