Removal (Fig. 5)
CAUTION
The engine and exhaust system may be hot. To
avoid possible burns, allow the engine and ex-
haust system to cool before working on the ex-
haust system.
1. Park machine on a level surface, lower cutting unit
(or implement), stop engine, engage parking brake and
remove key from the ignition switch.
2. Unlatch and raise hood.
3. Remove two (2) carriage screws and flange lock nuts
that secure the muffler to the muffler bracket (Fig. 6).
4. Remove four (4) flange nuts from the exhaust man-
ifold studs. Separate muffler flange from the engine ex-
haust manifold. Remove muffler from the machine.
5. Remove exhaust gasket. Replace gasket if dam-
aged or torn.
Installation (Fig. 5)
NOTE: Make sure muffler flange and engine exhaust
manifold sealing surfaces are free of debris or damage
that may prevent a tight seal.
1. Place exhaust gasket on the engine exhaust man-
ifold.
IMPORTANT: Finger tighten all fasteners before se-
curing the muffler to the muffler bracket so there is
no preload on the exhaust system.
2. Position muffler flange to the engine exhaust man-
ifold and loosely install four (4) flange nuts.
3. With the muffler flange tight to the engine exhaust
manifold (no gaps visible), position muffler so that muf-
fler is tight against muffler bracket (no gaps visible).
4. Tighten four (4) flange nuts to secure muffler flange
to exhaust manifold. Torque flange nuts 17 to 21 ft–lb
(23 to 28 N–m).
5. Check that clearance between muffler and muffler
bracket is less than 0.015" (0.4 mm). If necessary, re-
peat steps 3 and 4 above. Once clearance is less than
0.015" (0.4 mm), secure muffler to the muffler bracket by
tightening two (2) carriage screws and flange lock nuts
(Fig. 6). Torque lock nuts from 38 to 48 in–lb (4.3 to 5.4
N–m).
6. Close and latch hood.
