1. Assemble the body (DPF outlet) (1), filter comp
(DPF) (4) and catalyst (DOC) (5) and loosely
tighten the DPF mounting bracket (3).
NOTE
• Assemble the body (DPF outlet) (1), filter
comp (DPF) (4) catalyst (DOC) (5) and DPF
stay 1 according to the each alignment mark
put on before disassembling.
• Replace the gasket (2) with a new one.

6.40 Installing muffler full assembly
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.
• D1803-CR-TIE4 and V2403-CR-TIE4 have DOC
core instead of DPF core, and do not have the
sensors for DPF.
But the muffler canning same as other models.
Therefore, the mufflers of D1803-CR-TIE4 and
V2403-CR-TIE4 could be assembled by the
same way of -E4 and -TE4.
NOTE
• Put a product (engine) on a stable ground, and
set the parking brake.
• Make sure not to let any foreign substances
enter the opening section during the operation.
• Make sure not to damage the muffler full
assembly by falling or impact as it contains a
ceramic filter.
• When installing the muffler full assembly (DPF),
make sure that the exhaust gas temperature
sensor,
differential
differential pressure pipe do not make contact
with surrounding parts.
• Replace the gasket with a new one.
• If the differential pressure tube is damaged or
cracked, replace it.
• When replacing the differential pressure pipe,
apply a anti-seize & lubricating compound
(Bostik, NEVER SEEZ, Pure Nickel Special
Grade), and then attach it to its correct position.
• When replacing the exhaust gas temperature
sensor, check that it is coated with anti-seize &
lubricating compound, and then attach it to its
correct position.
• Tighten bolts and nuts to their specified torque.
Also tighten the exhaust gas temperature
sensor
tightening
pressure pipe tightening nut to the specified
torque with crowfoot wrench.
• After attaching the assembly, start the engine
and make sure that there are no gas leaks.
Tools required
• Anti-seize & lubricating compound (Bostik, NEVER
SEEZ, Pure Nickel Special Grade)
• Crowfoot wrench
