Cylinder Block Assembly: Testing and Inspection

1. Visually check for scratches, rust, and corrosion. Also, use a flaw detecting agent for the check. If defects are evident, correct, or replace.
2. Using a straightedge and feeler gauge, check the block top surface for warpage. Make sure that the surface is free from gasket chips and other foreign matter. The standard value is 0.05 mm (0.0020 inch) and the limit is 0.1 mm (0.004 inch).
3. If the distortion is excessive, correct within the allowable limit or replace. The grinding limit is 0.2 mm (0.008 inch) (includes/combined with cylinder head grinding. The cylinder block height (when new) is 289.9 - 290.1 mm (11.413 - 11.421 inch).
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. The standard value for the cylinder I.D. is 86.5 mm (3.41 inch) and cylindricity is 0.01 mm (0.0004 inch) or less.
