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:
3. The tightening of the nuts should be done in stages. Using
the recommended sequence, tighten the nuts per wheel
torque chart following.
4. Wheel nuts should be torqued after the first 50 hours of
operation and after each wheel removal. Check torque every
3 months or 150 hours of operation.
