Note: Ensure that the engine is in time. Refer to Testing And Adjusting, "Camshaft Timing".Note: Refer to Testing and Adjusting, "Crankshaft Position for Fuel Injector Adjustment and Valve Lash Setting". All of the injectors can be checked or adjusted with the crankshaft positions that are given in the chart. This check will make sure that the pushrod lifters are off the lobes and on the base circles of the camshafts. Refer to the TMI (Technical Marketing Information) for the correct fuel timing dimension to use.

1U-8869 Dial Indicator
The digital dial indicator needs to be programmed to read actual timing dimensions. Since the 9U-5138 Setting Gauge in the timing and fuel setting tool group is 87.00 mm, set the digital dial indicator for 87.00 mm. Use the following steps in order to program the indicator to read 87.00 mm.
Turn the indicator to the ON position by pushing the "on/off" button.
Push the "in/mm" button so the display shows "mm".
A negative "-" sign should be in the display window under "REV". If that space is blank, push the "+/−" button so the display shows a negative "-" sign. When this is done, the movement of the plunger into the indicator will be displayed. The display will be shown as a negative movement. The movement of the plunger out of the indicator will be displayed as a positive movement.
Push the preset button and hold the preset button down until there is a flashing "P" in the upper right corner of the display. Then release the button.
Push the preset button and hold the preset button down until the flashing "P" disappears and a flashing indicator bar is seen in the lower left corner of the display. Then release the button. Use the preset button so that this position is blank.
Push the preset button and hold the preset button down until the flashing indicator begins flashing under the first number position. The first number position is located in the fourth position to the left of the decimal. Then release the button. Momentarily pushing the preset will cause the display number in that position to change. Use the preset until this position reads zero (0).
Use the preset button to move the flashing indicator and change the display numbers until the display shows 0087.00 mm. Push the preset button and hold the preset button until the flashing "P" is shown in the upper right corner of the display. Release the preset button. Momentarily push the preset button so the flashing "P" and the zeroes to the left of 87.00 mm disappear.
The indicator can now be turned off. The indicator will retain the preset number in memory. To recall the preset number, repeat Steps 1.a through 1.d.
Install a 5P-4160 Indicator Contact Point in the indicator stem.
Install the indicator into the 9U-5233 Magnetic Fixture Group. Leave the collet loose.

(3) 9U-5138 Setting Gauge
Place the fixture and the indicator on the 9U-5138 Setting Gauge with the extension rod of the bracket on the step of the gauge. Position the indicator in the bracket so that the indicator plunger can travel adequately. Tighten the collet.
Repeat Steps 1.a through 1.d.

Momentarily push the preset button on the digital dial indicator in order to stop the "P" in the upper right hand corner from flashing. The display should show 87.00 mm. Place the 1U-8869 Dial Indicator and the 9U-5233 Magnetic Fixture Group in the correct position on the injector. Make sure that the magnetic base of the timing fixture is on the top surface of injector follower (4) and that the extension rod is on the top surface of shoulder on fuel injector body (5). Note: In order to ensure an accurate fuel timing dimension, the top surfaces of injector follower (4) and shoulder on fuel injector body (5) must be clean and dry.
The digital dial indicator should now read the actual fuel timing dimension of the injector that is being checked.
No adjustment is necessary if the dial indicator reads the correct fuel timing dimension. Refer to the TMI (Technical Marketing Information) for the engine that is being checked. Proceed to Step 12.
If the dial indicator does not read the correct fuel timing dimension or the desired fuel timing dimension, proceed with Steps 10 through 13.
Ensure that the 1U-8869 Dial Indicator and the 9U-5233 Magnetic Fixture Group are in the correct position on the injector. Loosen the locknut for the pushrod adjustment screw.
Turn the adjustment screw until the desired fuel timing dimension is read on the digital dial indicator. Note: Turning the adjustment screw clockwise will lower the fuel timing dimension. Turning the adjustment screw counterclockwise will increase the fuel timing dimension.Tighten the adjustment screw locknut to a torque of 70 15 N m (50 11 lb ft) and check adjustment again. If necessary, repeat the procedure until the adjustment is correct.
Remove the timing bolt from the flywheel when the fuel timing check is completed.
Turn the flywheel by 360 degrees in the direction of normal engine rotation. Install the timing bolt for the flywheel. Repeat the procedure for the other half of the engine.
