CYLINDER BLOCK

• If oil clearance is out of the standard, replace piston and piston pin assembly.

• When replacing piston and piston pin assembly. Refer to

NOTE:

• Piston is available together with piston pin as assembly.

• Piston pin (piston pin hole) grade is provided only for the parts installed at the factory. For service parts, no

grades can be selected. Only grade “0” is available.

PISTON RING SIDE CLEARANCE

• Measure the side clearance of piston ring and piston ring groove

with a suitable tool (A).

• 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

• Check that cylinder bore inner diameter is within specification. Refer to “PISTON TO CYLINDER BORE

CLEARANCE”.

• Lubricate piston (1) and piston ring (2) with new engine oil and

then insert (A) piston ring until middle of cylinder (B) with piston,

and measure piston ring end gap with a feeler gauge (C).

• If the measured value exceeds the limit, replace piston ring, and

measure again. If it still exceeds the limit, replace cylinder block.

CONNECTING ROD BEND AND TORSION

• Check with a connecting rod aligner.

• If it exceeds the limit, replace connecting rod assembly.

< UNIT DISASSEMBLY AND ASSEMBLY >

[HR16DE]

• Install connecting rod cap (1) without connecting rod bearing

installed, and tightening connecting rod cap bolts to the specified

torque. Refer to

EM-94, "Exploded View"

• Measure the inner diameter (B) of connecting rod big end with a

suitable tool.

• If out of the standard, replace connecting rod assembly.

CONNECTING ROD BUSHING OIL CLEARANCE

Connecting Rod Bushing Inner Diameter

Measure the inner diameter of connecting rod bushing with a suit-

able tool (A).

Piston Pin Outer Diameter

Measure the outer diameter of piston pin with a micrometer (A).

Connecting Rod Bushing Oil Clearance

(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-

ter)

• If the measured value is out of the standard range, replace connecting rod assembly and/or piston and pis-

ton pin assembly.

• If replacing piston and piston pin assembly. Refer to

EM-122, "Cylinder Block"

• If replacing connecting rod assembly. Refer to

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 particles to enter engine oil or engine coolant passages.

CYLINDER BLOCK

• Measure the distortion on the cylinder block upper face at different

points in six directions with a suitable tool (A) and (B).

• 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

• Measure the inner diameter of main bearing housing with a suitable tool.

• Measure the position shown [5 mm (0.20 in)] backward from main

bearing housing front side in the 2 directions as shown. The

smaller one is the measured value.

• If out of the standard, replace cylinder block and main bearing

caps assembly.

NOTE:

Main bearing caps cannot be replaced individually, because they are machined together with cylinder block.

PISTON TO CYLINDER BORE CLEARANCE

Cylinder Bore Inner Diameter

• Using a suitable tool, measure the cylinder bore for wear, out-of-

round and taper at six different points on each cylinder. [(A) and (B)

directions at (C), (D), and (E)] [(A) is in longitudinal direction of

engine]

NOTE:

When determining cylinder bore grade, measure the cylinder bore

(B) direction at (D) position.

• If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall,

replace cylinder block.

NOTE:

Oversize piston is not available.
