CRUSH HEIGHT OF MAIN BEARING
When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-254, "
ASSEMBLY" for the tight-
ening procedure.
If the standard is not met, replace main bearings.
CRUSH HEIGHT OF CONNECTING ROD BEARING
When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to EM-254,
"ASSEMBLY" for the tightening procedure.
If the standard is not met, replace connecting rod bearings.
DRIVE PLATE
Check drive plate and signal plate for deformation or cracks.
CAUTION:
Do not disassemble drive plate.
Do not place drive plate with signal plate facing down.
When handling signal plate, take care not to damage or
scratch it.
Handle signal plate in a manner that prevents it from
becoming magnetized.
If anything is found, replace drive plate.Standard : There must be crush height.
SEM502G
Standard : There must be crush height.

Removal and InstallationNBS005RL
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.
REMOVAL
Disconnect each joint and mounting using power tool.
Remove heated oxygen sensor 2 as follows:
–Using heated oxygen sensor wrench (SST), removal heated
oxygen sensor 2.
CAUTION:
Be careful not to damage heated oxygen sensor 2.
INSTALLATION
Note the following, and install in the reverse order of removal.
When installing, heated oxygen sensor 2 is identified by the color of the connector.
Check for deformation of the grommets (18 and 20 of Components).
Insert the collar (17 of Components) vertically.
Install the collar (5 of Components) with its lower surface horizontal.
Temporarily tighten nuts and bolts when installing exhaust pipe assembly. Tighten them to the specified
torque when connecting the vehicle rear to the vehicle front.
CAUTION:
Always replace exhaust tube gaskets with new ones when reassembling.
Discard any heated oxygen sensor which has been dropped onto a hard surface such as a con-
crete floor; use a new one.
Before installing a new heated oxygen sensor, clean exhaust system threads using the heated
oxygen sensor thread cleaner [commercial service tool: J-43897-18 or J-43897-12], and apply the
anti-seize lubricant (commercial service tool).
Do not over torque heated oxygen sensor. Doing so may cause damage to heated oxygen sensor,
resulting in the “MIL” coming on.
If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.
When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.
Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.
Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle 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.
INSPECTION AFTER INSTALLATION
Make sure clearance between tail tube and rear bumper is even.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
