Diesel Particulate Filter
The diesel particulate filter should be removed
from the system and replaced at the
recommended service interval. If the filter is not
replaced, it will become clogged and increase
exhaust back pressure. As back pressure
increases, engine power and economy decline as
does the ability of the system to remove
undesirable emissions.
SPACE SAVER UNIT
The components reach high temperatures
during use. Ensure that the unit has cooled to
the touch before handling. Failure to heed this
warning may result in severe personal injury.
Removal
1. When the fairing (if present), braces and
steps have been removed to permit access,
remove the lines and sensors connecting the
inlet module to the other modules.
2. Disconnect wiring and sensor connectors
from the DPF and outlet modules. Cut tie
straps securing the lower portion of the DPF
harness to the muffler body. Also, remove
the pressure differential sensor tube that
connects to the outlet module.
3. Using a marker, make alignment marks on
each of the module sections, above and
below each V-band clamp.

4. Remove the lower exhaust V-band clamp
that connects the DPF outlet module to the
exhaust pipe. Also, remove the V-band
clamp that connects the catalyst module to
the filter module.

5. Position a flat surface jack with a very stable
support (such as a transmission jack) under
the base of the DPF.
