Procedure
Cutting unit models 03860, 03861, and 03862 can
be installed at any of the mounting locations on
the traction unit. Figure 3 shows the orientation of
the hydraulic drive motor for each of the locations.
For any of the locations requiring the motor to
be mounted on the right end of the cutting unit,
install a counter weight on the left end of the
cutting unit. For the locations requiring the motor
to be mounted on the left end, install a counter
weight on the right end of the cutting unit.
Note: Counterweight mounting capscrews are
shipped installed on the right bearing housing of
the cutting units. The capscrews on left bearing
housing are to be used for securing the hydraulic
motor.
