5.6 Disassembling DPF assembly
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 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 from.
• Since the engine operating time is recorded in
the engine ECU, check the operating time by
connecting the service tool (Diagmaster).
• When removing the muffler full assembly (DPF),
make sure that the exhaust gas temperature
sensor, differential pressure sensor, and
differential pressure pipe do not make contact
with surrounding parts.
