FIGURE 29. CRANKSHAFT THROW ARRANGEMENTS.
The throws are not all aligned with each other, but extend from the centerline of the crankshaft at different
points. Their positions are arranged so the power strokes of the pistons occur regularly to provide a smooth
flow of power. There are a number of different throw arrangements that can be used, but generally the ones
pictured here are used.
