GENERAL INTRODUCTION
1–24
3.
With new flange (w/o grooves)
NOTICE
Some bolts/nuts are applied friction stabilizer on thread surface. Note that their tightening torques are different
from those of plated-only bolts/nuts even if the strength class is same. (Threads with Neotorquer are colored in
light red.)
HINT
The * below the hyphen of a part number shows a thread diameter and length under head, so the numbers vary
depending on type.
LIST OF TIGHTENING TORQUE
Apply a tightening torque specified in the strength class of the bolt/nut used.
NOTICE
Refer to the service manual because tightening torques of some parts do not conform to it due to their tightening
conditions, strength classes, and surface treatments.
