Section 5 Wheel Assembly, Tires, and Axle

5-7

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.

Warning

Never inflate beyond 35 psi (241,1 kPa)

pressure. If beads have not seated by the time

pressure reaches 35 psi

(241,1 kPa), 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 assem-

bly in an attempt to seat the beads is a

DANGEROUS PRACTICE. In seating beads,

inflation beyond 35 psi (241,1 kPa) 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

(20,7 kPa). Check for proper alignment of all

components.

• If assembly is incorrect, STOP, DEFLATE,

correct the assembly and repeat the

procedure.

• If assembly is okay, continue to inflate to

35 psi (241,1 kPa).

4. To fill a tire 75 percent with water solution, first

inflate tire to 35 psi

(241,1 kPa) 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.

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

component 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. (Three Piece Rim S/N OF1191 & Before)

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. (Three Piece Rim S/N OF1191 & Before)

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. (Three Piece Rim S/N OF1191 & Before)

Lubricate the new sealing ring with an ap-

proved vegetable-based lubricant.
