Onan RDJF User Manual

Assembly Torques and Special Tools
The assembly torques given here will assure proper
tightness without danger of stripping threads. If a
torque wrench is not available, estimate thedegree
of
tightness necessary 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 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.
