TIRES & WHEELS
Tire Wear and Damage
Inspect tires periodically for wear or damage. Tires with worn
edges or distorted profiles require replacement. Tires with sig
-
nificant damage in the tread area or side wall, require immedi
-
ate evaluation before replacing machine into service.
Wheel and Tire Replacement
Replacement wheels must have the same diameter and pro
-
file as the original. Replacement tires must be the same size
and rating as the tire being replaced.
Use of genuine parts is recommended.
Both tires/wheel on the same axle must be replaced:
• If the overall diameter of the tire is less than 400 mm.
• If any uneven wear is discovered.
A tire with significant damage in the tread area or sidewall
requires immediate evaluation before placing the machine into
service. If a cut, tear, chunk, or other discrepancy exceeds any one
or more of the following dimensions, the tire must be replaced:
76 mm long, 19 mm wide, 19 mm deep
• If the metal wheel is visible at any point through the tread
area of the tire.
• If more than one discrepancy exists in any quadrant of the
wheel (within 90 degrees of one another).
Wheel Installation
It is extremely important to apply and maintain proper
mounting torque.
WHEEL LUG NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER
TORQUE TO PREVENT LOOSE WHEELS, BROKEN LUG NUTS, AND POSSIBLE
SEPARATION OF WHEEL FROM THE AXLE. BE SURE TO USE ONLY THE LUG
NUTS THAT 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 fas
-
teners. Over-tightening will result in breaking the lug nuts or
permanently deforming the mounting holes in the wheels.
The proper procedure for attaching wheels is as follow:
