Fig. 3 Checking piston diameter
- Measure approx. 10 mm (3/8 in.) from bottom edge, at points offset by
90 from piston pin axis. Deviation from nominal size: max. 0.04 mm (0.0016 in.)

Special tools and equipment
Inner bore gauge 50-100 mm (2-4 in.)
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. Fig. 4 Checking cylinder bore
- Measure at three locations diagonally in crosswise direction -A- and
lengthwise direction -B-.
Deviation from nominal size: max. 0.08 mm (0.0031 in.)
