Checking cylinder bore

1 - Approx. 10 mm from top

2 - Center

3 - Approx. 10 mm from bottom

A - Across cylinder block (perpendicular to
crankshaft)

B - In line with cylinder block (parallel to
crankshaft)

CAUTION!
DO NOT have the cylinder block mounted to the assembly stand
while measuring the cylinder bores. The block is deformed by its
own weight under these conditions and this stress will result in false
measurements that are not accurate after the tension has been
relieved. - Measure diagonally at three points in transverse direction -A- and in
longitudinal direction -B-.

Use internal dial gauge 50-100 mm (2-4 in.)
Maximum deviation from nominal dimension: 0.08 mm (0.0031 in.)
