3.19 Shaft Measurement Check

The following procedure explains how to check various items on the nozzle shafts. These

measurements are required when carrying out adjustments in Chapter 5.

1. Set the Cam angle to 0 degrees.

2. Turn the 11

station place solenoid ON.

3. Using shaft A as the reference 0, measure the height of the shaft

flange (1) for all the shafts A to T. Measure with the cam at 200

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. Next, use spool A as the reference and measure the height of

spools A to T. Note that the height of the spool should be

measured when it is at the upper limit (2). Measure at 200

degrees. Push down on the flange slightly with a finger so the

position of the shafts remains consistent.

(Tolerance: < 0.15mm)

5. Next, measure the stroke of the 12

station. Measure at 200

degrees. Put the dial gauge in the center of the clutch underside

(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 0.03mm.

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 to 0.45mm.

7. For the adjustments that follow in Chapter 5, it is necessary to

establish the following three values:

1. Identifying the low shaft. (the clutch which pushes down the least)

2. Identifying the shaft with the average clutch stroke.

3. Identifying the shaft with the low spool valve.

3.20 Slider Height Adjustment for ST1, ST11

To set the slider height, it will be necessary to remove a shaft assembly. Choose any shaft other

than the “A” shaft for removal.

1. Move the shaft to be removed near ST11 and set the cam angle to 0 degrees. Place a

8mm spanner at position A and remove the 3mm socket hex bolt from the top of the

clutch. (fig. 38)

2. Remove the four retainers for the linear guide and disconnect the vacuum hose. Remove the

shaft assembly from the index unit.

3. With the Placing and Pick-up valves OFF, move the opening where the shaft was removed to

Station 11 and set the cam at 180 degrees. Check the flatness of the slider surface as

indicated in Fig. 39. (the flatness should be zero) Follow the same procedure for Station 1.

(Pick-up)

4. For stations 1 & 11, turn the cam to zero degrees and turn the placing solenoid ON.

Measure the slider height in relation to the cylindrical cam (with the cam at 10 degrees) as

illustrated in Fig. 40. (10 degrees allows sufficient clearance for the dial gauge)

Adjust the height of the slider for Stations 1 & 11 by adjusting the appropriate 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 1

and 11

station rods.

3.21 Station 1 Pickup Height Adjustment

1. Set the cam angle to 0 degrees and turn the 1st station pickup valve ON. (Y020)

2. Install a nozzle jig in nozzle holder, No.1. (fig.42) Set the cam to 175 degrees.

3. Loosen the cam lever stroke adjustment bolts and move the fulcrum (fig. 41) so the dial

gauge reads zero. (Zero indicates that the pickup height is 0.650mm.) The tolerance for

all shafts must be 0.65 +/- 0.05. (check all shafts)

4. After adjustment, go back and check that the slider height is within tolerance.

(0 +/-0.03mm)

Important

Whenever the pickup height is adjusted, the slider height must be checked again.

Adjust both the pickup height and slider height until they are both within tolerance.

Exercise extreme care when setting the pick-up height. Mis-adjustment can lead to

component cracking during pick-up.

3.22 Reattaching the Shaft Assembly

When the slider height adjustment has been completed, reattach the shaft in the reverse order as

it was removed.

1. Tighten the retainer installation bolts using a torque wrench as follows.

(Torque the top 3mm bolts to 2 N.m, Torque the bottom 4mm bolts to 4N.m)

2. Using the bar jig, re-install the shaft assembly 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.
