1.2.3 Reassembling the FNC nozzle assembly.
1
Reassemble the FNC nozzle
assembly.
1. Open the [Unit]-[Head] tab screen and
press the [Head] button to lower the
head to which you are reassembling the
FNC assembly.
2. Rotate the R-axis belt so that the spline
shaft is positioned where the FNC nozzle
assembly can be easily reassembled,
and then set so that the inscribed mark
in the middle of the index holder faces
the front.
3. Hold the FNC nozzle assembly with the
cutout facing towards the front and Type
202F nozzle pointing downwards, and
insert it into the FNC head until the FNC
lock pin inside the index holder is slightly
raised.

assembly up, insert the bevel gear and shaft
into the center hole of the FNC nozzle
assembly from the front, and align the mark
on the bevel gear with the mark on the
index holder.

CAUTION
Reassemble the nozzle assembly, bevel gear and shaft
in their original combination for each FNC head, without
mixing them with parts for other heads. If this
combination is changed, the bevel gear may not rotate
smoothly or the pickup vacuum level may degrade.

Secure the FNC nozzle assembly.
1. Turn the R-axis belt so that the bevel gear
faces the opposite side.
2. Align the flat surface on the bevel gear
shaft horizontally and insert the stopper
block from the side.
3. Open the [Unit]-[Head] tab screen, and
press the [Head] button to raise the head
for which you have just reassembled the
FNC nozzle assembly.

CAUTION
• When tightening the stopper block screws, hold the
edge of the FNC assembly so it won't rotate.
The spline belt might otherwise slip on the gear teeth.
• The screwdriver bit size may slightly differ between
manufacturers. Use the screwdriver that matches the
recessed pattern on the screw head.
5. Affix a new black seal (KV8-M71RH-00X)
to the heads of the stopper block screws.
When this black seal is not available,
check that the black coating on the
screw heads does not come off and no
light is reflected. If light is reflected from
the screw heads, replace the screws with
new ones or black out the reflecting
parts with a magic marker.
Step 3-2
Secure the FNC nozzle assembly
Position the flat face of shaft horizontally.
Insert the stopper block from the side.

Check the movement after
reassembly.
1. After reassembling the FNC nozzle
assembly, press the [Head] button on the
[Unit]-[Head] tab screen to lower the
reassembled head.
2. Lower the FNC lock pin cam.
Lowering this cam releases the FNC lock
pin, allowing you to rotate the bevel
gear by hand.
3. With the cam still lowered, check that
rotating the larger bevel gear also
rotates the smaller bevel gear smoothly.
