CYLINDER BLOCK DISTORTION
• Using a scraper, remove any old gasket material on the cylinder block surface, and remove any oil, scale, carbon, or other contami-
nation.
CAUTION:
Be careful not to allow gasket fl akes to enter the oil or coolant
passages.
• Measure the distortion on the block upper face at different points in six directions.
• If out of specification, resurfac e the cylinder block. The allowable
amount of resurfacing is dependent on the amount of any cylinder
head resurfacing. The resurfacing limit is [amount of cylinder head resurfacing] + [amount of cylinder head
resurfacing] = 0.2 mm (0.008 in).
INNER DIAMETER OF MAIN BEARING HOUSING
• Install the main bearing caps with the main bearings removed, and tighten the bolts to the specified torque.
• Using a bore gauge, measure the inner diameter of the main bear-
ing housing (A).
• If out of the standard, replace the cylinder block and main bearing caps as an assembly.
NOTE:
These components cannot be replaced as a single unit, because
they were processed together.
PISTON-TO-CYLINDER BORE CLEARANCE
1. Using a bore gauge, measure cylinder bore for wear, out -of-round and taper at (A), (B) and (C). The X axis
is in the longitudinal direction of the engine.
