Front gear group ( 3116 and 3126 Engines) (1) Camshaft gear (2) Timing marks (3) Camshaft idler gear (4) Crankshaft gear (5) Idler gear (6) Oil pump gear The basis for the correct fuel injection timing and the valve mechanism operation is determined by the alignment of the timing for the front gear group. Align timing marks (2) on camshaft idler gear (3) with the holes on camshaft gear (1) and crankshaft gear (4). This alignment is required in order to provide the correct relationship between the piston movement and the valve movement.Crankshaft Positions for Valve Lash Setting
