4.2 PQ, FQ, and RQ Stroke Adjustment
1. Adjustments should be performed with the servo power OFF.
2. Use the low shaft (identified in section 3.16) to set the stroke of stations 2, 8, and 10.
3. With the cam at 200 degrees, clutch (1), and the low shaft clutch (2) should be engaged.

4. Set the stroke in the range of 0.30 to 0.35mm, (0.31mm is the ideal value). Note that the
stroke value will change when rotating the shaft; set the stroke at the point where the shaft
descends the least. When rotating the shaft, the stroke should not fluctuate by more than
0.05mm.

rd
Station Origin Position and Stroke Adjustment
1. This adjustment should be performed with the servo power OFF.
2. Move the low shaft to the 3
rd
station at 200 degrees.
3. Engage and align the 3
rd
station clutch (1) with the low shaft, by adjusting the position of
bracket (2):

4. To check that the clutch and low shaft are properly aligned, rotate the shaft, and measure the
difference in stroke when the shaft is at 0, 90, 180, and 270 degrees. Tolerance is 0.030mm.
5. Once the clutch is aligned within tolerance, proceed to set the 3
rd
station stroke.

6. Set the length of the third station rod, (located in the cam box at the rear of the machine), to
minimum. (figure 5)
Figure 5
7. With the cam at 200 degrees, set the 3
rd
station stroke within a range of 0.30 to 0.35mm, (0.31mm
is the ideal value). Set the stroke by turning the stroke-adjusting rod, (located at the rear of the
machine next to the PQ motor). (figure 6)
Figure 6
8. When setting the stroke, ensure that the adjustment nut (at the tip of the arrow in fig.6), is in the
center of the stroke-adjusting rod.
9. Once the stroke adjustment is completed, place the 3
rd
station origin jig, or the common jig, on
shaft A.

10. Taking care to ensure that the jig does not interfere with the adjacent shafts, bring shaft A to the
3
rd
station at 200 degrees.
11. Loosen the two 5.5mm hex bolts above the third station clutch (fig. 8).

12. Rotate the position of the clutch (1) until the 3
rd
station origin jig is parallel to the D axis. Use a
dial gauge on the D axis to measure the surface of the jig. (Tolerance: 0 +/- 0.01mm)
13. Having locked the two 5.5mm hex bolts, and secured the clutch angle, double check that the jig
is still parallel to the D axis. Do this by rotating the jig past the 4
th
station, then back beyond the
3
rd
station, and finally forward to mesh once again with the 3rd station at 200 degrees
