Removal (Fig. 3) Installation (Fig. 3)
CAUTION
The muffler guard and exhaust system may be
hot. To avoid possible burns, allow the engine
and exhaust components to cool before working
on the exhaust system.
1. Park the machine on a level surface, fully raise the
coring head and stop the engine. Remove the key from
the ignition switch.
2. Raise lock–up brackets on each side of machine and
lower
coring head until it rests on brackets.
3. Remove fasteners that secure muffler guard to ma-
chine. Remove muffler guard from machine.
4. Remove four (4) self tapping screws (item 12) that

r
emove four (4) cap screws (item 17) and lock washers
(item 16) from the engine. Separate the exhaust tubes
from the engine.
7. Remove exhaust gaskets (not shown).
IMPORTANT: Finger tighten all exhaust system
fasteners
before securing so there is no preload on
exhaust components.
NOTE: If exhaust tubes were removed, make sure ex-
haust tube flanges and engine sealing surfaces are free
of debris or damage that may prevent a tight, leak–free
seal.
1. If exhaust tubes were removed, position exhaust
gaskets between the engine and the exhaust tube
flanges. Make sure that gaskets are positioned correct-
ly. Install four (4) cap screws with lock washers finger
tight to keep exhaust tubes and gaskets in position.
