3.16 Shaft Measurement Check
The following steps explain how to check various items on the nozzle shafts. These measurements are
required when carrying out adjustments in Chapter 4.
1. Set the Cam angle to 0 degrees.
2. Turn the 9
th
station place solenoid ON. (Y035)
3. Using shaft A as the zero reference, measure the height of the shaft
flange (1) for all the shafts A to P. Measure with the cam at 180
degrees. Push down on the flange slightly with a finger so the
position of the shaft remains consistent.
(Tolerance: < 0.05mm)
Measure both ends of the shaft flange to ensure it is flat; the
difference between the two ends of the flange should be
0.01mm or less.
4. Use spool A as the reference and measure the height of
spools A to P. Note that the height of the spool should be
measured when it is at the upper limit (2). Measure at 180
degrees. Push down on the flange slightly with a finger so the
position of the shafts remains consistent.
(Tolerance: < 0.15mm)
5. Measure the stroke of the 10
th
station. (at 200 degrees) Put the
dial gauge on the under side underside of the clutch (3). Find
the lowest shaft (the shaft that pushes down the least) and set
the stroke for this shaft within the range of 0.3 to 0.35mm. Note
that 0.31mm is the ideal value. Also be aware that when rotating
the shaft the stroke amount will change; set the stroke where the
clutch underside is lowest. When rotating the shaft the
fluctuation in the stroke amount should be less than 0.05mm.

6. As mentioned above, the stroke of the lowest shaft should be
within the range of 0.3 to 0.35mm. The stroke of all the other
shafts must be within the range 0.3 (Min) to 0.45mm.(Max)
7. Measure the position spool valves A to P (4) in the X- direction.
Tolerance: within 0.1mm. If out of range, loosen the two
screws on the valve and reposition. (Torque = 0.8N.m)
8. For the adjustments that follow in Chapter 4, it is necessary to identify
the following three shafts:
1. Finding the low shaft.
2. Establishing the mid shaft. (Average deflection)
3. Finding the shaft with the low spool valve.
4. Finding the shaft with the highest spool. (used for station 13 adjustment)

3.17 Slider Height Adjustment for ST1, ST9
To set the slider height, it will be necessary to remove a shaft assembly. Choose either the G or
O shaft for removal, as these are the only two points open enough to make the measurements.
1. Move the shaft to be removed near ST9 and set the cam angle to 0
degrees. Place a 7mm spanner at position A and remove the 2.5mm socket
hex bolt from the top of the clutch.
2. Remove the four retainers for the linear guide and disconnect the
vacuum hose. Remove the shaft assembly from the index unit.
3.17.1 Adjusting the slider height
Note: The following procedure for CP-7 series machines is the same,
(except for the 9
th
station on CP-742/743(M)E which is written
in step 3.17.2.)
1. With the Placing and Pick-up valves OFF, move the opening where the
shaft was removed to Station 9 and set the cam at 180 degrees. Check
the flatness of the slider surface as indicated in Fig. 48. (the flatness
should be zero) Follow the same procedure for Station 1. (Pick-up)
2. For station 9, turn the cam to zero degrees and turn the placing solenoid ON.
Measure the slider height in relation to the cylindrical cam as illustrated in Fig. 49.

Adjust the height of the slider for Station 9 by adjusting the 9
th
station rod in the Cam Box.
After adjustment, rotate the cam a few times and return to check the value again. Once
complete, ensure the lock nut is securely tightened on the 9
th
station rod.
Figure 47
3. For station 1, turn the cam to zero degrees, turn the Pick-up solenoid ON and make sure the
NZ axis is set at the minus mechanical stopper. Measure the slider height in relation to the
cylindrical cam as illustrated in Fig. 49.
Adjust the height of the slider for Station 1 by adjusting the bolts shown in Figure 50. After the
adjustment rotate the cam a few times and return to check the value again. Once complete,
ensure the lock nut is securely tightened on the 1
st
station slider bracket.

2. If step 1 fails, loosen

slider. After completion,
ensure the nut is securely
tightened.

3.17.2 Adjusting the 9
th
station slider for CP-742/743(M)E
1. Remove shaft G or O to gain access to the 9
th
station slider.
2. Turn the cam to 0 degrees and turn the placing solenoid valve ON. (Y035)
3. Adjust the slider height, so the leading edge top surface between the cylindrical cam and slider is
smooth to the touch. (See Fig. 51) Or use a dial gauge as indicated in Fig. 52.

4. Adjust the height using the 9
th
station adjustment rod in the cam box. After completion, rotate the
index and return to check the position. If OK, then make sure the lock nut is tight on the rod.
3.18 Reattaching the Shaft Assembly
When the slider height adjustment has been completed, reattach the shaft in the reverse order
removed.
1. Tighten the retainer installation bolts (M4 x 12 ) using a torque wrench:
Torque value: 1.96N.m (20Kgf/cm)
2. Using the bar jig (at station 9), re-install the shaft assembly (with the cam at 180 degrees) and
align the holder and clutch so the alignment jig inserts smoothly between the holder and the
clutch. (there should be NO resistance) It is important for all shafts and clutches to be aligned
properly in order to avoid problems later on.
