Disassembly and assembly

The muffler, catalytic converter/muffler, and die-
sel particulate filter will become extremely hot
during engine operation. A hot muffler, catalytic
converter/muffler and diesel particulate filter can
cause serious burns. Allow adequate cooling
time before working on or near the muffler, cata-
lytic converter/muffler and diesel particulate
filter.
NOTICE
Do not strike any part of the assembly of the Diesel
Particulate Filter (DPF). Do not allow any object to
contact the internal element of the DPF. If the internal
element of the DPF becomes damaged, the assem-
bly must be replaced.

Typical example
1. If necessary, remove the Original Equipment
Manufacturer's (OEM) exhaust tube assembly
from outlet (6). Refer to the OEM for the correct
procedure.
2. Make temporary alignment marks on DPF (4) and
clamps (5) in Positions (A), (B), (C) and (D) in
order to ensure that the DPF is installed in the
original position.
3. If the DPF is installed onto the flywheel housing,
install Tooling (A) in Position (E) in order to
maintain correct alignment of flexible exhaust pipe
assembly (12).
4. Disconnect the flexible exhaust pipe assembly
(12). Refer to Disassembly and Assembly,
“Flexible Exhaust Pipe - Remove and Install” for
the correct procedure.
Note: Do not remove the bellows protector prior to
installing the flexible exhaust pipe assembly.
5. Make a temporary mark on Diesel Particulate Filter
(DPF) (4) in order to show the direction of the flow
for the exhaust gases.
6. Disconnect the wiring harness from connection (1)
for temperature sensor (2).
Note: Make temporary identification marks on all
connections for assembly purposes.
7. Disconnect the wiring harness from connection
(11) for temperature sensor (3)
