Removal (Fig. 10)
1. Park machine on a level surface, stop the engine, en-
gage parking brake and remove the key from the key
switch.
2. Raise cargo bed and support with prop rod.
CAUTION
The engine and exhaust exhaust may be hot. To
avoid possible burns, allow engine and exhaust
system to cool before working on the exhaust
system.
3. Remove exhaust system components as needed us-
ing Figure 10 as a guide. On machines with electronic
fuel injection (EFI) disconnect the oxygen sensor from
the engine wire harness before removing the exhaust
manifold.
4. If removed, discard exhaust gasket and thoroughly
clean flange surface of cylinder head and exhaust mani-
fold.

Installation (Fig. 10)
NOTE: New oxygen sensor threads come pre- coated-
with an anti seize compound. If a previously installed
oxygen sensor is used, apply a small amount of anti-
seize to the threads.
1. If installing an oxygen sensor, do not allow the tip of
the sensor to touch anything as it may become contami-
nated. Tighten from 12.6 to 15.4 ft- lb (17 to 21 N·m).
2. If the exhaust manifold was removed from engine,
install manifold to engine with new gasket. Attach ex-
haust manifold loosely to the engine with removed
flange nuts.
3. Using Figure 10 as a guide, loosely fit all exhaust
system components to vehicle.
4. Tighten all exhaust system fasteners starting at the
engine and working out toward the muffler. During as-
sembly, use fastener torque specifications that are iden-
tified in Figure 10.
5. On machines with electronic fuel injection (EFI) con-
nect the oxygen sensor to the engine wire harness.
6. Lower and secure cargo bed.
