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,
