Put 6V-3075 Dial Indicator (1) that is installed in 6V-9058 Fixture Assembly (2) into position on the fuel injector. Make sure that the magnetic base of the timing fixture is on the top surface of the fuel injector's retainer and that the contact point is on the top surface of shoulder (6) .Note: The pointer on both dials on the dial indicator must indicate 0.00 0.20 mm (0.000 0.008 inch).
If the dial indicator pointers are within the range of 0.00 0.20 mm (0.000 0.008 inch), no adjustment is necessary. Proceed to Step 11.
If the dial indicator pointers are not within the range of 0.00 0.20 mm (0.000 0.008 inch), complete Steps 7 through 10.
Loosen the rocker arm adjustment screw locknut (9) on the fuel injector that requires adjustment.
Put 6V-3075 Dial Indicator (1) that is installed in 6V-9058 Fixture Assembly (2) into position on the fuel injector. Make sure that the magnetic base of the timing fixture is on the top surface of the fuel injector's retainer and that the contact point is on the top surface of shoulder (6) .
Turn rocker arm adjustment screw (8) until the dial indicator indicates "0".
Tighten rocker arm adjustment screw locknut (9) to a torque of 200 25 N m (150 18 lb ft), and check the adjustment again. If necessary, do this procedure until the adjustment is correct.
Remove the timing pin from the crankshaft when the fuel timing check is completed.
