a. Tighten the connecting rod bolts using Tool (A) as follows:
Apply engine oil to the threads and seats of the connecting rod
bolts.
CAUTION:
Check tightening angle. Do not judge angle by visual
inspection.
• After tightening connecting rod bolts, check that crankshaft rotates smoothly.
• Check the connecting rod side clearance. Refer to
14. Install knock sensor (1).
• Install knock sensor with connector facing 180
° +/- 15° (a) as
shown.
CAUTION:
• Do not tighten bolts while holding connector.
• If any impact by dropping is applied to knock sensor,
replace it with a new one.
NOTE:
• Check that there is no foreign material on the cylinder block
mating surface and the back surface of knock sensor.
• Check that knock sensor does not interfere with other parts.
15. Install crankshaft position sensor (POS).
16. Assembly of remaining components is in the reverse order of disassembly.

CRANKSHAFT END PLAY
• Measure clearance between thrust bearings and crankshaft arm
when crankshaft is moved fully forward or backward using suitable
tool (A).
• If measured value exceeds limit replace thrust bearings and mea-
sure again. If it still exceeds limit replace crankshaft.
CONNECTING ROD SIDE CLEARANCE
• Measure side clearance between connecting rod and crankshaft
arm using suitable tool (A).
• If measured value exceeds limit replace connecting rod and mea-
sure again. If it still exceeds limit replace crankshaft.

CYLINDER BLOCK
PISTON TO PISTON PIN OIL CLEARANCE
Piston Pin Hole Diameter
• Measure inner diameter of piston pin hole using suitable tool (A).
Piston Pin Outer Diameter
• Measure outer diameter of piston pin using suitable tool (A).
Piston to Piston Pin Oil Clearance
• (Piston to piston pin oil clearance) = (Piston pin hole diameter) - (Piston pin outer diameter)
• If oil clearance value exceeds the limit replace piston and piston pin assembly.
NOTE:
Piston is available together with piston pin as assembly.
PISTON RING SIDE CLEARANCE
• Measure side clearance of piston ring and piston ring groove using
suitable tool (A).
• If measured value exceeds limit replace piston ring and measure
again. If value still exceeds the limit replace piston.

CONNECTING ROD BIG END DIAMETER
• Install connecting rod cap (1) without connecting rod bearing
installed and tighten connecting rod bolts. Refer to
.
• Measure inner diameter of connecting rod big end using suitable
tool.
• If measured value exceeds standard replace connecting rod assembly.

CYLINDER BLOCK
• Measure outer diameter of piston pin using suitable tool (A).
Connecting Rod Bushing Oil Clearance
• (Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) - (Piston pin outer diame-
ter)
• If measured value exceeds standard replace connecting rod assembly and/or piston and piston pin assem-
bly.
CYLINDER BLOCK TOP SURFACE DISTORTION
• Remove gasket on the cylinder block surface and also remove engine oil, scale, carbon and other contami-
nation using suitable tool.
CAUTION:
Do not allow gasket flakes to enter engine oil or engine coolant passages.
• Measure distortion on cylinder block upper face at some different
points in six directions using suitable tools (A/B).
• If measured value exceeds standard replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
• Install lower cylinder block without main bearings installed and tighten lower cylinder block bolts. Refer to
EM-98, "Disassembly and Assembly"
.
• Measure inner diameter of main bearing housing using suitable
tool.
• If measured value exceeds standard replace cylinder block (1) and
lower cylinder block (2) assembly.
NOTE:
Lower cylinder block cannot be replaced as a single unit because it
is machined together with cylinder block.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter
• Measure cylinder bore for wear, out-of-round and taper at six different points on each cylinder using suitable
tool. [(A) and (B) directions at (C), (D), and (E)] [(A) is in longitudinal direction of engine]
