Cylinder Block Inspection

Cylinder Block Inspection
1. Measure the cylinder bore at the top and bottom. Verify the cylinder bore is within the wear limit. The difference indicates the cylinder taper; bore the cylinder to the next oversize.





2. Measure the cylinder bore in two directions. The difference is the out-of-round. Verify the out-of-round is within the wear limit and bore the cylinder to the next oversize limit.





3. Use a straightedge SST 303-D039 or equivalent and a feeler gauge to inspect the head gasket surface for flatness. If the cylinder block is distorted, resurface the cylinder block within specification.
^ The head gasket surface is measured in six straight line directions for flatness.
