TORQUE TABLES AND CONVERSION CHARTS
This manual provides dual dimensioning for many
specifications. Metric units are specified first, with
U.S. standard units in parentheses. When torque val-
ues are not specified in the assembly instructions
contained in this manual, use the standard torque
value for the hardware being used. Standard value
torque tables are contained in this chapter for metric
and SAE hardware.
NOTE: This truck is assembled with both metric and
SAE (U.S.) hardware. Reference the correct table
when determining the proper torque value.
References throughout the manual to standard
torques or other standard values will be to one of
the following tables. Do not use standard values
to replace specific torque values in assembly
instructions.
For values not shown in any of the charts or tables,
standard conversion factors for most commonly used
measurements are provided in the following tables.
