15.3 BOLT TORQUE
CHECKING BOLT TORQUE
The table(s) shown below give correct torque values for various bolts and cap-screws. Tighten all bolts to
the torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt
torque chart as a guide. Replace hardware with the same strength bolt.
NOTE: Tighten the plastic insert (nylon lock) or crimped steel-type lock nuts to approximately 50% of the
dry torque shown in the chart, applied to the nut, not to the bolt head. Tighten the toothed or serrated-
type lock nuts to the full torque value.

Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise
specified. Therefore, do not grease or oil bolts or cap-screws unless otherwise specified in this manual.
When using locking elements, increase torque values by 5%. Reduce value by 10% if threads are oiled
before assembly.
* Torque value for bolts and cap-screws are identified by their head markings.
**Always install new or unused locking nuts whenever possible or practical to ensure the full locking
benefit.
This manual must stay with the machine/operator at all times.
