3-14. EXHAUST SYSTEM
A. GENERAL - The exhaust system consists of a muffler which
connects to the manifold piping of the engine. This system tends to
equalize the pressures at which the exhaust is released, resulting in a
noise reduction. The muffler consists of a sheet-metal cylinder which
contains baffles around which exhaust gases mast circulate before they
are dispelled to atmosphere. The muffler is held in place with 2 cap
screws, with 4 lock washers and 2 nuts. There is a gasket on each side
of the spacer - spacer located between the manifold flange & the muffler
flange (Fig. 3-8).
Refer to Fig. 3-8, and remove muffler.
