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 alignment mark is directly
facing Position 1 (open) as shown in Figure 2-13 .
Step 2. Set Position 6 planet gear as follows:
a. Rotate center gear clockwise until alignment mark is directly facing
Position 6.
b. Lift edge of center gear slightly (so that it will not turn), while at same
time rotating Position 6 gear until alignment mark is directly across from
center gear alignment mark. Lower center gear into place and verify
alignment.
Step 3. Set Position 5 planet gear as follows:
a. Rotate center gear clockwise until alignment mark is directly facing
Position 5.
b. Lift edge of center gear slightly (so that it will not turn), while at same
time rotating Position 5 gear until alignment mark is directly across from
center gear alignment mark. Lower center gear into place and verify
alignment.
Step 4. Set remaining planet gears by following same procedure. When all gears are
aligned, rotate center gear in full rotation to verify alignments. When
rotating, marks should align perfectly at each gear as they pass. Adjust as
necessary and recheck.
Step 5. Install flange, pulley and three 4-40x5/16" PFB screws to secure gears in
place.
