[1] Replacement of Main Motor Bearings
Before proceeding to the motor replacement work,
be sure to turn off the main power switch.
[1.1] Replacement Interval and Bearing Types
(1) Replacement interval
Replace bearings 1 and 2 approximately once
every three years (24 hours/day as operation
hours).
If the environment contains excessive dirt, dust,
or fly, or if the motor temperature is high due to
excessive tension of the V belt, then grease may
deteriorate and flow out.
Based on these conditions, make the replacement
intervals shorter.
NOTE: The special bearings are adopted for
bearing 1 and 2 of the main motor.
Ordinary bearings (prelubricated with
Arbania No.2 or its equivalent) shall not
be used since they will shorten the
bearing service life.

(3) Braking operation
1.The brake always works while the weaving
machine is on halt after powering up.
2.Pressing the START switch or the inching
switch (FORWARD or REVERSE) cuts off
the braking power so as to degauss brake yoke
10 so that attracted armature 11 will be
retracted to the normal released position with
the attached leaf spring. Accordingly, the
brake will be released.
3.Power is applied to the main motor and the
machine starts running.
4.If the control box receives a stop signal, it cuts
off the motor power. At the same time, brake
yoke 10 is magnetized and attracts armature
11 to the shaft with more force than the
spring.
5.As a result, armature 11 is pressed against the
lining, whose frictional force generates
braking torque so that the motor quickly stops.

[1.3] Removal of Motor
(1) Without Brake
■ Removal procedure
1.Turn the machine power off.
2.Disconnect 11, 12, 101, and 103 wires
from the terminal board, U, V, W, X, Y,
and Z wires from the contactor, and E
(earth) wires from the grounding terminal
board in the control box.
NOTE: The two E wires should be discon-
nected at the last.
3.Remove the main motor from the weaving
machine and place it on the workbench.
■ Procedure of replacing bearings
1.Remove bolt 1 and take out outer cover 2.
2.Pull out fan 3.
・Key 4 of the aluminum-made fan is fixed
with an set screw.
Loosen the set screw to remove.
・Adhesive is applied to key 4 of the resin-
made fan.
Melt the adhesive with hot air and detach
it.
3.Remove bolt 5 and detach bracket 6 from
the body of the motor.
4.Remove the dust and fly that are attached to
parts with friction-powder compressed air.
5.Remove bearing 8 of shaft 7.
6.Reinstall the removed components with the
reverse order of the above steps.
NOTE:
・Make sure that all screws are not loose.
・Fasten bolt 5 with torque of 15N·m-
16N·m (150-160kg·cm) .
・Apply Three Bond 1322 to the set screw
at the area where the aluminum-made
fan is fastened.
Apply Aron Alpha #203 to the center of
the key slot of the resin-made fan.

M.2-4
(2) With Brake
■ Brake adjustment (option)
The initially set gap “a” between armature 1
and brake yoke 2 is 0.3 ± 0.05 mm. If the
gap “a” becomes wide, the attraction force
of the brake yoke for the armature weakens
when the brake is activated, so that the
timing from powering-off to machine stop
will drag out.
Accordingly, the stop position of the
machine will be beyond the specified
position.
In such a case, adjust the gap “a” with the
steps below:
■ Procedure of replacing bearings
1.Remove screw 1 and then outer cover 2.
2.Remove bolt 3 and then fan 4.
3.Remove bolt 5 and washer at the end of the
shaft and then pull out brake hub 6.
4.Remove key 7 from the shaft and pull out
shim 8 (2 pieces of thin plate, 1 piece of
thick plate, and 1 piece of collar).
5.Remove bolt 9 and then detach brake stator
10 from the main body of the motor.
NOTE: Be sure not to misplace wave spring
11.
6.Remove the dust and fly that are attached to
each part with friction-powder compressed
air.
7.Remove bearing 13 of shaft 12.
8.Reinstall the removed components with the
reverse order of the above steps.
NOTE:
・Make sure that all screws are not loose.
・Fasten bolt 7 with torque of 15N·m-
16NÅEm (150-160kg·cm) .
・Apply Three Bond 1322 to bolt 5.
・Adjust the gap as [0.3 ± 0.1]mm by
adjusting the position of the brake hub
using the *-marked shim.

[1.4] Replacement of Bearing
(1) Removing the bearing
1.With a press
Support the rotor 1 with inner ring 2a of the
bearing 2, then press shaft end A with a press
to take out the bearing.
2.With pull-out tools
・With a pulley pull-out tool commercially
available:
Hook pawls 3 onto inner ring 2a of the
bearing 2, then rotate handle 4 to take out the
bearing.
・With a special tool:
Make a special box tool, set shaft-box cover
5 against inner ring 2a of bearing 2, then
rotate handle 6 to take out the bearing.

