Tightening Torque List
Tightening Torques For Main Fasteners
"Wet" means that the threads of the relevant item should be coated with engine oil before tightening.The items whose torque specifications are marked with asterisks (*) must be tightened using special tools in order that the torque may be controlled precisely.Tightening Torques for Standard Bolts and Nuts
a. The table above applies only to standardized bolts and nuts.b. All torques shown assume use of spring washer together with bolts and nuts.c. All bolts and nuts appearing in this manual should be tightened according to this table unless otherwise indicated.d. Standard bolts and nuts should be tightened in "dry" condition, without lubricating their threads with oil.Tightening Torques for Standard Eye Bolts (for Dry Condition)
