Cylinder Block Assembly: Testing and Inspection

1. 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) or less
Limit: 0.1 mm (.004 inch)
2. If the distortion is excessive, correct within the allowable limit or replace.
Grinding limit: 0.2 mm (0.008 inch)
The total thickness of the stock allowed to be removed from cylinder block and mating cylinder head 0.2 mm (0.008 inch) at maximum.
Cylinder block height (when new): 263.5 mm (10.374 inch)
3. Check the cylinder walls for scratches and seizure. If defects are evident, correct (bored to oversize) or replace.





4. Using a cylinder gauge, measure the cylinder bore and cylindricity. If worn badly, correct the cylinder to an oversize and replace the piston and piston rings. Measure at the points shown in illustration.
Standard value:
Cylinder inner diameter: 81.0 mm (3.19 inch)
Out-of-roundness and taper of cylinder bore: 0.01 mm (.0004 inch) or less.
