front end (4).
c. Install internal mechanism securing bolt and plate (Service part:
13012 EB30A and 13013 EB30A) (A) and tighten to the speci-
fied torque.
CAUTION:
lDo not loosen idler gear mounting bolt (5).
lOnly use the genuine internal mechanism securing bolt
and plate (A), or the idler gear (2) and (3) will be damaged.
lDo not remove internal mechanism securing bolt and
plate (A) from idler gear (2) and (3) until crankshaft gear
(1) and all of the parts in connection have been installed.
lIf internal mechanism securing bolt and plate (A) is not
installed, internal mechanism of idler gear (2) and (3) will

quantity, fill to the specified level. Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
lUse procedure below to check for fuel leakage.
–Before starting engine, check for fuel leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
lRun engine to check for unusual noise and vibration.
lWarm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
lBleed air from lines and hoses of applicable lines, such as in cooling system.
lAfter cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

CAUTION:
lBe sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance and shape.
lPerform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
lBe careful not to cut your hand on the insulator edge.
REMOVAL
Separate each connection as necessary.
CAUTION:
Do not disassemble main muffler at the portion “A” shown in the figure.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
lAlways replace exhaust gaskets and seal bearings with new ones when reassembling.
lIf insulator is badly deformed, repair or replace it. If deposits such as mud pile up on insulator,
remove them.
lWhen installing insulator avoid large gaps or interference between insulator and each exhaust
pipe.
lRemove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.
lTemporarily 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.
lWhen installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
