left hand compartment above the engine. The
tail pipe exhausts the gases from the upper left
rear corner of the bus. Remove the muffler as

1. Open the muffler access door on the rear
street side of the coach.
2. Remove the band clamps that attach the
tail pipe to the top outlet and the exhaust
pipe to the bottom outlet of the muffler.
Each band clamp is secured by two cap -
screws.
3. Disconnect the tail pipe and the exhaust
pipe from the muffler. Remove the tail
pipe.

which clamps the muffler’s outlet tube.
6. The muffler is heavy. Carefully remove
the muffler from the coach through the
muffler access door opening.
