Table 11 - Replacement Shear Bolts
If these designed shear points are not the problem
than most likely a sheared keyway in an individual
components is the problem. Clear the obstruction
that caused the overloading and repair/replace
components as necessary.
When replacing sheared bolts, always tighten them
securely using lock nuts. The shear bolts must be
the correct harness to ensure safety. (See Figure
180)

LIGNMENT
Make sure the sprockets are in line with each other.
(See Figure 181) If the sprockets are not aligned a
sideways pull will develop and will concentrate the
load on sides of the sprocket teeth and on the side
of the chain. (See
Figure 182
) This faulty
alignment will result on excessive wear on both the
chain and sprockets.
