NOTE: Use the corresponding chart for the SAE 1, 2 or 3
flywheel housings being measured.
Using the illustration, mark the total horizontal value on
the horizontal side of the chart and the total vertical on the
vertical side of the chart.
Using a straightedge, find the intersection point of the total
horizontal and total vertical values. The intersection point
must fall within the shaded area for the flywheel housing
concentricity to be within specification.
Using the total horizontal and total vertical values from the
previous example, the intersection point falls within the
shaded area. Therefore, the flywheel housing
concentricity is within specification.
NOTE: Make sure to use the correct total indicator
reading (TIR) specifications for the flywheel housing being
measured when comparing measurements.
