18. Insert the valve core in the stem and pressur-
ize the tire as follows:
AIR PRESSURES:
13.00 x 24 Size, 10 ply (Standard)
55 psi (3,79 bar)
15.00 x 19.5 Size, 12 ply (Optional)
60 psi (4,14 bar)
HYDROFILL MIXTURE:
13.00 x 24, 10 ply (Standard)
164 lb (74 kg) Calcium Chloride
to 33 gal. (125 liter) of water (each tire)
15.00 x 19.5, 12 ply (Optional)
120 lb (54 kg) Calcium Chloride
to 24 gal. (91 liter) of water (each tire)
5.1.11 Mounting Tire
1. Be sure you’ve read and understood the
warning notices and general instructions in
paragraph 5.1.
2. Refer to paragraph 5.1.12 or 5.1.13 when
mounting tire on wheel which is not attached
to forklift.
5.1.12 Mounting Standard Tire
on Three Piece Wheel
1. Be sure you’ve read and understood the
warning notices and general instructions in
paragraph 5.1.
2. Install the valve stem, Fig. 5.2, into the hole in
the rim and tighten to 45 to 55 lb-inch (5 to 6,2
N m). Make sure parts are clean, repainted if
necessary, and have been inspected for
damage and cracks before proceeding with
mounting.
3. Make sure correct parts are being assembled.
Lay rim base on block with the flange side
down. Place tire over rim base.
NOTE: A mechanical bead unseating and seating
tool may be purchased from the Iowa Mold Tooling
Company to facilitate step 4.
4. Place side flange over rim base and push
straight down with hands as far as possible.
Make sure flange does not bind on rim base.
5. Stand on side flange to position it below both
grooves in rim base and snap lock ring into
lock ring (Upper) groove. Be certain the
embossed “safety bulge” on the lock ring is up
toward the operator.
5. Inspect both sides of the tire to be sure beads
are evenly seated. If not, completely deflate
tire, unseat beads and repeat entire mounting
procedure.
6. Lower jack until tire is slightly deflected. With
pump not running and the pump control
handle at CHECK position, connect ejector
and remove core housing as described in
paragraph 5.1.1.
7. After connection is made, bleed pressure
down to about 5 psi (0,35 bar) by moving
pump control to EVACUATE. This is sufficient
pressure to keep the beads seated on the rim.
8. When this point is reached, start pump and
move pump control to the FILL position and
start hydroinflating the tire.
9. Check pressure in tire periodically with pump
gauge by placing pump in NEUTRAL or
CHECK position.
10. If pressure exceeds 20 psi (1,4 bar), move
pump control to EVACUATE until pressure is
bled back to not less than 5 psi (0,35 bar).
11. After pressure is lowered, continue pumping.
Repeat above steps as often as may be
necessary until water or solution weight added
to the assembly is equal to that shown in the
table.
12. Replace core housing in valve stem by
pushing handle (4) in until contact is made;
turn handle clockwise until core housing is
screwed tight in valve stem.
13. Withdraw handle, set pump to EVACUATE,
and pump all liquid from hose.
14. Shut off pump.
15. Unscrew ejector body (2) from valve.
16. To assure fully-seated beads inflate tire to 35
psi (2,4 bar) using a standard air line, and then
with valve stem at top, bleed pressure–and
excess water or solution–down to 1 to 2 psi
(0,07 to 0,14 bar)
above recommended
inflation.
17. Set final working pressure after tire has been
mounted on forklift and with weight of forklift
on tire. Position the wheel so valve stem is at
the bottom position. Use an air-water gauge
to check inflation pressure of each tire at least
once a week.
