Maintenance Section 5-5

Proper Torque For Fasteners

The chart lists the correct tightening torque for fasteners. When bolts are to be tightened or replaced, refer to

this chart to determine the grade of bolts and the proper torque except when specific torque values are

assigned in manual text.
Recommended Torque in Foot Pounds Unless Otherwise Stated in the Manual*

NOTE:

These values apply to fasteners as received from supplier, dry or when lubricated with normal engine

oil. They do not apply if special graphited or molydisulphide greases or other extreme pressure lubricants are

used. This applies to both UNF fine and UNC coarse threads
