Hello and welcome to just answer.i can help you with this..Read the proceedure all the way and if you have any questions let me know..

 

  • Select any cylinder for the timing check.
  • Remove the rocker arm assembly for the cylinder selected. Refer to "1.3.2 Removal of Rocker Arm Assembly" .
  • Remove the injector for that cylinder. Refer to "2.3.2 Removal of N2 Electronic Unit Injector" .
  • Carefully slide a rod, approximately 304.8 mm (12 in.) long, through the injector tube hole until the end of the rod rests on top of the piston.
  • Using the 3/4 in. square drive hole in the center of the crankshaft pulley and a 3/4 in. drive breaker bar, turn the crankshaft slowly in the direction of engine rotation. See Figure "Barring Engine Over" . Stop when the rod reaches the end of its upward travel.

    Figure 26. Barring Engine Over

    Note: The cylinder selected must be on the compression stroke when performing this check.

  • Remove the rod and turn the crankshaft, opposite the direction of rotation, between 1/16 and 1/8 of a turn.
  • Select a dial indicator with 0.0254 mm (0.001 in.) graduations and a spindle movement of at least 25.4 mm (1 in.). Provide an extension for the indicator spindle. The extension must be long enough to contact the piston just before it reaches the end of its upward stroke.
  • Install a magnetic dial indicator base in a suitable place on the cylinder head and position the dial indicator over the injector hole tube.
  • Attach a suitable pointer to the gear case cover. The outer end of the pointer should extend over the vibration damper.
  • Turn the crankshaft slowly in the direction of engine rotation until the indicator hand just stops moving. Continue turning the crankshaft until the indicator hand starts to move again.
  • Reset the dial to zero.
  • Turn the crankshaft until the indicator reading is 0.254 mm (0.010 in.).
  • Scribe a line on the vibration damper in line with the end of the pointer.
  • Slowly turn the crankshaft opposite the direction of engine rotation until the indicator hand just stops moving. Continue turning the crankshaft until the indicator hand starts to move again.
  • Reset the dial to zero. Then turn the crankshaft in the same direction until the indicator reading is 0.254 mm (0.010 in.).
  • Scribe a second line on the vibration damper in line with the end of the pointer.
  • Scribe a third line half way between the first two lines. This is top dead center for the cylinder selected when the pointer is lined up with it.
  • Remove the dial indicator and base from the engine.
  • Install the injector that was removed. Refer to "2.3.5 Installation of the N2 Electronic Unit Injector" .
  • Install the rocker arm assemblies. Refer to "1.3.3 Installation of Rocker Arm Shaft Assembly" .
  • Turn the crankshaft opposite the direction of engine rotation while watching the injector rocker arm cam follower for the cylinder selected. Turn the crankshaft until the cam follower is on the base circle of the injector lobe of the cam.
  • Install a magnetic dial indicator base on the cylinder head. Install a dial indicator so that the spindle rests directly on the injector cam follower roller for the cylinder selected.

    Note: The spindle should be on the center line of the injector cam follower roller pin in order to get an accurate measurement of cam lift.

  • Turn the crankshaft slowly, in the direction of engine rotation, until the center mark on the vibration damper lines up with the pointer.
  • Check the dial indicator reading and compare the reading with the values listed in Table "Camshaft Timing Setting Dimensions" to determine the correct indicator reading.
