Wheel and Tire Replacement

JLG recommends that any replacement tire be the same size and brand
as originally installed on the machine or offered by JLG as an approved
replacement. Please refer to the JLG Parts Manual for the part number
of the approved tires for a particular machine model.
If any of the following is discovered during tire inspection, measures
must be taken to remove the JLG product from service immediately.
Arrangements must be made for replacement of the tire(s) or tire
assembly(s). Both tires/wheels on the same axle must be replaced:
• If the overall diameter of the tire is less than one of the following:
406 x 127 Tire – 15.55 in. (395mm) minimum
• 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:
3.0 in. (76 mm) long
0.75 in. (19 mm) wide
0.75 in. (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 wheel mount-
ing torque.
WHEEL SLOTTED NUTS MUST BE INSTALLED AND MAINTAINED AT THE PROPER TORQUE
TO PREVENT LOOSE WHEELS, A BROKEN NUT, AND POSSIBLE SEPARATION OF WHEEL
FROM THE AXLE.
Tighten the slotted nuts to the proper torque to prevent wheels from
coming loose. Use a torque wrench to tighten the slotted nuts. The
proper procedure for attaching wheels is as follows:
1. If not already installed, install shaft key (5) to shaft and align
with wheel keyway, install wheel and hub (3) onto tapered
shaft (4).
2. Start slotted nut (1) by hand to prevent cross threading. DO
NOT use a lubricant on threads or nut.
3.
Torque the slotted nut to 150 ft. lb. (203 Nm).
4. Install cotter pin (2), if hole in slots do not align with cotter
pin hole on the tapered shaft, continue to turn nut clockwise
to align nut with hole. Do not loosen to align hole.
