2.26.7 Bolt-on Screed Extension Installation.
NOTE
Equipment installation instructions
are the same for both the left and
right sides of the paving machine.
Illustrations show installation on the
right side of the paving machine.
To pave widths of 14 to 16 ft (4,3 to 4,9 m), the 1 ft auger
and fender extensions and the 2 ft auger and fender
extensions must be installed on both sides of the paving
machine. This
results in a total of 3 ft of auger and fender extension on
both sides of the paving machine. Also, there must be
an extension added to the screed frame and the screed
plate on both sides of the paving machine. The endgate
must be removed for installation of the screed frame
extension and screed plate extension and reinstalled
after extensions are installed. Both the 1 ft and the 2 ft
auger and fender extension must be compared to
determine the left auger and fender extension from the
right auger and fender extension. The screed frame
extension and screed plate extension will only fit on the
left or right side and are not interchangeable. Ensure the
spiral direction of the auger extension assemblies match
that of the mating auger shaft. Failure to install the
correct auger and fender extensions on the correct side
of the paving machine will cause the paving material to
build up in the auger chamber and not move the paving
material out in front of the screed.
Two persons are required to install the bolt-on screed
extension.
CAUTION
During removal of 1 ft screed plate,
ensure that the plate spacers around the
studs securing the screed plate to the
frame are not allowed to move or fall
from the stud. If plate spacers are
moved from their initial position on the
screed plate, a full screed alignment is
required on installation of the 1 ft screed
plate. Notify your supervisor or Unit
Maintenance.
During removal of bolts from the studs
on the extension screed plate, do not
allow the plate spacers to move or fall
off of the stud. If plate spacers are
moved from their initial position on the
extension
screed
plate
during
preparation for installation, a full screed
alignment is required. Notify your
supervisor or Unit Maintenance.
After installation of the 2 ft auger
extensions, extreme caution must be
taken
not
to
retract
the
screed
extensions into the augers and fenders
extensions. Damage to the endgate will
result if the endgate is retracted too far.
To reduce the paving width from between 16 ft (4,9 m)
and 14 ft (4,2 m), carefully retract the extension screed
to obtain the desired paving width.
