Bend-Tech Dragon A400 - Drive Belt Alignment; Drive Pulley Spacing

1.4 Drive Belt Alignment
If the Drive Belt Pulley is not aligned properly it will cause the Drive Belt to ride improperly on
the idler pulleys and potentially lead to Drive Belt derailing, ipping on the pulleys, pushing the
Drive Belt Pulley washer o󰀨 the Drive Belt Pulley, Drive Belt damage, or Drive Belt failure.
1.4.1 Drive Pulley Spacing
To check Drive Pulley spacing, use a Vernier caliper to measure the distance from the inside
of the Drive Pulley to the X Axis motor mount surface. The distance should measure ⅜ in. or
.375 in. A slight di󰀨erence in measurement is acceptable but it should be close to the specied
measurement.
Ensuring the Drive Belt is mounted on the machine correctly and tensioned correctly is
important to the operation of the Trolley.
