Cylinder Bore Out-of-Round Measurement Procedure
WARNING: This page is about a different variant/trim than selected.
- Measure both the thrust and non-thrust cylinder diameter 5 mm (0.20 in) below the deck surface using the J 8087 . Record your measurements.
- Calculate the difference between the two measurements. The result will indicate out-of-round at the upper end of the cylinder.
- Measure both the thrust and non-thrust cylinder diameter 102 mm (4.00 in) below the deck surface using the J 8087 . Record your measurements.
- Calculate the difference between the two measurements. The result will indicate out-of-round at the lower end of the cylinder.
- Compare your results with the engine mechanical specifications. If the cylinders exceed these specifications, replace the cylinder block.
