Disassembly Of Dpf Muffler Full Assembly; D1803-Cr-E4, D1803-Cr-Te4, V2403-Cr-E4, V2403-Cr-Te4 - Kubota D1803-CR-E4 Workshop Manual

DIESEL PARTICULATE FILTER HANDLING MANUAL, WSM

[3] DISASSEMBLY OF DPF 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 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.
NOTE
• 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 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 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.
