2. Shut down the engine and allow the DPF assembly to cool.
3. Disconnect the negative battery terminal and perform a lock-out / tag-out of the negative battery cable.
4. Remove the DPF module from the generator set.
5. Disassemble the DPF filter section and the DOC.
6. Remove ash from the DPF filter using either a commercially available cleaning system or a vacuum with a
HEPA filter.
7. Using a new gasket (30-00510-63), reassemble the DPF filter section to the DOC. Tighten the v-clamp to
specified torque. Refer to Installation Instructions for specified torques.
8. Reinstall the DPF assembly, with new inlet gasket, into the unit.
9. Properly align and tighten all clamps to specified torques. Refer to Installation Instructions for specified
torques.
10. Remove lock-out / tag-out devices.
11. Reconnect negative battery cable to negative battery terminal.
12. Start the unit in Engine mode and initiate a regeneration. Check back pressure readings on the ECM
Service Tool. Refer to
. If back pressure reading is higher than 120 in/H2O (30 kPa), then the
filter may require additional cleaning or possible replacement.
13. If back pressure reading is higher than 120 in/H2O (30kPa), then filter may require additional cleaning, or
possible replacement.
6.5 Carb Registration and System Labeling
The DPF needs to be registered with CARB using the ARBER website. At any point in time that the DOC is replaced
in the EES, re-registration with CARD is required.
When the Filter Assembly, including DOC and DPF, is installed, a CARB label is provided for each component
(Refer to
). The CARB label will contain relevant information about filter substrate name, serial number
and date of manufacture. The CARB label for DOC is placed on the DOC itself, but a duplicate is also provided to
place on the generator set unit, on the front of the oil pan.
