Operating Instructions

COATS PAX SYSTEM

9024 E-PAX &

9024E PAX Adapter

This manual is written for the tire technician that may not be familiar with the PAX System; therefore,
many individual steps are included such as flipping the tire over to perform most of the critical work
from the top side of the tire. This allows the tire technician to become familiar with the physical design
of the system and better understand the sequence of events required to complete a safe and suc­cessful PAX tire service.

Once the sequence and physical design is understood by the tire technician, he may accomplish
some of the operations without flipping the tire over; however, it is recommended to follow the instruc­tions for the first several times. Changing the same tire several times helps in understanding the
sequence but as is typical with conventional tires, a first tire is always much more difficult than one
that has been changed several times.

The tire manufacturer’s recommendations should always be followed when servicing a PAX
tire system; especially when installing the PAX gel to the inside of the tire.

: PAX gel is the lubricant supplied by the tire manufacturer and should not be con­fused with rubber lubricant. It is very important not to contaminate the PAX gel with rubber
lubricant. Rubber lubricant may allow the gel to reposition and create assembly balance issues.

CAUTION

2 • Important: Always read and follow the operating instructions.

Operator Protective
Equipment

Personal protective equipment
helps make tire servicing safer.
However, equipment does not take
the place of safe operating prac­tices. Always wear durable work
clothing during tire service activity.
Loose fitting clothing should be
avoided. Tight fitting leather gloves
are recommended to protect oper­ator’s hands when handling worn
tires and wheels. Sturdy leather
work shoes with steel toes and oil
resistant soles should be used by
tire service personnel to help pre­vent injury in typical shop activi­ties. Eye protection is essential
during tire service activity. Safety
glasses with side shields, goggles,
or face shields are acceptable.
Back belts provide support during
lifting activities and are also helpful
in providing operator protection.
Consideration should also be given
to the use of hearing protection if
tire service activity is performed in
an enclosed area, or if noise levels
are high.

Failure to follow danger,
warning, and caution instruc­tions may lead to serious per­sonal injury or death to
operator or bystander or
damage to property. Do not
operate this machine until
you read and understand all
the dangers, warnings and
cautions in this manual. For

200. Removing PAX
Tire & Support From
Rim

Read and understand the
complete portion of the
removal process prior too
servicing your first tire. This
will help prevent damage to
the tire and wheel.

Refer to the line drawing dia­gram (page 5) often to under­stand the sequence of
servicing.

200.

Deflate the tire completely
by removing the valve core from
the tire pressure sensor; this is a
special core and should not be con­fused with standard cores.

201.

Place the PAX tire to be
serviced with the back side of the
rim up. This is the large diameter
side of the tire.

202.

Next, position the center
post into the riser and twist clock­wise to secure the post to the
riser.

203.

From the centering cone
selection, select the cone that best
fits and centers the wheel.

204.

Place the locking nut system
over the center post and tighten
using a short extension, apply about
50 foot pounds of force.

205.

Rotate the upper arm roller
device over the tire and wheel and
place the edge of the large roller at
the intersection of the tire and
wheel. Start rotating the wheel and
apply a small amount of down
force to the roller to loosen the
bead from the rim and create a
small gap for the rubber lubricant
application. Make one complete
revolution.

206.

Continue to rotate the
tire/wheel and apply a liquid rubber
lubricant into the tire rim gap inter­section. Do this for one complete
revolution. Make sure the rubber
lubricant is in the groove all the
way around the tire.

CAUTION

10 • Important: Always read and follow the operating instructions.

207.

Continue to rotate the tire
and add the liquid rubber lubricant
into the tire rim intersection.
Continue to apply downward force
to the bead. The roller is used to
push the bead down until it pops
over its own ledge an into the rims
drop center portion.

208.

Note that the bead has
been forced over its ledge and is in
the rim drop center.

209.

Initial support ring loosen­ing helps in top bead removal.
Place the tapered roller into the
holder and position against the
support ring. Push the tire toward
the roller system to observe the
support ring.

210.

Apply medium downward
force against the support ring and
rotate the wheel one complete rev­olution. At this time pick a 45 to 90­degrees segment of the tire and
rotate the rim forward and back­ward; applying more force each
time. After several back and forth
operations, the retaining clips of
the support ring will disengage the
rim. Once one area of the support
ring has disengaged, continue with
the process until the rim is com­pletely disengaged from the rim.
Force the ring 1/2 to 1-inch toward
the front side of the tire.

