Cylinder Block Assembly: Testing and Inspection

1. Clean the upper surface of cylinder block. Using a reliable straightedge and feeler gauge, check the flatness of the cylinder block surface. Check along six positions as shown in figure. The standard is less than 0.03 mm (0.0012 inch). The limit is 0.1 mm (0.004 inch).
2. If out of specification, resurface it. The limit for cylinder block resurfacing is determined by the amount of cylinder head resurfacing.
^ The amount of cylinder head resurfacing is "A".
^ Amount of cylinder block resurfacing is "B".
^ The maximum limit is A + B = 0.2 mm (0.008 inch).
^ Nominal cylinder block height from the crankshaft center is 246.95 - 247.05 mm (9.7224 - 9.7264 inch).
3. If necessary, replace the cylinder block.
