GENERAL INFORMATION
GENERAL INFORMATION
This manual provides dual dimensioning for many
specifications. Metric units are specified first, with
U.S. standard units in parentheses. When torque
values 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.
This truck is assembled with both metric and SAE
(U.S.) hardware. Reference the correct table when
determining the proper torque value.

References
throughout
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.
Effect Of Special Lubricants
The Komatsu engineering department does not
recommend the use of special friction-reducing
lubricants, such as Copper Coat, Never-Seez®, and
other similar products, on the threads of standard
fasteners where standard torque values are applied.
The use of special friction-reducing lubricants will
significantly alter the clamping force being applied to
fasteners during the tightening process.
2-2
If special friction-reducing lubricants are used with
the standard torque values listed in this chapter,
E.2-0000051234
excessive stress and possible breakage of the
fasteners may result.
Where the torque tables specify "Lubricated Threads"
for the standard torque values listed, these standard
torque values are to be used with simple lithium
base chassis grease (multi-purpose EP NLGI) or a
rust-preventive grease (see below) on the threads
and seats unless specified otherwise.
NOTE: Ensure the threads of fasteners and tapped
holes are free of burrs and other imperfections before
assembling.
