6V-4186
or
6V-6019     Pin (Fuel Pump Timing)     1    For engines that are equipped with electronic governors, use the 4C-8180 Engine Timing Tool Group to check or adjust the engine timing. Refer to Tool Operating Manual, NEHS0638, "Using the 4C-8180 Timing Tool Group To Set Fuel Injection Pump Timing" for information that relates to the correct use of the engine timing tool.For engines with mechanical governors, use the following procedure to check or adjust the engine timing.
Position the No. 1 piston at the top center position on the compression stroke. Refer to Testing and Adjusting, "Finding The Top Center Position For No. 1 Piston".Note: Remove the plug from the fuel injection pump housing.
Illustration 1 g00361935
Removing the timing pin plug (typical example) (1) Timing pin plug
Remove plug (1) at the front end of the fuel injection pump housing.
Install 6V-6019 Fuel Pump Timing Pin (end with taper) through the hole in the injection pump housing.
If the timing is correct, the timing pin will go into the notch in the camshaft and the timing bolt will turn into the threaded hole in the flywheel. If the timing is NOT correct, the timing must be changed.Note: If the timing is correct, be sure that you remove the timing pin and the timing bolt before you proceed.If the timing was not correct, remove the timing pin. Use the procedure that follows to change the timing.

Ensure that the timing pin is removed before the bolts are loosened. Loosen the four bolts (3) that hold the automatic timing advance unit (4) onto the fuel pump camshaft.
Tighten the bolts (3) with fingers until there is a small amount of friction (slight drag) between the retainer and the automatic timing advance unit (4) . This friction will hold the unit against the timing gears. This prevents play (backlash) when gears are turned to the correct position.
Remove the timing bolt. Turn the flywheel until the timing pin will go into the groove in the injection pump's camshaft.
After installing the timing pin, turn the flywheel in the clockwise direction for a minimum of 30 degrees. This is the opposite direction of the engine rotation. When the No. 1 piston is at the top center position, this procedure will remove the play from the gears.
Then, turn the flywheel in the direction of normal engine rotation until the timing bolt engages with the threaded hole.
Tighten the bolts (3) to 25 N m (20 lb ft). Then, remove the timing pin from the injection pump housing.
Tighten the bolts (3) to 136 7 N m (100 5 lb ft). Then, remove the timing bolt from the flywheel.
Rotate the crankshaft counterclockwise for two revolutions. Check the timing again. If the timing bolt can be installed in the flywheel and the timing pin can be installed in the camshaft, the timing is correct.
If the timing is not correct, repeat Step 4.b through Step 4.h.Note: If the timing is correct, be sure that you remove the timing pin and the timing bolt before you proceed.Measuring the Fuel Injection Pump Timing Dimension
