Typical example
1. Install Tooling (A). See illustration 72.
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 14.
Note: Any necessary adjustment must be made on
the flywheel housing. Then, recheck the concentricity.
Alignment 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 to the correct torque.
