SECTION 3. CHASSIS & TURNTABLE
3.1 TIRES & WHEELS
Tire Inflation
The air pressure for pneumatic tires must be equal to
the air pressure that is stenciled on the side of the JLG
product or rim decal for safe and proper operational
characteristics.
Tire Damage
For pneumatic tires, JLG Industries, Inc. recommends that
when any cut, rip, or tear is discovered that exposes side-
wall or tread area cords in the tire, measures must be
taken to remove the JLG product from service immedi-
ately. Arrangements must be made for replacement of the
tire or tire assembly.
For polyurethane foam filled tires, JLG Industries, Inc. rec-
ommends that when any of the following are discovered,
measures must be taken to remove the JLG product from
service immediately and arrangements must be made for
replacement of the tire or tire assembly.
• a smooth, even cut through the cord plies which
exceeds 3 inches (7.5 cm) in total length
• any tears or rips (ragged edges) in the cord plies which
exceeds 1 inch (2.5 cm) in any direction
• any punctures which exceed 1 inch in diameter
• any damage to the bead area cords of the tire
If a tire is damaged but is within the above noted criteria,
the tire must be inspected on a daily basis to insure the
damage has not propagated beyond the allowable crite-
ria.
Tire Replacement
JLG recommends a replacement tire be the same size, ply
and brand as originally installed on the machine. Please
refer to the JLG Parts Manual for the part number of the
approved tires for a particular machine model. If not using
a JLG approved replacement tire, we recommend that
replacement tires have the following characteristics:
• Equal or greater ply/load rating and size of original
• Tire tread contact width equal or greater than original
• Wheel diameter, width, and offset dimensions equal to
the original
• Approved for the application by the tire manufacturer
(including inflation pressure and maximum tire load)
Unless specifically approved by JLG Industries Inc. do
not replace a foam filled or ballast filled tire assembly
with a pneumatic tire. When selecting and installing a
replacement tire, ensure that all tires are inflated to the
pressure recommended by JLG. Due to size varia-
tions between tire brands, both tires on the same axle
should be the same.
Wheel Replacement
The rims installed on each product model have been
designed for stability requirements which consist of track
width, tire pressure, and load capacity. Size changes such
as rim width, center piece location, larger or smaller diam-
eter, etc., without written factory recommendations, may
result in an unsafe condition regarding stability.
Wheel Installation
It is extremely important to apply and maintain proper
wheel mounting torque.
WHEEL NUTS MUST BE INSTALLED AND MAINTAINED AT THE
PROPER TORQUE TO PREVENT LOOSE WHEELS, BROKEN STUDS,
AND POSSIBLE DANGEROUS SEPARATION OF WHEEL FROM THE
AXLE. BE SURE TO USE ONLY THE NUTS MATCHED TO THE CONE
ANGLE OF THE WHEEL.
Tighten the lug nuts to the proper torque to prevent
wheels from coming loose. Use a torque wrench to tighten
the fasteners. If you do not have a torque wrench, tighten
the fasteners with a lug wrench, then immediately have a
service garage or dealer tighten the lug nuts to the proper
torque. Over-tightening will result in breaking the studs or
permanently deforming the mounting stud holes in the
wheels. The proper procedure for attaching wheels is as
follows:
1.
Start all nuts by hand to prevent cross threading. DO
NOT use a lubricant on threads or nuts.
2.
Tighten nuts in the following sequence:
