Assembly Torques
The torque values given in Table 1 have been deter-
mined for the specific applications. Standard torque
values must not be used where those listed in Table
1
apply. The engine assembly torques given here will
assure proper tightness without danger
of stripping
threads.
All threads must be clean and lubricated with
new engine
oil before torquing.
Check all studs, nuts, and capscrews, and tighten as
required to keep them from working loose. Refer to
the PARTS MANUAL for the location of washers and
capscrews.
