GENERAL TIGHTENING TORQUE 
SPECIFICATIONS
This chart specifies tightening torques for stan-
dard fasteners with a standard ISO thread pitch. 
Tightening torque specifications for special com-
ponents or assemblies are provided for each 
chapter of this manual. To avoid warpage, tight-
en multi-fastener assemblies in a crisscross pat-
tern and progressive stages until the specified 
tightening torque is reached. Unless otherwise 
specified, tightening torque specifications re-
quire clean, dry threads. Components should be 
at room temperature.

NOTE:
Connecting rod nut
Tighten the connecting rod nuts to 15 Nm (1.5 m·kg, 11 ft·lb), and then tighten them further to reach the 
specified angle 175°–185°.
NOTE:
Crankcase bolt
1. First, tighten the bolts to approximately 20 Nm (2.0 m·kg, 14 ft·lb) with a torque wrench.
2. Loosen all bolts one by one following the tightening order and then retighten the bolts 25 Nm (2.5 
m·kg, 18 ft·lb) with a torque wrench.
3. Loosen all bolts one by one following the tightening order and then tighten them to 27 Nm (2.7 m·kg, 
20 ft·lb) again.
NOTE:
