60-2 Crank Trigger Wheel Diagram - Tooth Positions A/B/C, VR Sensor Alignment

This hand-annotated schematic shows a 60-2 (60-minus-2) crankshaft trigger wheel and how its teeth relate to ignition/timing trigger positions. The wheel diagram is labeled with tooth numbers around its circumference (0, 1, 2, up to 59), with a two-tooth gap implied by the '60-2 wheel' label. Key annotations state that 12° BTDC corresponds to tooth 54, the VR (variable reluctance) sensor aligns with tooth 56, and 60° back from the CKP reference is tooth 47, marked as 'trigger Position A'. From Position A, the diagram indicates '120° later' arriving at trigger position B (near tooth 6/14 area), and another '120° later trigger C tooth 26' for trigger position C. It also notes trigger return points: '8 teeth later trig return B' and '8 tooth later trig c return' (near tooth 34), showing the pulse width of each trigger event as 8 teeth. A reader can learn the angular relationships between the three trigger positions (A, B, C) spaced 120° apart on the 60-2 wheel, which teeth correspond to each event, and the sensor alignment reference—useful for setting up aftermarket engine management or understanding a distributorless ignition trigger scheme on this owner's 1993 Ford Probe project.
