Zusammenfassung:A crankshaft casting pattern insert 10 which includes selectively adjustable portions 14, 16, which respectively correspond the front and rear main bearing journal portions of the crankshaft. Each adjustable portion 14, 16 includes a removable insert or member 18, a key member 20, several "vertical" spacers 22, several "lateral" spacers 24, and a fastener 26. Adjustable portions 14, 16 allow the pattern 10 to be selectively modified in shape, effective to compensate for pattern wear and to allow multiple crankshafts to be produced which have a substantially similar balance capability. Pattern 10 may also include several validation pads or points 50 which allow the produced crankshafts to be measured with improved accuracy.
