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

Valve Lash Setting For 3114, 3116, and 3126
Valves Dimension of Gauge
Inlet 0.38 0.08 mm (0.015 0.003 inch)
Exhaust 0.64 0.08 mm (0.025 0.003 inch)

The rotation of the crankshaft is viewed from the flywheel end.
Rotation Counterclockwise
Check and Adjust with No. 1 Piston On this Stroke.(1) Top Center Compression Stroke(2)
Injectors 3-4
Inlet Valves 1-2
Exhaust Valves 1-3
Check and Adjust with No. 1 Piston On this Stroke. Top Center Exhaust Stroke
Injectors 1-2
Inlet Valves 3-4
Exhaust Valves 2-4
Firing Order 1-3-4-2
(1) Refer to Testing and Adjusting, "Finding Top Center Position for No. 1 Piston" for more information.
(2) Put No. 1 Piston at the top center position. After the top center position is found and the adjustments have been made for the correct cylinders, remove the top center bolt. Turn the flywheel in a counterclockwise direction by 360 degrees. This puts No. 1 Piston at the top center position on the other stroke. Install the top center bolt in the flywheel and complete the adjustments for the cylinders that remain.
