Put the push rod travel dial indicator in the center of the

injector push rod plunger. Lower the indicator to within

0.63 mm [0.025-inch] of fully compressed position, and

tighten the thumbscrew to hold the indicator in position.

Set the dial indicator at ‘‘0’’ (zero). Lock the indicator face

with the thumbscrew.

Rotate the crankshaft in the opposite direction of engine

rotation (counterclockwise ) through TDC to 45 degrees

before top dead center (BTDC).

NOTE: This step is necessary to remove the gear train lash

and to provide more accurate indicator readings.

Observe the dial indicator readings prior to crankshaft

rotation to assist in later determining BTDC piston setting

and timing reading.

NOTE: If the crankshaft is rotated beyond the -5.161 mm

[-0.2032-inch] position, the crankshaft must be rotated coun-

terclockwise back to 45 degrees BTDC. Repeat the follow-

ing step.

Rotate the crankshaft slowly in the direction of engine

rotation (clockwise ) until a reading of -5.161mm [-0.2032-

inch] BTDC is reached on the piston travel dial indicator.
