Abbreviated Instructions

Demounting & Mounting Toyota

tire/wheel with extended hubs using a

COATS Rim Clamp Tire Changer

Prevent accidents and injury, read and

follow all safety instructions. Always read

the entire operators manual for detailed

safety and inflation information when

using any tire changing equipment.

CAUTION: This wheel is difﬁcult to

service due to extended hub on

mount side.

Always review nicks and scratches with owners of

these wheel and tire combinations prior to servicing.

1. Deﬂate tire completely by removing the valve

core from the valve stem.

1.1 Position the valve stem at the bead loosener on

the front side as shown; this tire will only loosen ﬁrst

at this position because of the rim style (see below)

which is assymetrical.

Note: Notice the two features of the wheel, the short

side and the drop center. All tires are removed from

the short side of the wheel. Before the tire can be

removed a portion of the bead must be in the drop

center; this allows the opposite side bead to be moved

over the outside ﬂange of the rim.

Note: The wheel on the right has a typical short side,

however, the wheel on the left has an extended short

side that makes this tire very difﬁcult to install or

remove. Take time when mounting or demounting the

top tire bead.

3. The back tire bead is also loosened ﬁrst at the

valve stem.

4. Only allow the bead loosener to push the bead

over the safety bump on the rim.

5. To prevent wheel slippage, always outside clamp

this wheel.

6. Position the duckhead®near the rim and apply a

lot of lubrication.

7. The area to lubricate is the shoulder just adjacent

to the the drop center on the top side.

8. Before inserting the bead lift tool for top bead

removal, make sure the valve is positioned as shown.

This eases the effort to pull the bead up and over the rim.

9. Lubricate the lift tool and insert the end between

the tire bead and rim; apply downward force to engage

the tire bead.

10. As the bead is pulled up and over the duckhead

and onto the rim, assure the bead opposite the duck-

head is in the drop center. Use a tool or helper arm as

shown.

11. Once the top bead is in position over the duck-

head for removal, you may remove the lift bar to

reduce stresses in the tire. Proceed with removal by

jogging rotation to prevent damage.

12. To remove the second bead, use a second per-

son to hold up the opposite side bead in the wheel’s

drop center or use Robo Arm to assist.

Mounting

This information must be read and followed carefully

to prevent accidents and injuries during mounting.

Check tire and wheel carefully before

mounting. Make sure the tire bead diameter

and wheel diameter match exactly. Consult

the Rubber Manufacturer’s Association for

approved rim widths for tire sizes.

Attempts to force a bead seat on mis-

matched tires and wheels can cause the tire

to violently explode, causing serious per-

sonal injury or death to operator and/or

bystanders.

Never mount a tire and wheel handed to

you by anyone without checking both tire

and wheel for damage and compatibility. Be

extra cautious of persons without knowl-

edge of tire service. Keep by-standers out of

service area.

Never mount a damaged tire. Never mount

a tire on a rusty or damaged wheel.

Damaged tires and/or wheels may explode.

If you damage the tire bead during mount-

ing, STOP!, remove the tire and mark it as

damaged. Do not mount a damaged tire.

1. Lube tire beads and inspect for any tire damage.

2. Lubricate ledge on rim and inspect for damage.

3. Lube rim, as shown, and inspect for tire size,

match, and rim or tire damage.

4. Mount the ﬁrst bead.

5. Before beginning the top bead mounting, a useful

tool will be one or two lashing straps about four feet

long. These can be purchased at a hardware store or

can be suitcase type straps. They will be very handy in

preventing the tire from riding UP as it is being

mounted.

6. To begin the mounting process of the top bead, it

is necessary to stage several conditions.

Robo Arm Machine (Figure - A1)

A. Position the tire valve at 90 degrees ahead of the

duckhead (6:00 o’clock).

B. Secure a strap around the tire and rim at the (9:00

o’clock) position.

C. Position the Robo Arm at 7:00 o’clock as shown.

D. Position the lift bar as shown to assure the top

bead stays under the duckhead.

Non-Robo Arm Machine (Figure - B1)

A. Position straps at the 11:00 o’clock and 7:00

o’clock position.

B. Use two lift levers as shown to assure the bead

stays under the duckhead and in the drop center.

7. Rotate the table about 30-45 degrees.

8. Stop.

9A. On the Robo Arm machine remove or loosen

the strap, use a second lift bar to assure the bead stays

under the duckhead.

9B. On the Non-Robo Arm machine remove or

loosen the strap near the duckhead and reposition the

lift bars to assure the bead is under the duckhead and

the bead is in the drop center of the wheel.

10. Rotate the tabletop another 45 degrees.

11A. On the Robo Arm machine remove the strap

and assure the bead is in the drop center.

11B. On the Non-Robo Arm machine remove the

remaining strap and assure the bead is in the drop cen-

ter.

12. Rotate the tabletop another 45 degrees.

13. Note that the bead lock on the tire is now at the

12:00 o’clock position. Rotate the table very slow and

the tire will move over the rim ﬂange into position.
