TESTING AND ADJUSTING
1. Fasten a dial indicator to the crankshaft flange
so the anvil of the indicator will touch the face of
the flywheel housing.
Bore Runout (radial eccentricity)
of the Flywheel Housing
2. Put a force on the crankshaft toward the rear
before reading the indicator at each point.
3. With dial indicator set at 0.0 mm (.000 in.) at
location (A), turn the crankshaft and read the
indicator at locations(B), (C) and (D).
4. The difference between lower and higher mea-
surements taken at all four points must not be
more than 0.30 mm (.012 in.), which is the maxi-
mum permissible face run out (axial eccentri-
city) of the flywheel housing.
1. With the dial indicator in position at (C), adjust
the dial indicator to 0 (zero). Push the crank-
shaft up against the top bearing. Write the mea-
surement for bearing clearance on line 1 in col-
NOTE: Write the dial indicator measurements
with their positive (+) and negative (-) nota-
tion (signs). This notation is necessary for
making the calculations in the chart correctly.
2. Divide the measurement from Step 1 by 2. Write
this number on line 1 in columns (B) & (D).
