Edition 6.0 Chapter 4. Station Adjustment [23/28]
4.22 Station 9 Mechanical Valve Adjustment Check
1. Remove the spool valve from shaft “A “and install the valve alignment jig.
Mechanical Valve Jig
Jig No. DGPJ6610
Note:
Place the dial gauge on the right side of the
“Low Valve” and set to 0. Remove the valve
and install the alignment jig at the same
position the valve was located. All valves
should be within 0.1mm of each other.
Refer to Sec. 3.16, page 3-32 step 6.

2. With the cam at 0 degrees turn the 9
th
station place solenoid OFF. (Y034)
3. Disconnect the air.
4. Move the cam angle to 195 degrees.
5. Loosen the forward and backward positioning bolts for the 9
th
station bracket.
6. Adjust the 9
th
station bracket so that the small round bracket notch goes directly into the jig hole.
You can check if it is properly inserted by moving the bracket. If it is completely inside, the
bracket will not move.

7. Once finished, remove the jig and reconnect the air at 0 degrees.
8. Turn the 9
th
station place solenoid ON (Y035) and install the spool valve on shaft A. Ensure the
spool valve is in the same position as the spool valve on the B shaft. (use the X-axis pulse
counter with the cam at 195 degrees and measure using a dial gauge.

9. Next, bring the shaft with the lowest spool to the 9
th
station at 195 degrees.
10. Set the gap between the spool and bracket to 0.1mm using a feeler gauge ( figure 36 above).
11. Set the flow controller as follows: For the rough adjustment of the flow controller, set 5 turns
from fully closed. For fine adjustment, set the cam at 195 degrees with the
highest valve at
station 9. Turn ON (I/O: Y03A Air Blow) Using a manometer, set the air pressure to 113+/-
3mmHg. (15.0+/-0.5 kPa)
4.23 Station 1 Mechanical Valve Adjustment
1. Adjust all shafts so that the gap between the spring pin BKT (1) top surface and support BKT
top surface is 2.3mm. (A) Note: all spring pin heights should be within 0.1mm of each other.

The spring pin height on shafts
A to P should be within 0.1mm.
2. Set the mechanical valve switch lever alignment as follows:
a. Adjust the clearance between the spring pin bracket and lever bracket using a 12mm
spacer jig. (figure 38). (Jig. No. ADCPJ8150)
b. Align the vacuum switching lever and mechanical valve as illustrated with the cam at 170
degrees. (figure 39).

3. Turn the station 1 pick up solenoid valve OFF (Y031) and move the reference shaft (the shaft
with the lowest spool position) to station 1 and set the cam to 170 degrees.
4. Adjust the lever BKT (2) so the clearance between the spring pin and lever becomes 0.6mm.

1. With the cam at zero degrees, turn the pick up solenoid valve ON. (Y031)
2. Set the NZ to its minimum stroke: (pick up pos. NZ-2619 pulses) and set the cam angle to
170 degrees. Check that the spring type pin (1) is pushed up slightly.
[Note]: Confirm that there is no interference when the NZ-axis is moved through full stroke.
