TECHNICAL INFORMATION
HARDWARE
GENERAL
The Boomer 8N tractor has been built using metric
hardware.
NOTICE: Be sure to use the hardware specified
when using tapped holes, as trying to install a metric
bolt in an inch thread, or an inch bolt in a metric
thread, will damage the thread.
Certain hardware must be tightened to specific
torque specifications. If specific torque specifications
are not noted, tighten the hardware to the standard
torque chart specification listed in this manual.
PLATING
Hardware used on New Holland tractors is plated
with zinc chromate (gold color). Gold colored
hardware has different torquing requirements from
unplated or zinc plated (silver color) hardware
because of the difference in the coefficient of friction
of the plating material. The torque charts in this
manual list the correct specifications for gold, silver,
and unplated bolts.
NUT TIGHTENING
Whenever possible, the nut should be tightened, not
the head of the bolt. When tightening using the bolt
head, the clamp load can be lost because some of
the torque applied twists the bolt instead of
tensioning (stretching) it. The tension on the bolt is
what holds the joint together.
Approximately 90% of the torque applied during
assembly goes to overcoming friction between the
parts. The other 10% is used to tension (stretch) the
bolt. After assembly, the frictional forces disappear,
which is the basis for the saying “If it does not fail
during assembly, it will not fail in service.” The bolt
may later fail due to other factors, but not from being
over tightened.
LOCKNUTS
Most locknuts are coated with a special lubricant that
is dry to the touch. Anytime a locknut is used, a lower
than normal torque is required. Refer to the torque
charts in this manual for specific values.
JAM NUTS
When using a jam nut to lock a regular nut, the jam
nut should be installed first and tightened to one half
the recommended torque, then held in place while
installing a regular nut to the recommended torque.
THREAD LUBRICATION
The addition of anti-seize compound, Molykote, oil,
graphite, or any other lubricant to a bolt decreases
the friction between it and a nut. This makes it
necessary to reduce the recommended torque to
prevent over tensioning of the bolt. When using the
torque charts in this manual, decrease the value by
20% whenever a lubricant is used.

your tractor model.
2. Never negotiate sharp turns with the power
take-off under a heavy load; this may damage the
universal joints on the transmission shaft
connected to the power take-off.
3. Never stand between the reversing tractor and
the implement when hitching.
4. When using implements that require the tractor
to be stationary with the engine running, keep the
shuttle lever in the neutral position, apply the
hand brake and use suitable wheel chocks.
5. Do not operate machines connected to the power
take-off without first ensuring that the operating
range of the machine is free of bystanders.
Also check that all rotating parts connected to the
power take-off shaft are correctly protected.