211.

Flip the wheel and tire
assembly over and tighten the hub
nut.

212.

Rotate the upper arm roller
device over the tire and wheel and
place the edge of the large roller at
the intersection of the tire and
wheel. Start rotating the wheel
and apply a small amount of down
force to the roller to loosen the
bead from the tire and create a
small gap for the rubber lubricant
application. Make one complete
revolution.

213.

Continue to rotate the
tire/wheel and apply a liquid rubber
lubricant into the tire rim intersec­tion. Do this for one complete rev­olution. Make sure the rubber
lubricant is in the groove all the
way around the tire.

Ledge

Important: Always read and follow the operating instructions. • 11

214.

Secure one of the plastic
“rim protector bead lift aids” that
was supplied with the PAX kit or
from the new tire kit supplied by
the tire manufacturer. Observe the
plastic part and notice that a
depression exists on one side of
the flap portion.

The plastic part should be ori­ented in a direction that the slot is
toward the tire when installed.

215.

Observe the distance
between the rim and the tire;
should be about 1/4-inch gap to
insert the plastic aid.

216

. Stop the rotation of the tire
and place the end of the plastic
protector between the roller, rim,
and tire as shown. Make sure the
slot in the plastic flap is down
toward the tire’s sidewall.

To prevent injury, keep fingers
away from the roller tool as
plastic part is being installed.

217. Jog the rotation of the tire

allowing the plastic protector to
sandwich between the tire bead
and the rim flange. Note that the
flap rolls under the roller.

218. Continue to rotate the tire

until the plastic aid is in the 2
o’clock position. Swing the double
roller arm away from the tire and
rim. Move to the opposite side of
the machine. Secure the PAX tire
lifting tool and apply rubber lubri­cant to both sides of the tip. Insert
the tip into the slot of the plastic
aid. Use force to assure the lip of
the tool is under the tire bead.

219. With the tool in position,

rotate toward the center.

220. Hold at this position. Note

that the tire bead may not free
itself from the rim.

WARNING

12 • Important: Always read and follow the operating instructions.

221. While holding the lift bar

down, position the right-hand
tapered roller assist device near
the edge of the tire tread and apply
an upward force.

222. This upward force from

the roller should free the tire bead
from the rim.

223. With the bead completely

free of the rim, remove the plastic
aid.

224. Remove the tire/wheel

assembly and flip the assembly
upside down. Secure the wheel
with the hub nut.

225. Position the tire bead

against the support ring.

226. Position the tapered roller

near the support ring.

227. Rotate the assembly and

continue to push down with the
roller.

228. Continue to rotate and

push down until the support ring
and tire are separated.

229. Note that the separation

of the tire and rim has left the tire
trapped. The rim must be removed
from the riser to allow the tire to
be removed.

Important: Always read and follow the operating instructions. • 13

300. Support Ring
Removal From PAX
Tire - Using Machine
To Hold & Ovalize
Tire

Read and understand the
complete portion of the
removal process prior too
servicing your first tire. This
will help prevent damage to
the tire and wheel.

Refer to the line drawing dia­gram (page 5) often to under­stand the sequence of
servicing.

301.

To begin the removal of the
support ring from the PAX tire,
position the table top where the
clamps are midpoint of the PAX
roller tool.

302.

Position the bottom of the
PAX tire at the edge of the table
top and make sure the large diam­eter is facing out. Allow the table
clamps to engage the tire tread.
Move the tapered roller down to
intersect the tread.

303.

Note that the tapered
roller’s end flange has engaged the
tread toward the back side. This
position should hold the tire in
place.

304.

Apply a small amount of
rubber lubricant to the inside bot­tom sidewall of the small diameter
bead of the tire.

305.

Apply a small amount of
rubber lubricant between the 3
o’clock and 9 o’clock position.

306.

Push the lower part of the
support ring toward the back of
tire. Insert the regular lift bar over
the support and under the tire; all
the way to the back to the inside
sidewall of the tire directly under­neath the power roller.

CAUTION

14 • Important: Always read and follow the operating instructions.

307.

Apply a downward force
with roller system; the roller will
help force the lift bar down; guide
the top of the support ring to the
outside of the tire.

308.

Twist the lift bar up to start

the insert out of the tire.

309.

Move to the backside of the
tire/insert, place the end of the lift
bar inside one of the support ring
cavities and lever the ring out of
the tire.

310.

