FRONT WHEEL/SUSPENSION/STEERING
Place the wheel assembly over the center shaft and
use the correct size cone to keep the wheel centered
during operation.
Install the bottom hold down nut, bearing side
down, and finger tighten it so the wheel can rotate
freely during operation.
Failure to back out
the breaker shoe
two turns will cause
the shoe to scratch
the bead lock,
which may cause
the tire to leak.
Install the breaker arm assembly over the center
shaft and adjust the upper rim supports to fit the
outside rim diameter.
Install the top hold down nut and tighten it finger
tight.
Pull the leverage bar down so the breaker shoe is
just below the rim lip. Turn the crank to fully push
the breaker shoe between the tire bead and rim.
Once the shoe contacts the rim, back the crank out
two turns to allow the shoe to clear the rim's bead
lock.
Push down on the leverage bar to push the tire bead
over the bead lock. Use only short strokes on the
handle. While the shoe is still engaged, turn the
wheel as far as it will go between strokes as you
break the bead around the rim.
Remove the breaker arm assembly and flip the
wheel over. Install the breaker arm assembly, adjust
the shoe properly and break the other bead by fol-
lowing the above procedures.
Remove the tire from the rim using a tire changing
machine or tire irons and rim protectors.
