:
Pay particular attention to the torque tube. Ensure that it is perfectly straight.
Installation of Packer Panel
Install the packer panel in the approximate reverse order of disassembly. Pay particular attention to
the installation of roller and bearing assemblies (see Bearing Placement on page 110 and Roller
Replacement on page 111) .
Carrier Panel
The correct method of operation is thoroughly described in the 2R-III™ Operator’s Manual . Our
policy is not to describe the many different ways in which a unit might be incorrectly operated;
however, in an attempt to provide maintenance personnel with clues that may assist in the diagnosing
of a reoccurring carrier/packer panel concern that might be operator-induced, we offer the following:
Skimming is a result of the operator interrupting the movement of the packer panel and stopping the
packer panel before it rotates perpendicular (90 degrees) to the carrier panel. When the packer panel
is not allowed to fully rotate and the carrier is then moved toward the “home” position, a shear load is
induced to the lower channel of the carrier panel. The carrier panel lower channel is designed for
compression or tension, not shear loads. If the lower channel on the carrier panel cracks or the center
bearing straps consistently break, suspect that the unit is being skimmed.
Short cycling is when the carrier panel is stopped before it completely lowers. The operator then
attempts to penetrate down through the refuse that is in the hopper with the packer panel. This
incorrect method of operation results in much the same kind of failures as skimming because the
torque tube and lower carrier channel are put into a shear situation. This incorrect method of
operation will also adversely affect the hopper bottom because the force of the packer panel cylinders
is being dissipated down through the refuse and into the hopper structure.
