Troubleshooting Guide
Place the supplied ¾ in. thin wrench on the eccentric bearing adjustment hex located between
the Gate Mount Plate and the Gate Bearing Rotation Plate or Gate Ring Gear. Turn the
adjustment hex until the Gate Ring Gear bearing surface is fully seated in the eccentric bearing
v-groove.
When properly adjusted, the Gate Ring Gear should spin freely with no side play. Tighten the
v-groove eccentric bearing nut securely, ensuring the bearing stays in adjustment.
2.2.6 Re-install the Gate
Re-install the Gate. Use assistance in placing the gate. Ensure the eccentric bearing is to the
bottom of the Gate. Tighten the four bolts with a 9/16 in. socket and ratchet.
Important
Re-install the Parts Catcher, Beak, and/or Coolant Trays if they were removed to
access the Gate.
2.2.8 Position Drive Gear (Powered Gate Only)
Push the C-Axis Drive Gear onto the C-Axis motor shaft. Ensure it fully meshes at the center of
the Gate Ring Gear. The drive gear must be centered on the Gate Ring Gear.
Install each set screw and tighten securely with a 3/32 in. Allen Wrench.
2.2.9 Re-attach the Safety Guards (Powered Gate Only)
Re-install the Safety Guards.
2.3 Adjusting the C-Axis Backlash
Adjusting the C-Axis Backlash is only necessary on Dragon A400 machines equipped with a
Powered Gate.

Motor Mount. Set the screws and guard aside.
