Komatsu — TORQUE TABLES AND CONVERSION CHARTS

OM1200 02/11 Torque Tables And Conversion Charts - Section 12 Page 12-1 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. 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. NOTE:

This truck is assembled with both metric and SAE (U.S.) hardware. Reference the correct table when determining the proper torque value. 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.
