5. Using a marker, make alignment marks on
each of the module sections, above and
below each V-band clamp.

6. Remove the pressure differential tube from
the catalytic filter module.
7. Remove the V-band clamp joining the outlet
module to the filter module.
8. With an assistant and a suitable lifting
device, remove the outlet module from the
DPF filter module.

9. Remove the V-band clamp joining the DPF
filter module to the catalytic filter module.
10. Separate the DPF filter module from the
catalytic filter module and discard the
gasket.
11. Inspect and replace the V-band clamps
showing galled threads, cracks or heat
damage. Clean the exposed gasket
surfaces.
Installation
1. Install a new gasket between the catalytic
filter module and the DPF filter module.
2. Align the locator tab located on the bottom of
the DPF filter module with the slot located in
the top of the catalytic filter module. Install
the DPF filter module onto the catalytic filter
module and secure the modules together
using a V-band clamp tightened to
specification.
3. Install a new gasket between the outlet
module and the DPF filter module.
4. With assistance, use a suitable lifting device
to install the outlet module onto the DPF
filter module. Ensure that the differential
pressure tube does not become damaged
during outlet module installation.
Make sure the high-temperature gasket remains
in place and has not become dislodged.
