Check that the difference between the largest and the smallest diameters in the same vertical plane of each
diameter of each cylinder barrel is within the taper tolerance.

CRANKSHAFT MAIN JOURNAL DIAMETER

Use micrometer to measure crankshaft main journal diameter.

CRANKSHAFT PIN JOURNAL DIAMETER

Use micrometer to measure crankshaft pin journal diameter.

FLYWHEEL ISNPECTION

For a dual mass flywheel which has worked: presence of a free rotation angle. This angle is measured by fix-
ing the primary flywheel and turning the secondary flywheel. The dual mass flywheel free rotation angle must
not exceed 15

°

or 3 cm in linear movement measured on the edge.
