haust system.
1. Park machine on a level surface, lower cutting unit,
stop engine, engage parking brake and remove key
from the ignition switch.
2. Unlatch and raise hood.
3. Support muffler to prevent it from falling.
4. Remove flange head screw (item 7) and flange nut
that secure the muffler to the muffler support (item 6).
5. Remove four (4) flange nuts from the exhaust man-
ifold studs.

Installation (Fig. 3)
IMPORTANT: If exhaust studs were removed from
engine cylinder head, thoroughly clean threads in
head and apply Loctite #277 (or equivalent) to stud
threads before installing studs into head.
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 new exhaust gasket on the engine exhaust
manifold.
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), slide and rotate muffler until
top of muffler bracket is flush with rear frame tube with
no tension on muffler flex joint.
4. Tighten four (4) flange nuts to secure muffler flange
to exhaust manifold. Torque flange nuts 17 to 21 ft−lb
(24 to 28 N−m).
5. Secure muffler to the frame by tightening two (2) cap
screws (item 4) and flange nuts making sure that muffler
flex joint does not deform (Fig. 4). Torque cap screws
from 27 to 33 ft−lb (37 to 44 N−m). If flex joint does de-
