2 , the eccentric must be located at E , one - fourth of the wheel's circle , or 90
degrees , ahead of the crank - pin - assuming the engine to be running forward —
to the right . But before going further it is best to explain how to take the

... to accomplish this , the position of the eccentric must be changed to a point on
the wheel exactly its opposite in location - 90 degrees on the other side of the
main - pin — a quarterturn ahead of the crank with the wheel turning backward .
