Gobo Gear Planet Alignment

Each gear of the gobo wheel assembly must be aligned so that the gobos will index correctly. Use the
following procedure to re-align the gears in the event the gobo wheel is disassembled.
To re-align gobo gears:
Step 1. Place center (sun) gear at starting point so that timing mark is directly facing Position 1
(open) as shown in
Step 2. Set Position 6 planet gear as follows:
Step 3. Rotate center gear clockwise until timing mark is directly facing Position 6.
Step 4. Lift edge of center gear slightly (so that it will not turn), while at same time rotating Position
6 gear until timing mark is directly across from center gear timing mark. Lower center gear
into place and verify alignment.
Step 5. Set remaining planet gears by following same procedure. When all gears are aligned, rotate
center gear in full rotation to verify alignments and to verify that assembly spins freely.
When rotating, marks should align perfectly at each gear as they pass. Adjust as necessary
and recheck. There should be no drag in the movement.
