PREVENTIVE MAINTENANCE
WHEEL NUT TORQUE
At the first scheduled lube interval, have all wheel nuts torqued to their
specified value. Thereafter, wheel nuts MUST be checked at least once
a week. Contact the service department at any authorised Kenworth
dealership for information on torque values applicable to the wheels installed
on your truck or see the table below.
The tightening sequence applies to all wheels except Gunite rims. Wheel
nuts must be tightened in three stages, in the sequence shown below, for
the particular wheel type, using a suitable calibrated torque wrench, making
sure not to rotate captive washers.
Tightening sequence must be strictly adhered to or misalignment may occur.
Never tighten nut fully while others are loose.
