4. Calculate the difference between the lowest
measurement and the highest measurement of the
four locations. This difference must not be greater
than 0.03 mm (0.001 inch) for every 25 mm
(1.0 inch) of the radius of the flywheel. The radius
of the flywheel is measured from the axis of the
crankshaft to the contact point of the dial indicator.

Typical example
1. Install Tooling (A) in illustration 114 , as shown.
2. Set the pointer of the dial indicator to 0 mm
(0 inch).
3. Turn the flywheel. Read the dial indicator for every
45 degrees.
4. Calculate the difference between the lowest
measurement and the highest measurement of the
four locations. This difference must not be greater
than 0.30 mm (0.012 inch).

Dial Gauge
Concentricity of the Flywheel
Housing
Note: This check must be made with the flywheel
and the starter removed and the bolts for the flywheel
housing tightened lightly.
Illustration 115
Typical example
1. Install Tooling (A). See illustration 115 .
2. Set the pointer of the dial indicator to 0 mm
(0 inch).
3. Check the concentricity at intervals of 45 degrees
around the flywheel housing.
4. Calculate the difference between the lowest
measurement and the highest measurement. This
difference must not be greater than the limit that is
given in Table 16 .
Note: Any necessary adjustment must be made on
the flywheel housing. Then, recheck the
concentricity.
