Tip: For easy shear pin replacement in the
future, use the center punch or a scribe and
mark the end of the drive hub and the side of
the leadscrew with a timing mark to indicate
where true hole alignment is located. Next,
scribe a line on the leadscrew just where it
enters the drive hub, this line will indicate cor-
rect depth of leadscrew. Should the pin ever
shear again, line-up the marks, and drive out
the pin pieces, and tap in the new pin.
