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 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.
Standard value: 0.05 mm (0.0020 inch)
Limit: 0.1 mm (0.004 inch)
3. If the distortion is excessive, correct within the allowable limit, or replace.
Grinding limit: 0.2 mm (0.008 inch) (includes/combined with cylinder head grinding).
Cylinder block height (when new): 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 oversized) 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
Standard value:
Cylinder I.D.: 6.50 mm (3.4055 inch).
Cylindricity: 0.01 mm (0.0004 inch) or less.
