Tooling (A) for every 90 degrees.
Note: During the check, keep the crankshaft pressed
toward the front of the engine in order to remove any
end clearance.
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.
