WARNING: SHEAR BOLTS MAKE A
LOUD
NOISE
WHEN
SHEARED.
IMMEDIATELY SHUT THE TRACTOR
IGNITION OFF AND DETERMINE THE
CAUSE OF SHEARING.
Shear bolts will make a loud noise when they shear.
This is your warning to turn off the tractor ignition
immediately and determine the cause of the shear.
When replacing sheared bolts, always tighten them
securely using lock nuts. The shear bolts must be
the correct hardness to ensure safety (See Figure
61).
Warning: using a harder bolt in a shear bolt
location can cause damage to vital and more
expensive drive components.

LIGNMENT
Make sure the sprockets are in line with the shafts
(See Figure 62 and Figure 63). 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 64). This
faulty alignment will result on excessive wear on
both the chain and sprockets.

Clarity).
