1. DESCRIPTION AND OPERATION
This section can be used as a quick reference for
general disassembly of the machine and its compo-
nents.
The chassis of the Backhoe Loader is manufactured
as a one piece unit on which the major assemblies
are attached or supported from.
The chassis are mainly of two kinds and differ from
one other according to the kind of backhoe attach-
ment that the backhoe loader should carry:
Z Center pivot: means that the backhoe is connected
directly to the chassis and cannot shift laterally (only
for 4WS).
Z Sideshift: means that the backhoe is installed on the
side shift support and can shift laterally on the chas-
sis guides.
The chassis change according to the machine steer-
ing (2WS or 4WS) because of the different wheel
shape; or because the machine can be equipped ei-
ther with "straight" loader arm (2WS machines) or
with "bent" loader arm (4WS machines).
