Shear Bolt
Refer to Figure 55
Your Great Plains sprayer is equipped with four shear
bolts
, two each side, to help prevent damage to the
booms. These are located at the inner boom pivot posts
at the ends of the center section. When the boom
encounters an obstruction, both bolts on that side fail,
allowing the boom to swing back.
If a pair of shear bolts breaks, replace them with a pair of
5 
8
-11 x 3-inch Grade 5 bolts (Great Plains part
802-160C). If this size and grade bolt is not immediately
available, you may temporarily substitute metric M14x2
Class 8.8 bolts.
Using a lower grade/class bolt causes nuisance shears.
Using a higher grade/class bolt may result in serious
equipment damage.
Inspect these bolts at the start of the spraying season to
insure the bolts have not been weakened through use or
rusting.
Stock a spare nut for each spare shear bolt, as the nut
end of the sheared bolt commonly falls away and is
difficult to locate.