M.2-6
(2) Reinstalling the bearing
Before reinstalling the bearing, apply oil to the
joint between the bearing interior and the motor
shaft.
NOTE: Set the bearing over the shaft perpendicu-
larly.
1.With a press
Apply pipe 7 having the same diameter as the
distance of inner ring 2a of bearing 2, to the
inner ring. Then, force-fit the bearing gently
with a press.
2.Without a press
Apply a pipe jig having the same diameter as
inner ring 2a of bearing 2, to the internal ring.
Then, drive in the bearing by tapping section
B gently with a hammer.
NOTE: Take care not to twist the bearing or let
the pipe jigs touch the seal and outer ring
of the bearing.
[1.5] Installation of Motor
(1) Install the main motor having new bearings onto
the machine.
(2) First, connect the two E (earth) wires to the
grounding terminal.
(3) Connect wires 11, 12, 101, and 103 to the
terminal board, then wires U, V, W, X, Y, and Z
to the contactor.
(All of these wires were disconnected in “■
Removal of Motor” procedure.)
(For towel weaving machines, connect wires U,
V, and W only to the contactor.)
■ Motor rotation direction and belt tension
Refer to Chapter 1, Subsections 1.1.3 and 1.1.4.

[2] Adjustment of Separate Brake
■ Adjustment of brake section
The initially set gap “a” between armature 1 and
brake yoke 2 is 0.5 ± 0.1 mm. If the gap “a”
becomes wide, the attraction force of the brake yoke
for the armature weakens when the brake is
activated, so that the timing from powering-off to
machine stop will drag out.
Accordingly, the stop position of the machine will
be beyond the specified position.
In such a case, adjust the gap “a” with the steps
below:
(1) Move the brake yoke fixed by four W-nuts (Nos. 1
through 4) shown by arrows in the figure to adjust
gap “a” of the separate brake.
(2) Adjust W-nuts so that gap “a” is 0.5 ± 0.1 mm.
(3) Put 0.5 mm shims equally on four sides between the
stator and armature, adjust the stator position with
the brake applied, and ensure gap “a”.

[3.1] Air Filter
(1) Shut off the compressed air with cock 1.
(2) Turn cock 3 provided on the bottom of bowl 2
clockwise to release the residual pressure.
Expel air from the main and sub tanks. (This
operation is the same as for draining.)
Be sure to release the residual pressure at this
stage. If you proceed to steps (3) and (4) without
releasing it and attempt to remove bowl 2, the
residual pressure will blow off bowl 2 with a
powerful blast. It is dangerous.
(3) While supporting air filter plate 4 with your right
hand, hold bowl 2 with your left hand and press
the lower section of latch 5 with your left thumb.
(4) Turn bowl 2 clockwise until mark △ A on latch 5
is aligned with mark △ B on air filter plate 4,
then pull down bowl 2.

■ Replacement procedure for the electromagnetic pin and the plunger cap
The procedure below requires hot water of 95°C
to soften glue. Be sure to wear the protector
during this job.
Organic solvent and glue contain highly flamma-
ble ingredients. Keep them from fire to prevent

[3.6] Valve Disassembly, Cleaning and Assembly Procedure
M.2.1 Main Motor Bearings, Weft-insertion-related Components,Selvage-forming-related Components, Reed, and EDPCeramic Piece
M.2-22
As a principle, replace the valve in the following
procedure when you find it faulty through inspection.
Frequency may differ by the conditions of the usage,
however, the bi-annual overhaul and the cleaning of
the valves are recommended for further safe and proper
use.
Concerning the exhaust valve of the sub valve, annual
overhaul is recommended.
Furthermore, if using the sub double blow function, it
is recommended that the sub-valve be overhauled
approximately once a year.
The following three components of the plunger block
shall be maintained with due care to keep the valve in
good condition.
・Guide rings ⑤ (GUIDE)
・Urethane seat (SEAT)
・Poppet (VALVE, POPET)
Replace the guide rings when their outer diameter is
reduced to 10.7 mm or smaller.
Replace the urethane seat when thinned down to 0.7
mm or less to avoid the end face come in contact with
the metal.
Replace the poppet if the valve has more backlash, or if
the seating surface is worn to cause air leak.
Especially, the guide rings of the cut blow valve may
wear out quickly due to the conditions of the air and
other factors. This valve is located outside the frame
and thus easy to maintain. Perform the maintenance of
the valve at least once a year.
At replacing the guide rings or urethane seats, it is
recommended that the springs are replaced as well.
Abrasion powder may be generated when the spring is
used for a long period, and such usage may accelerate
the abrasion of the parts such as guide rings.
In addition, the guide ring for the exhaust valve of the
sub valve may be worn out quickly according to the
conditions of the air.
Maintain valves at least once a year preferentially.

