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.

5. Cylinder bore size is determined by adding pi
ston-to-bore clearance to piston diameter (A).
6. Install main bearing caps, and tighten to the specified torque. Otherwise, cylinder bores may be distorted after boring.
7. Cut cylinder bores. •When any cylinder needs boring, all ot her cylinders must also be bored.
• Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter
at a time.
8. Hone cylinders to obtain specified piston-to-bore clearance.
9. Measure finished cylinder bore for out-of-round and taper. •Measurement should be done after cylinder bore cools down.
CRANKSHAFT
1. Check the crankshaft main and pin journals for scoring, wear, or
cracks.
2. Measure the journals for taper and out-of-round.
3. Measure crankshaft runout.
a. Place a V-block on a precise flat table to support the journals on the both ends of the crankshaft.
b. Place a dial gauge straight up on the No. 3 journal.
c. While rotating the crankshaft, read the movement of the pointer on the dial gauge.

ferred method.
