(a)
Using a vernier caliper, measure the free length of the compression spring.
Minimum length: 38.5 mm (1.516 in.)
If the free length is less than the minimum, replace the compression spring.
(b) Install a new gasket to the rear side of the front exhaust pipe.
HINT: Using a plastic-faced hammer, uniformly strike the gasket so that the gasket and front exhaust pipe are properly fit.
NOTICE:
^
Be careful of the installation direction of the gasket.
^
Do not reuse the gaskets.
^
To ensure a proper seal, do not use the tailpipe to force the gasket onto the front exhaust pipe.
