Filter Comp (DPF) (If necessary)
• Always work in the workshop equipped with a electric hoist
(including mobile hoist).
• 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 ECU,
check the operating time by connecting the service tool
(Diagmaster).
• When installing and removing the muffler full assembly
(DPF), make sure that the temperature sensor, differential
pressure sensor, and differential pressure pipe do not
make contact with surrounding parts.
• Be sure to loosen the temperature sensor tightening nut or
the differential 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.
1. Remove the tube (3), (5) from the differential pressure pipe (4),
(6).
2. Remove the differential pressure sensor (7).
3. Loosen the filter comp (DPF) mounting screw (1), (2) and
remove the filter comp (DPF) (9).
