head facing the front of the engine.
CAUTION:
 Be careful not to damage matching surface with con-
necting rod cap.
 Be careful not to damage the cylinder wall and crank-
shaft pin, resulting from an interference of the connect-
ing rod big end.

[SST: KV10112100] (A) or protractor. Avoid judgment by
visual inspection without the tool.
 After tightening connecting rod bolts, make sure that crankshaft rotates smoothly.
 Check the connecting rod side clearance. Refer to EM-108, "
Inspection".

CRANKSHAFT END PLAY
 Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
 If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE
 Measure the side clearance between connecting rod and crank-
shaft arm with a feeler gauge (A).
 If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the standard, replace crank-
shaft also.

Measure the outer diameter of piston pin with a micrometer.
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)
 If oil clearance is out of the standard, replace piston and piston pin assembly.
PISTON RING SIDE CLEARANCE
 Measure the side clearance of piston ring and piston ring groove
with a feeler gauge.
 If the measured value exceeds the limit, replace piston ring, and
measure again. If it still exceeds the limit, replace piston also.
PISTON RING END GAP
 Make sure that cylinder bore inner diameter is within the specifica-
tion. Check "Cylinder Bore Inner Diameter".
 Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and measure
piston ring end gap with a feeler gauge.

 If the measured value is out of the standard, replace connecting rod assembly and/or piston and piston pin
assembly.
 If replacing connecting rod assembly, use "CONNECTING ROD BEARING OIL CLEARANCE" to select con-
necting rod bearing.
CYLINDER BLOCK TOP SURFACE DISTORTION
 Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.
 Measure the distortion on the cylinder block upper face at some
different points in six directions with a straight edge and a feeler
gauge.
 If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
 Install main bearing cap without main bearings installed, and tighten main bearing cap bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the position shown in the figure [5 mm (0.196 in) rear-
ward from main bearing housing front side end surface) in the 2
directions as shown in the figure. The smaller one is the measured
value.
 If out of the standard, replace cylinder block and main bearing
caps as an assembly.
NOTE:
These components cannot be replaced as a single unit, because they were processed together.
