Cylinder Block Assembly: Testing and Inspection

1. Visually check for scratches, rust and corrosion. Use also a flaw detecting agent for the check. If defects are evident, correct, or replace.





2. Using a straight edge and feeler gauge, check the block top surface for warpage. Make sure that the surface is free from gasket chips and other foreign matter.
3. If the distortion is excessive, correct within the allowable limit or replace.
4. Check cylinder walls for scratches and seizure. If defects are evident, correct (bored to oversize) or replace.





5. Using cylinder gauge, measure the cylinder bore and cylindricity. If worn badly, correct cylinder to an oversize and replace piston and piston rings. Measure at the points shown in illustration.
