N OT E
Check must be made with flywheel removed (refer to WP 0100). Install bolts for flywheel
housing and tighten lightly.
1. Install magnetic base (Figure 24, Item 1) and dial indicator (Figure 24, Item 3) on crankshaft (Figure 24,

4. Note reading on dial indicator every 45 degrees.
a. Calculate difference between lowest measurement and highest measurement.
b. Difference must not be greater than limit given in Table 2. If readings are greater than limits in Table 2,
