Onan DJA Series User Manual

ASSEMBLY TORQUES
The assembly torques given here will assure proper tightness
without danger of stripping threads. If a torque wrench is
not available, estimate the degree of tightness necessaiy
for the stud, nut, or screw. Be careful not to strip threads.
Use reasonable force only and a wrench of normal length.
Specially designed Place Bolts (Fig. 14-1) do not require a
lockwasher or gasket. Do not attempt to use a lockwasher
with these bolts, it will defeat their purpose. Check all
studs, nuts and screws often and tighten as needed to keep
them from working loose.
