5.8 Drive Pressure Adjustment
1. Once the belt is installed and spliced, the pressure assemblies may be adjusted for correct drive
pressure.
2. There is a pressure assembly in between each module that requires tensioning. In most cases
this will be every 60”, but the pressure module spacing may vary depending on bed length.
Tension both the pressure assemblies at each bed break that were installed in section 5.3, and
the pre-installed pressure assemblies within each bed section.
3. Fully tighten each pressure assembly nylock (79) until the lower pressure plate (80) contacts the
bottom of the bed spacer on both sides. This setting gives maximum drive force, and further
tightening will not increase drive. See Figure 8: Pressure Assembly Installation Detail in section
5.3 for details.
