Blow out the shear pin hole with compressed
air, and put a drop of oil in the hole.
9.
Insert the new shear pin into the bore, as
shown in
Figure 157
. If the pin does not
freely slide into the bore, DO NOT hammer
on the pin or you will mushroom the shear
pin head, preventing installation. Instead,
file a slight chamfer on the end of the pin to
make it easier to align and insert.
7.
Use the magnet to remove the shear pin
head, then rotate the lathe spindle by hand
to line up the inner and outer bores, as
shown in
Figure 156
. Next, use the magnet
to remove the other half of the broken shear
pin when it becomes visible.
