Company to facilitate step 3.
4. After the tire bead is unseated, stand on the
flange and tire side wall to depress the flange
down along the rim base; then, pry loose the
lock ring. Keep fingers out of the way.
5. Hold the side flange down with the hooked
end of a bead unseating tool and remove the
O-ring from the O-ring groove.
6. Remove the side flange. Turn tire and rim
over and unseat second bead by inserting
both bead unseating tools between the bead
and rim flange as in step 3. Repeat step 3
until the tire bead is completely broken loose
from the rim on the fixed flange side. Lift rim
base out of tire.
7. Refer to paragraph 5.1.11 for tire mounting

5.1.5 Demounting Tire from Single
Piece Wheel (S/N OF1192 & After)
IMPORTANT: Always completely deflate tire as
described in paragraph 5.1.1, before you attempt
to demount a tire.
1. Be sure you’ve read and understood the
warning notices and general instructions in
paragraph 5.1.
2. Place the wheel and tire assembly on the floor
on blocks with the narrow ledge on the bottom,
Fig. 5.3.
NOTE: A mechanical bead unseating and seating
tool may be purchased from the Iowa Mold Tooling
Company to facilitate step 3.
3. After deflating tire as described in paragraph
5.1.1, drive the hooked ends of two bead
unseating tools between tire bead and rim
flange about 5" (127 mm) apart; be careful that
you don’t damage the tire bead area. Pry both
tools down and out. Leave one tool in position
and place the second about 5" (127 mm)
beyond. Repeat the operation slowly, in
successive steps, until tire bead is completely
unseated.
4. Turn the tire and wheel over and unseat the
second bead as described in step 3.
5. Thoroughly lubricate rim flange and tire bead
with a thin solution of vegetable oil soap in
water or equivalent rubber lubricant recom-
mended for this requirement (never use
petroleum-base lubricants or silicones).
6. Force part of bead across rim from valve into
well. Starting at valve, pry bead over rim
flange using two 18" (457,2 mm) tire irons.
Continue by taking short bites to avoid dam-
age to bead until top bead is completely over
the rim flange.
7. Bring assembly to upright position and pull
tube out of tire casing. When only tube
requires repair or replacement, thoroughly
inspect inside of tire casing for foreign material
or damage and make sure both tube and
inside of casing are dry before reinserting
tube.
8. To completely remove tire from rim, turn
assembly over and lubricate second tire bead
and rim flange. Be sure one side of bead still
on the rim is in the rim well and insert tire irons
under opposite side of bead. Work rim slowly
out of tire by taking small bites alternatively
using both tire irons.
