When using the torque data in the charts above, the following rules should be observed.
1. Bolt manufacturer’s particular specifications should be consulted when provided.
2. Flat washers of equal strength must be used.
3. All torque measurements are given in kilogram-meters.
4. Torque values specified are for bolts with residual oils or no special lubricants applied.
If special lubricants of high stress ability, such as Never-Seez compound graphite and oil, molybdenum
disulphite, collodial copper or white lead are applied, multiply the torque values in the charts by the
factor .90. The use of Loctite does not affect the torque values listed above.
5. Consult the parts manual for torque values on socket head capscrews.
WARNING
Anytime a gear-bearing bolt is removed, it must be replaced with a new bolt of the identical grade and size. Once a bolt
has been torqued to 75% of its proof load and then removed, the torque coefficient may no longer be the same as when
the bolt was new thus giving indeterminate clamp loads after torquing. Failure to replace gear-bearing bolts may result in
bolt failure due to metal fatigue causing serious injury or DEATH.