Continue the lever action
until the ring is free of the tire side­wall.

401.

Position the bottom of the
PAX tire at the edge of the table
top, allow the table clamps to
engage the tire tread. Move the
tapered roller down to intersect the
tread. Make sure the large diame­ter is facing out.

While at this position it is also
a good time to complete the PAX
gel application to the inside of
the tire.

402.

Engage the tapered roller’s
end flange near the front edge of
the tire tread.

403.

Use the roller system to
apply a downward force to the tire
tread as shown. This will ovalize
the bead opening of the tire.

405.

Apply a small amount of
rubber lubricant to the front side
beads between the 3 o’clock and 9
o’clock position.

406.

Grasp the insert with the
retaining rim clips (UP) and force
the support ring inside the tire.

500. Mounting PAX
Tire Assembly

Read and understand the
complete portion of the
mounting process prior too
servicing your first tire. This
will help prevent damage to
the tire and wheel.

Refer to the line drawing dia­gram (page 5) often to under­stand the sequence of
servicing.

501.

First, position the PAX rim
on the riser device with the small
diameter up.

502.

Install the center shaft into
the riser and twist clockwise to
lock in.

503.

Select the correct cone to
center the wheel and then place
the retaining nut on to the shaft.

504.

You may want to use a
cheater bar to assure the nut is
tight (50 foot pounds torque)
because the roller mounting sys­tem will apply significant force to
the edge of the rim to mount the
tire.

505.

If the tire pressure valve
sensor was removed, this should
be reinstalled with new gaskets.
Torque the retainer nut per the
manufacturer’s specification.

506.

Inspect the tire for any
damage paying close attention to
the beads. Inspect the wheel
closely for damage. Clean the
wheel and remove any light corro­sion or rubber. Verify size match
between tire and wheel. Do not
attempt to service a heavily cor­roded wheel.

507.

Verify that the support ring
retention clips are near the outside
(small bead diameter side) of the
tire to intersect with the rim
groove.

CAUTION

Clips

508.

Apply a small amount of
rubber lubricant to the inside of the
support ring.

Remember to use only a small
amount of rubber lubricant as
it can contaminate the PAX
gel, which can affect tire bal­ance.

509.

Apply a small amount of
rubber lubricant to the large tire
bead diameter to assist when mov­ing it to the outside of the rim on
the bottom side.

510.

Place the tire and support

ring over the rim and push down.

511.

Bring the upper PAX arm
over the tire and position the dual
roller with the wide roller down.

512.

Position the roller with

some surface over the rim’s flange.

513.

Rotate the wheel/tire
assembly. Press down with the
roller. May take two to three revo­lutions. Stop when the support ring
is about 1/2-inch below the rim
flange.

514.

Crouch down in front of the
machine (6 o’clock position). Insert
two short lift bars between the tire
and rim close together. Note that
the entire lower tire bead should
be in the rim’s drop center before
attempting to flip the bead to the
outside of the rim.

As noted in 509, a small amount
of rubber lubricant applied to the
outside edge of the tire will help in
maneuvering the tire bead to the
outside of the rim.

515.

Separate the two bars 8 to

10-inches.

516.

Fold the two bars inward to
disengage the lower bead from the
rim.

CAUTION

Important: Always read and follow the operating instructions. • 17

18 • Important: Always read and follow the operating instructions.

517.

Move back to the top of the
rim. Rotate the dual roller for the
large roller to be down.

518.

Reposition the tire to move
it toward the roller. Push on tire
tread opposite the roller.

519.

Position the roller to the
outside edge of the rim to push the
support ring into position. Next,
position the upper tire bead on the
tire bead guide supporting the
large diameter roller.

520.

Apply a light lubrication to
the top bead to allow the tire to
float over the rim as the support
ring is pushed into location.

521.

Rotate the wheel and apply
a down force after each revolution.
Use the valve as a guide, only
apply force after a complete revo­lution.

522.

Continue to rotate and
apply additional force after each
revolution. To engage the retainer
clips of the ring into the rim may
take several revolutions of the
wheel.

523.

As the support ring is
pushed near location, the tire must
be held upward at the location
opposite the rollers, to prevent the
roller system from grabbing the
tire sidewall.

524.

In most cases, when the
small roller contacts the rim flange,
the support ring is located cor­rectly.

525.

Loosen the tire/rim assem­bly from the center post and flip
the assembly over.

526.

With the back side of the

wheel UP, tighten the hub nut.

