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 (A) and feeler
gauge (B).
 If it exceeds the limit, replace cylinder block.
PISTON PROTRUSION
1. Clean the piston head.
2. Turn the crankshaft one turn in its operating direction to bring piston No. 1 close to TDC.
3. Install dial gauge stand set [KV113B0050 (Mot. 252-01) (com-
mercial service tool) or equivalent tool] on the piston.
4. Install dial gauge stand set [KV113B0040 (Mot. 251-01) (com-
mercial service tool) or equivalent tool] equipped with a gauge
on dial gauge stand set [KV113B0050 (Mot. 252-01) (commer-
cial service tool) or equivalent tool], and find TDC.
NOTE:
All measurements must be carried out along the longitudinal
axis of the engine, in order to eliminate any errors due to tilting
of the piston.

CYLINDER BLOCK
 Measure the side clearance of piston ring and piston ring groove
with a feeler gauge (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
 Lubricate with new engine oil to piston (1) and piston ring (2), 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.
CRANKSHAFT MAIN JOURNAL DIAMETER
Use micrometer to measure crankshaft main journal diameter.
CRANKSHAFT PIN JOURNAL DIAMETER
Use micrometer to measure crankshaft pin journal diameter.Standard : Refer to EM-337, "

CAUTION:
• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
 Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
 Be careful not to cut your hand on the heat insulator edge.

2. Disconnect each joint and mounting rubber.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
 Always replace exhaust gaskets and seal bearings with new ones when installing.
 Discard any heated oxygen sensor 2 which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; use a new one.
 Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-
gen sensor thread cleaner and apply anti-seize lubricant (commercial service tool).
 Do not over tighten heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-
sor 2, resulting in the “MIL” coming on.
 Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust leakage.
 Temporarily tighten nuts on the exhaust manifold side and bolts on the vehicle side. Check each part
for unusual interference, and then tighten them to the specified torque.
 When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/left
directions.
Exhaust Manifold to Exhaust Front Tube
1. Securely insert seal bearing (2) into exhaust manifold (1) side in
the direction shown.
 Exhaust front tube (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. Install spring (3), tighten nut (4).
 Be careful that the stud bolt nut does not interfere with the
flanged area ( ).
 Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
Exhaust Front Tube to Center Muffler
1. Securely insert seal bearing (2) into exhaust front tube (1) side
in the direction shown.
 Center muffler (5)
CAUTION:
Be careful not to damage seal bearing surface when install-
ing.
2. With spring (3), tighten bolt (4).
 Be careful that the stud bolt does not interfere with the flanged
area ( ).
 Make sure the spring (3) sits properly on the flange surface by
aligning it to the locator dimples.
InspectionINFOID:0000000001700348
INSPECTION AFTER INSTALLATION
 With the engine running, check exhaust tube joints for exhaust leakage and unusual noise.
 Check to ensure that brackets and mounting rubbers are installed properly and free from undue stress.
Improper installation could result in excessive noise and vibration.
