4. INSTALL FRONT EXHAUST PIPE ASSEMBLY
(a) Check compression springs.
(1) Check the compression springs using vernier
calipers.
Specified length:
38.86 mm (1.5299 in.)
HINT:
If the result is not as specified, replace the
compression spring.
(b) Install the gasket.
(1) Install a new gasket by hand onto the front
exhaust pipe assembly.
(2) Using a plastic hammer and wooden block, tap
in the new gasket until its surface is flush with
the front exhaust pipe.
NOTICE:
• Be careful with the installation direction
of the gasket.
• Do not damage the gasket.
• Do not reuse the gasket.
• To ensure a proper seal, do not use the
exhaust pipe to force the gasket on to the
front exhaust pipe.
(c) Install 2 new gaskets to the front exhaust pipe
assembly.
(d) Install the front exhaust pipe assembly with the 4
nuts.
