3. Set a dial indicator on the FRQ cam lever (Station 12). Make sure that when the cam lever is at
the low point, the cam axis is between 107 and 267 degrees.
4. After checking the above, ensure the A-axis scale matches the B-axis reference scale.
Notes:
1. In all cases above, the maximum difference between the stopping and starting points
should be within +/- 1 degrees.
Example: If the nozzle index stops at 122 degrees it should begin moving at 254 +/-
1degree.
2. The exact timing of movement varies a little from machine to machine. (but still within
tolerance). The main point is to ensure that the stopping and stating points are
balanced.
2.6 Helical Gear Backlash Check
1. Check the backlash of the large helical gear using a dial indicator with shafts A, F, K, and P at
station 11. (180 degrees)
2. The backlash between the two helical gears should be within 0.030 to 0.080mm.
3. The backlash may be adjusted by moving the theta index unit to the right or left.

2.7 3st PQ and 13st PRQ Cylinder Rod Adjustment
1. Release the air and make sure that the cam follower is in contact with both sides of the barrel
cam when the angle is at 257 degrees. If not, adjust the stroke of the cylinder rod end.
2. Set the air regulator in the cam box to 0.4MPa. Tighten the lock nut and mark with a white
marker.
3. Check each cylinder sensor. The sensor must turn ON when the cam angle is between 210 to
212 degrees. (Ensure that the cam follower moves to the right when both PQ and PRQ rotate
90 degrees, and moves to the left when rotated 270 degrees.)

2.8 Cam Lever Stopper Adjustment
1. Adjust the Cam lever stopper at stations 1, 3, 10, 11, 13
and 18.
2. Turn each station’s solenoid valve ON at zero degrees.
(The cam will be in contact with the cam roller when the
solenoid valve is ON, and apart when the valve is OFF.)
3. Set a dial gauge on the cam lever to measure the
clearance at each valve location.
4. When the solenoid valve is OFF, adjust the air cylinder
stroke so that the dial indicator reads within the ranges
shown below.

2.10 Cam Axis Origin Flag Adjustment
1. Set the cam angle to zero.
2. The center of the dog must align with the center of the sensor at cam 0. (0±1 degree)
Note: If the flag is centered, the sensor should turn OFF at 5 degrees on either side of 0.
