Activating the Bead Breaker
A
CAUTION
The bead breaker uses a long stroke and high force. Be careful not to damage or bend rim parts,
such as the flange butt weld, when using the bead breaker.
1. Turn on the hydraulic pump to activate the bead breaker.
2. Apply enough hydraulic pressure to the bead breaker to push the flange about 1/2-3/4 inch [13-19
mm] from the lip of the bead seat band.
3. If the bead breaker moves and is no longer vertical, readjust the ram adjusting screw. You must
release pressure before adjusting the screw.
4. Continue applying hydraulic pressure until the flange is
about 3/4-1 inch [19-25 mm] from the lip of the bead seat
band.
5. Place a nut or similar object between the flange and the lip
of the bead seat band. (See Fig. 5.)
A
WARNING
To prevent personal injury, lay the nut on the flange and slide
it into position with two screwdrivers. Do not put your
fingers under the bead seat band.
6. Release hydraulic pressure.
Continuing to Break the Tire Bead
1. Move the bead breaker away from the flange butt weld,
2-3 feet [0,5-1,0 m] from its present position.
2. Follow the steps in “Activating the Bead Breaker” above.
3. Continue advancing the bead breaker around the rim,
2-3 feet [0,5-1,0 m] at a time, breaking the tire bead.
4. Stop breaking the tire bead when you have moved the bead
breaker about 3/4 of the way around the rim. (See Fig. 6.)
A
CAUTION
To prevent damage to the rim, do not use the bead breaker
within 12 inches of the flange butt weld.
5. Apply enough pressure to the bead breaker to completely
break the tire bead.
6. Release the hydraulic pressure.
NOTE:
If you have gone all the way around the tire and the
tire bead does not break: Repeat the steps in “Activating
the Bead Breaker” and “Continuing to Break the Tire
Bead” above, with more hydraulic pressure.
Removing the Lock Ring and O-Ring
1. Stand inside the tire rim. Remove the lock ring with two
pry bars. Start at the split in the ring and then work the
tools around the ring. (See Fig. 7.)
2. Place a pry bar or screwdriver under the o-ring and pull it out from the groove in the rim. Cut the
o-ring with a knife to ensure that a new o-ring is used. (See Fig. 8.)
