MAINTENANCE
STANDARD TIGHTNING TORQUES
If nuts, bolts, or other parts are not tightened to the specified torque, it will cause them to loosen or damage to the tightened
parts, and this will cause failure of the machine or problems with operation. Always pay careful attention when tightening
parts. Unless otherwise specified, tighten the metric nuts and bolts to the torque shown in the table below. If it is necessary to
replace any nut or bolt, always use a Komatsu genuine part of the same size as the part that was replaced.
