Chapter 7. Rear axle and brakes
1. GENERAL DESCRIPTION
The rear axle system is of the central axle type,which contains the final reduction gears, differential
gears with diff-lock,and brakes.The power from the engine is transmitted to the right and left wheel
pinions through the differential gears,and reduced in the revolution to the rear wheels by the wheel
gears. A wet,multi-Disc, mechanical operated brake system is employed.Each of the brakes has 2
friction plates and can produce significant braking force with excellent durability. The two actuators
work to push their friction plates in opposite directions,that is,outward,so that stable braking force can
be realized in both forward and reverse movements of the tractor. A dif-lock mechanism which is
housed in the right-hand rear axle housing is employed to lock the differential gears and is activated by
depressing the dif-lock pedal,resulting in the same rotary speeds of both wheels.
