(10) Scribe a line on the damper (or crankshaft pulley) in line with the end of the pointer.
(11) Rotate the crankshaft opposite the direction of rotation slowly until the hand of the dial indicator just stops
(12) Rotate the crankshaft opposite the direction of rotation until the indicator hand just starts to move. Reset
dial to "0". Continue turning the crankshaft slowly until indicator reading is .010 inch--then stop turning.
(13) Scribe a second line on the vibration damper (or crankshaft pulley) in the same manner as in Step 10.
(14) Scribe a third line halfway between the first two lines. This is positive top-dead-center. The three scribed
lines are shown on the crankshaft pulley. Remove the indicator from the engine.
Make certain that the crankshaft pulley retaining bolt is not loosened
while turning the crankshaft. The bolt must be tightened to 290-310 lb-ft
torque if it becomes loose.
(15) Install the injector assembly. Swing the injector and valve rocker arms back into position and install the
rocker arm brackets and tighten the bolts to 90-100 lb-ft torque. Adjust the valve clearance and time the
injector. Rotate the crankshaft until the exhaust valves in the selected cylinder are open.
(16) Install the dial indicator again so the spindle of the indicator rests on top of the injector follower as
illustrated. Set the indicator dial to "O". Rotate the crankshaft slowly in the direction of rotation, and stop
when the TDC mark on the vibration damper or crankshaft pulley lines up with the pointer.
