Introduction
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.If the crankshaft, gear case and/or crank gear are replaced, it is necessary to calibrate the injection timing. The following steps show how to calculate/determine the new injection timing by measuring angular deviation between the crankshaft TDC and Crank Position sensor detected TDC.Note: Once complete the engine ecm must be reprogrammed with the new injection timing value.Follow all steps.Procedure
Illustration 1 g06220548
(1) TC Mark (Flywheel Housing)
(2) TC Mark (Flywheel)
Remove valve cover, and injector and rocker arm. Bring the piston of cylinder 4 to TDC.
Illustration 2 g06220554
(3) Dial Gauge
(4) Valve
(5) O-ring
Remove the #4 exhaust valve bridge arm and valve spring. Insert a small O-ring (5) so the valve does not fall into the cylinder.
Set dial gauge (3) on the tip of the valve (4).

(8) Flywheel
(9) Reference Line
Turn the flywheel counterclockwise and measure the position where the tip of the valve is the highest.
Stop the flywheel at the position where the tip of the valve is the highest. Put a tri - square (6) on the flywheel housing (7) and the flywheel (8) and draw a reference line (9).Do not drop the valve (4) into the cylinder. When measuring the highest position of the tip of the valve, do not rotate the flywheel clockwise. If you go past the highest point of the valve, back up the flywheel slightly and measure the highest point of the valve. The reference line (9) indicates the TDC of the crankshaft.

(14) Crankshaft Position Sensor
Connect a connector of the rotation sensor signal interface unit (10) to the crankshaft position sensor (14). Connect each clip of the rotation sensor signal interface unit (10) to the same test lead color of the tester (11). Switch on the rotation sensor signal interface unit (10).

(15) Pulsar Gear
(16) 14th Tooth
(17) Missing Teeth
Turn the flywheel and make sure that the voltage of the crankshaft position sensor goes from 0→ 5 V or 5 → 0 V.
Rotate the flywheel and align the crankshaft position sensor to the part of the pulsar gear (15) that is missing teeth (17). The 14th tooth (16) from the missing teeth is standard.
Slowly turn flywheel counterclockwise and stop flywheel at the point where needle of the tester changes momentarily from 0 → 5 V, the 14th tooth.That point is where the crankshaft position sensor detects TDC.

(20) Interval
Set the tri - square (6) on the reference line (9) on the flywheel housing side and mark the detection point of crankshaft position sensor TDC (19) on the flywheel.
Measure the interval (20) between the crankshaft TDC (18)