Important: Always read and follow the operating instructions. • 19

With the tire/rim inverted,
position the tire and observe
that the support ring is
against the support ring stop.
Inspect at a minimum of three
positions.

527.

Apply a small amount of
lubrication to the bead area of the
tire.

528.

Reverse the position of the
dual roller, wide roller against rim.
Apply a small amount of down
pressure.

529.

Position the bead lock assist
tool about 6 to 8-inches right of the
roller.

530.

Rotate the tire/rim about
180 degrees and stop and observe
the bead mounting; if OK, apply
more downward force to the rim.

531.

Rotate the tire/rim another
90 degrees and stop, this gives the
bead time to relax and began to roll
into place. Rotate the tire/rim about
another 45 degrees and the bead
should snap into location.

532.

Once the bead is in posi­tion, twist the manual bead lock
device from the rim.

533.

Invert the tire/wheel so the

outside is UP. Tighten the hub nut.

534.

Apply small amount of rub­ber lubricant to the bead of the tire
making sure the rubber lubricant is
on the underside of the tire bead.
This bead rolls into place and the
rubber lubricant helps prevent any
bead damage.

535.

Position the small roller on
the rim and apply a moderate down
force.

536.

Place the manual bead lock
device onto the rim 6 to 8-inches to
the right of the roller system.

CAUTION

Note that support ring

is against “Stop Ledge”.

Slow

20 • Important: Always read and follow the operating instructions.

537.

Rotate the tire/rim about
180 degrees and stop and observe
the bead mounting; if OK, apply
more downward force to the rim.

538.

Rotate the tire/rim another
90 degrees and stop, this gives the
bead time to relax and began to roll
into place. Rotate the tire/rim
about another 45 degrees and the
bead should snap into location.

539.

Once the bead is in posi­tion, twist the manual bead lock
device from the rim.

600. Tire Bead
Positioning Before
Inflation Of PAX Tire

Once the tire is completely
mounted, bead positioning is
very important to assure the
tire balance remains consis­tent and does not reposition
after mounting on a vehicle.

601.

Begin by introducing 10 PSI

of air pressure into the tire.

602

. Bring the small roller down
to the edge of the rim and apply a
small amount of pressure. Rotate
the tire/wheel two complete revo­lutions. This should position the tire
bead to be concentric with the rim.

603.

Flip the tire over and repeat
the above (two complete revolu­tions).

CAUTION

Slow

Important: Always read and follow the operating instructions. • 21

604.

Note that any difference in
the concentricity between the tire
bead and the rim would signal that
the bead is not correctly position­ing onto the rim.

700. Configuring

TIRE FAILURE UNDER PRESSURE IS HAZ­ARDOUS! This tire changer Will Not Restrain
Exploding Tires, rims or other related equipment.

TIRES CAN EXPLODE, ESPECIALLY IF INFLATED
BEYOND SPECIFIED LIMITS. DO NOT EXCEED
TIRE MANUFACTURERS RECOMMENDED AIR
PRESSURE.

AN EXPLODING TIRE, RIM, OR BEAD SEATING
EQUIPMENT MAY PROPEL UPWARD AND OUT­WARD WITH SUFFICIENT ENERGY TO CAUSE
SERIOUS INJURY

OR DEATH TO OPERATOR

AND/OR BYSTANDERS.

DANGER

READ…

Mounting and inflating the
wrong size tire can get
you hurt.

Read

the size on
the tire and make sure it
matches the rim. Be espe­cially careful about putting
a smaller tire on a larger
rim, such as a 16-inch tire
on a 16.5-inch rim.

Inflation of a mismatched
tire and rim can cause an
explosion.

INSPECT…

Before you put any tire on
a rim,

inspect

the rim for
rust, tough spots, bent
edges, or cracks that could
prevent the tire from seat­ing right. If you spot any of
these problems, don’t
mount the tire until the rim
has been checked by your
shop foreman.

Inspect

the tire for bead

damage.

MOUNT…

Once you’ve made sure the tire is OK
and the right size and the rim is OK,

mount

the tire safely. NEVER, ever
lean over the tire when you’re inflating
it. If a tire does explode, it will go
straight up. You don’t want to be over
the tire if that happens. Also, never
over-inflate the tire, even if the bead
doesn’t seat. Never inflate over 40 PSI.
If the tire hasn’t seated, something is
wrong. Deflate the tire and check it
and the rim again. If it doesn’t work the
second time, try another tire.
