5.5 Removing 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.
• 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.
• D1803-CR-TIE4, 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 disassembled by the
same way of -E4 and -TE4.
