1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (viewed from the drive side).
Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m)
2. Move the actuator in the clockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it.
Tightening torque: 7^9 N.m (0.7^0.9 kgf.m)
3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

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).

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.

(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.
