Section 5. Wheel Assembly, Tires, and Axle
5-7 Model 6036/6036T S/N 9B0499 and Before
9. Remove the valve stem from the rim base.
10. Refer to paragraph 5.1.12 for tire mounting
instructions.
5.1.6 Wheel Cleaning
Remove all rust, corrosion, dirt, and other foreign
material from all metal surfaces. This is especially
important in the rim gutter and bead areas, and
mating surface of the lock ring.
Warning !
Assembling dirty or rusty rim components is
dangerous. Dirt and rust prevent components
from seating properly which could result in an
explosive separation. Such explosions could
result in severe injury or death to the operator
and to those in the area.
5.1.7 Wheel and Tire Inspection
and Replacement
1. Inspect the air-liquid valve core and stem, Fig.
5.2. Replace the entire valve if either compo-
nent is damaged. Replace the core O-ring
and stem seal regardless of condition.
2. Replace any tire that is worn or cut through
the cords. When replacing tires, follow the tire
manufacturers recommendations.
3. Check all metal surfaces for rust, corrosion,
cracks, bent flanges, sprung lock ring, and
deep tool marks on rings or gutter areas.
Replace all damaged, worn out, or cracked
parts.
4. Replace the rim base and/or lock ring if there
is any wearing away of the metal mating
surfaces and/or if they are deformed, broken
or cracked, or pitted from corrosion.
5. Replace the sealing ring regardless of condi-
tion.
5.1.8 Tire and Wheel Lubrication
1. Apply lubricant to the bead seat area, tire
bead, and rim mating surfaces prior to mount-
ing the tire.
2. Use only those lubricants recommended by
rim and tire manufacturers.
3. Lubricate the new sealing ring with an ap-
proved vegetable-based lubricant.
Warning !
Never inflate beyond 35 psi (2,4 bar) pressure.
If beads have not seated by the time pressure
reaches 35 psi
(2,4 bar), deflate the assembly,
reposition the tire on the rim, relubricate and
reinflate. After seating beads, adjust inflation
to recommended pressure. Allowing air
pressure to build within the assembly in an
attempt to seat the beads is a DANGEROUS
PRACTICE. In seating beads, inflation beyond
35 psi (2,4 bar) may break the bead (or even
the rim) with explosive force sufficient to cause
serious physical injury or death.
5.1.9 Mixing Hydrofill Solution
Prepare the hydrofill mixture by pouring calcium
chloride into water; never add water to calcium
chloride as considerable heat is generated in this
mixing process. Let the solution cool to atmos-
pheric temperature before pumping it into the tire.
To mix and cool the solution, place the pump
control in the FILL position and use the pump to
circulate the solution through the core ejector body
and back into the reservoir.
5.1.10 Filling a Tire or a Tube
within a Tire with Hydrofill
1. Be sure you’ve read and understood the
warning notices and general instructions in
paragraph 5.1.
2. Place the wheel assembly with the valve stem
straight up in a safety cage, Fig. 5.1. Attach
clip on chuck, insert the valve core in the
stem, Fig. 5.2, then withdraw handle of core
ejector tool. Stand to the side during inflation.
3. Pressurize the tire to approximately 3 psi (0,21
bar). Check for proper alignment of all compo-
nents.
• If assembly is incorrect, STOP, DEFLATE,
correct the assembly and repeat the
procedure.
• If assembly is okay, continue to inflate to
35 psi (2,4 bar).
4. To fill a tire 75 percent with water solution, first
inflate tire to 35 psi
(2,4 bar) after the beads
have been fully seated in the mounting
procedure. Jack up the wheel, if done on a
forklift, and turn the wheel to bring valve to top
position.
