9.2. BOLT TORQUE VALUES
The tables shown below give correct torque values for various bolts and
capscrews. Tighten all bolts to the torque specified in the chart unless otherwise
noted. Check tightness of bolts periodically, using bolt torque chart as your guide.
Replace hardware with the same strength bolt.
Figure 9.1 Pattern for Tightening Wheel Bolts
Torque figures indicated above are valid for non-greased or non-oiled threads
and head unless otherwise specified. Therefore, do not grease or oil bolts or
capscrews unless otherwise specified in this manual. When using locking
elements, increase torque values by 5%.
