7.16 Axles/traveling drive
Description of traveling drive
The axial-piston variable displacement motor of the
machine travel hydraulics is installed on the transfer
gearbox. The transfer gearbox is connected to the rear
axle of the machine. The front axle is driven via the
cardan shaft. The wheels are driven via two reduction
gears on each axle.
The axle (differential, axle tubes) shares a common oil
supply. The transfer gearbox and wheel reduction gears
have their own oil supply.
The oil level can be checked on the differential housing
and on the wheel reduction gears!
Check plugs are located in the same positions on the front
and rear axles.
Perform maintenance on the gearbox and axles according
to the inspection intervals specified in this Operator’s
Manual.