[5] Cleaning of Reed
Since the reed wind pressure is changed by the oil of yarn during weaving with filament warp, cleaning the reed at every
warp-beam change will stabilize picking.
The contaminated reed may adversely affect the quality of any woven fabric and the operation rate of the machine;
therefore, be sure to clean the reed before it is stored or reused. When the dent material is SUS420J2, the dent must be
cleaned periodically to prevent corrosion (rust) caused by contamination.
[5.1] Cleaning the Reed on the Machine

tool handle.
3.Press the emergency stop button down until it
locks itself and the machine.
4.For reflecting weft feelers (for non-cut reed),
cover each of the weft feelers 1 with caps 2.
For penetrating weft feelers (for cut reed),
take out the weft feelers from the machine. (If
the reed cleaner adheres to the penetrating
weft feelers, the feeler's sensitivity will
diminish.)
5.Put rods 4 on warps 5 at the front and rear of
reed 3 to lower warps 5.
NOTE: Take care not to break warps.
6.Put some sort of shield 7 between healds 6 and
reed 3 over the full width.

[7] Replacing the Inverter’s Capacitorsand Cooling Fans
(1) Smoothing capacitors
The smoothing capacitors for the inverter should be replaced with new spare capacitors every 5 years due to the
service life.
It is recommended that you place an order for the spare capacitors when the replacement time is close. This is
because capacitors stored more than 3 years require aging before use and the aging is difficult at your site.
(2) Electrolytic capacitors
The electrolytic capacitors on the inverter board should be replaced every 5 years.
It is recommended that you set up a spare inverter board when the replacement time is close, replace the inverter
board with the spare, and send it to TOYOTA for repair.
For the details about the inverter replacement parts, refer to the instructions manual issued by the inverter
manufacturer.
(3) Cooling fans
In the inverter box are cooling fans which should be replaced at the intervals of 2-3 years as a unit of complete
assembly due to the service life of bearings used.
NOTE: For details on the inverter replacement parts, refer to the instruction manual provided by the inverter
manufacturer.

M.2.2 Blower Motor(for Filament or Glass Fiber)
Be sure to check that the main switch is turned
OFF before connecting the blower motor leads.
■ Tightening torque of blower motor leads
When connecting the blower motor leads to the
terminals inside the terminal box, tighten the
mounting nuts to a torque of 0.8 to 1.2 N·m (8 to 12
kgf·cm).
Applying excessive torque may break the terminal
board.

M.2.3 Replacement of Felt, FeltStopper, and Body
Bushing(Glass Specification)
(1) Hold the body Assy with a hand, set the felt
stopper/bushing removal jig, and drive the head of
the jig (shown by the arrow in the figure) with a
plastic hammer to remove the body bushing, felt,
and felt stopper.
(2) After removing the parts, blow air to remove foreign
matters completely.
NOTE: Carefully remove foreign matters thor-
oughly since insufficient removal may
adversely affect the performance.
(3) Set the body to bushing press-fitting jigs B and C.
With the chamfered side facing down, use press-
fitting jig A and press-fit the body bushing onto the
body.
At the time of pressing in, align the upper face of the
body bushing with the [X] plane. Since rapid
pressure application may deform the inside diameter
of the body bushing, use a hand press or the like to
apply pressure gradually for press-fitting.
After pressing in the body bushing, blow air to
thoroughly remove foreign matters and apply
CRC3-36 on the inside surface of the body bushing.
M.2.3 Replacement of Felt, FeltStopper, and Body Bushing(Glass Specification)
M.2-47
(4) Replace jigs with bushing press-fitting jig C and felt
stopper press-fitting jig E. Set the body with
bushing. With the chamfered portion of the felt
stopper facing down, press in the felt stopper using
felt stopper press-fitting jig D onto the body.
At the time of press-fitting, set the upper face of the
felt stopper (0 to 0.5 mm) below the [Y] plane. If
press-fitting is insufficient (above the [Y] plane), the
felt stopper may be caught by a yarn during loom
running to cause broken yarn or felt stopper
departure.
On the other hand, sudden pressurizing may deform
the felt stopper. Use a hand press for gradual
pressing.
After press-fitting the felt stopper, carry out air
blowing for perfect removal of foreign matters and
burrs.
REFERENCE:
Refer to Section G.2 “Tools” for the details of
jigs.
REFERENCE:
As for maintenance other than the felt and felt
stopper, refer to subsection M.2.1 [ 3.2 ].
