9.2 Cleaning DPF

IMPORTANT
• Since the DPF that was dropped or given a
shock cannot be reused even if there is no
damage outwardly, replace it with a new one.
• Be sure to loosen the exhaust gas temperature
sensor tightening
pressure pipe tightening nut with crowfoot
wrench to prevent the damage of the sensor or
pipe.
If it is still hard to loosen, apply the lubricant
spray to threaded portion and soak it with
lubricant.
NOTE
• Always work in the workshop equipped with a
electric lift (including mobile lift).
• Put a product (engine) on a stable ground, and
set the parking brake.
• As the DPF muffler full assembly is hot just
after the engine shutdown, make sure to start
operation after it gets cool.
• Make sure not to let any foreign substances
enter the opening section during the operation.
• Make sure not to damage the DPF muffler full
assembly by falling or impact as it contains a
ceramic filter.
• Before removing the DPF muffler full assembly
from a product (engine), connect the diagnosis
tool (Diagmaster), check the failure history, and
save the project.
• Before removing the DPF for cleaning, keep the
records of the engine serial number, filter comp
(DPF) part number, filter comp (DPF) serial
number, catalyst (DOC) part number, catalyst
(DOC) serial number, and engine operating time,
which are required in preparing the DPF
cleaning order form.
• Since the engine operating time is recorded in
the engine ECU, check the operating time by
connecting the service tool (Diagmaster).
