Removal (Fig. 6)
1. Park machine on a level surface, lower cutting
decks, stop engine, engage parking brake and remove
key from the ignition switch. Raise and support hood.
CAUTION
The muffler and exhaust pipe may be hot. To
avoid possible burns, allow the engine and ex-
haust system to cool before working on the ex-
haust system.
2. Remove exhaust system using Figure 6 as a guide.
Installation (Fig. 6)
NOTE: Make sure muffler flange and exhaust manifold
sealing surfaces are free of debris or damage that may
prevent a tight seal.
1. Place new muffler gasket on the exhaust manifold.
2. If muffler support bracket (item 7) was removed, se-
cure it to engine with removed fasteners.
IMPORT ANT: Finger tighten all exhaust system fas-
teners before tightening so that there is no preload
on the exhaust system due to exhaust system as-
sembly.
3. Install exhaust systemcomponents to the engine us-
ing Figure 6 as a guide. Finger tighten all fasteners until
all exhaust system components have been installed.
4. Tighten exhaust system fasteners inthe followingor-
der:
A. Lift muffler as much as holes in muffler support
bracket (item 7) will allow . T ighten flange nuts (item
6) to secure muffler to support bracket.
B. Tighten flange nuts (item 3) to secure exhaust
header (item 13) to engine flange using order shown
in Figure 7.
C. Tighten hex nuts (item 10) to secure upper clamp
(item 11).
D. If tail pipe bracket (item 9) was removed, tighten
flange head screws (item 14) to secure bracket to
engine.
E. Tighten flange nuts (item 12) to secure lower
clamp (item 17).
F. Tighten fasteners (items 8 and 12) to secure tail
pipe brackets (items 9 and 16).
