Lubricate the bevel gear and shaft.

Using the lubrication syringe for nozzle

padding part and turbine oil (VG32), apply

one drop of oil at the inner side of bevel

gear and shaft respectively, and then

spread it with your finger.

53327-L1-10

CAUTION

Do not lubricate the bevel gear section, as foreign

matter may get caught in the gear.

Reassemble the FNC nozzle

assembly.

Use the Phillips screwdriver to reassemble

the nozzles onto the nozzle block.

CAUTION

Attach the nozzle where it was removed.

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.

CAUTION

If the nozzle assembly and SHAFT_1 combination is incorrect, the nozzles may operate erroneously or vacuum leaks

may occur during component pickup.

2.2.3 Cleaning the FNC locate pin

Inside the spline shaft of each FNC head, a locate 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 locate pin,

component pickup or mount errors tend to occur. Although depending on the operation time, we recommend

cleaning the locate pin at the time when you take apart and clean the FNC nozzle assembly.

Clean the FNC locate pin parts.

Wipe the dirt on the FNC locate pin and

spring with a cleaning cloth moistened with

alcohol.

53329-L1-10

Clean the FNC locate pin insertion

hole.

1. Blow air into the air path of the FNC

locate pin insertion section of the spline

shaft with the air blow tool (option).

2. Wipe inside the FNC locate pin insertion

section thoroughly with a spiral-tip cotton

swab moistened with alcohol.

3. After cleaning, check it is completely

clean.

53330-L1-00

NOTE

Wipe and clean to the end of the FNC locate pin

insertion section.

NOTE

Use spiral-tip cotton swabs (thickness: 4mm or less) that

are commercially available.

Lubricate the FNC locate pin.

Using the lubrication syringe for nozzle

padding part and turbine oil (VG32), apply

one to two drops of oil on the FNC locate

pin, and then spread them with your finger.

Reinstall the FNC locate pin and

spring.

2.2.4 Reassembling the FNC nozzle assembly

When finished cleaning the FNC nozzle assembly and FNC locate pin, reassemble them as explained below.

Rotate the spline shaft so the mark

in the middle of the index holder

faces the front.

53331-L1-00

Reassemble the FNC nozzle

assembly.

Insert, in order, the spring, FNC locate 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 302F nozzle pointing downwards, and

insert each part up into the index holder.

53332-L1-00

NOTE

Before inserting the FNC locate pin, make sure that the

small cams above the index holder are retracted

upwards.

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.

53333-L1-00

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.

Positioning so the mark faces the front
