Belt Tensioning
The pulley assembly includes a mechanism to automatically tension the drive belt with a spring and a
clamp to lock the pulley in place when the proper tension has been established. Improper belt tensioning
can lead to transport errors. Additionally, ensure the belt is properly installed into each end of the bearing
at the black timing belt. The belt should be fully seated to the back and the black marks on the belt inserted
so they are invisible to provide the pulley optimal tension.
During normal operation the spring is extended
• RSH Belt Tension Spring sets the belt tension
• Locking Disk, or wheel, holds tension adjustment
Pulley is lubricated during Planned Maintenance procedures. This reduces friction between the sides of
the belt and the pulley shoulders.
NOTE: For additional information refer to the RSH Preventative Maintenance ISA
116-050 or 126-034 most current revision and the ARCHITECH RSH Service
and Support Manual.
Diagnostic Information:
• Carrier Transport Belt rising up the pulley shoulder could indicate an alignment or lubrication
issue
• To prevent damage, ensure the pulley locking wheel is loosened prior to using the Tension
Release Bolt
• Lubricate Pulley Wheel during Planned Maintenance and anytime the assembly is removed or
replaced
• Replace the Belt if the number of strands is different than 10 or cords are exposed from the
belt
