Lubricate the bevel gear and shaft.
Using the lubrication syringe (KV8-M8870-
00X) and turbine oil (VG32), apply one drop
of oil at each of the bevel gear inner sides
and shaft, and then spread it with your
finger.

CAUTION
Do not lubricate the bevel gear section, as foreign
matter may get caught in the gear.
t
Reassemble the FNC nozzle
assembly.
Use the Phillips screwdriver to reassemble
the nozzles onto the nozzle block.

CAUTION
The screwdriver bit size may slightly differ between
manufacturers. Use the screwdriver that matches the
recessed pattern on the screw head.
Take care not to lose the small spring inserted in the
spring-action nozzle.

Precautions when replacing the bevel gear shaft (SHAFT_1)
Caution is required when replacing only the bevel gear shaft (SHAFT_1) during maintenance since a nozzle assembly and
SHAFT_1 must be used in the correct combination. There are 3 grades each of nozzle assemblies and SHAFT_1 depending
on the hole inner diameter and shaft outer diameter. They are identified by marks ( , , etc.) as shown below. Always
use the correct combination of a nozzle assembly and SHAFT_1 which have the same mark.
c
CAUTION
If the nozzle assembly and SHAFT_1 combination is incorrect, the nozzles may operate erroneously or vacuum leaks
may occur during component pickup.

1.2.3 Cleaning the FNC lock pin
Inside the spline shaft of each YG100RA FNC head, a lock pin (or locate pin) is used to lock the rotation of the
FNC nozzle assembly when the selected nozzle points downwards. If dust or grime adheres to this lock pin,
component pickup or mount errors tend to occur. Although depending on the operation time, we recommend
cleaning the lock pin at the time when you take apart and clean the FNC nozzle assembly.
1
Clean the FNC lock pin parts.
Wipe the FNC lock pin and spring with a
lint-free cleaning cloth moistened with
alcohol.
53377-F9-00
2
Clean the FNC lock pin insertion
hole.
1. Blow air into the air path of the FNC lock
pin insertion section of the spline shaft.
2. Wipe inside the FNC lock pin insertion
section thoroughly with a lint-free cotton
swab moistened with alcohol.
53379-F9-00
Reference
Use spiral-tip cotton swabs (thickness: 4mm or less) that
are commercially available.
3
Lubricate the FNC lock pin.
Using the lubrication syringe (KV8-M8870-
00X) and turbine oil (VG32), apply one or
two drops of oil to the FNC lock pin and then
spread it with your finger.
4
Reinstall the FNC lock pin and
spring.

1.2.4 Reassembling the FNC nozzle assembly
When finished cleaning the FNC nozzle assembly and FNC lock pin, reassemble them as explained below.
1
Rotate the spline shaft so the mark
in the middle of the index holder
faces the front.
53381-F9-10
2
Reassemble the FNC nozzle
assembly.
Insert, in order, the spring, FNC lock pin and
FNC nozzle assembly into the holder. At this
point, hold the FNC nozzle assembly with the
cutout facing towards the front and Type
212F nozzle pointing downwards, and insert
each part up into the index holder.

NOTE
Before inserting the FNC lock pin, make sure that the
small cams above the index holder are retracted
upwards.
3
Insert the bevel gear and shaft into
the center of the FNC nozzle
assembly.
While slightly pressing the FNC nozzle
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.
53354-F9-10
c
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 drop.
