Differential Pressure Pipe (In the event of need for
replacement)

When the differential pressure pipe is removed or has to be

replaced because it is damaged, follow the procedure given below.
1. Clean the screw parts and apply anti seize agent (NEVER

SEEZ made by Bostik, Grade: Pure nickel special grade).

2. Use caution not to make a mistake in assembling the differential

pressure pipes (1) and (2).

3. Install the differential pressure pipe (1) and (2) with the specified

torque.

Differential Pressure Sensor
1. Install the differential pressure sensor (3).
2. Connect the each tube with differential pressure pipe (1) and

(2), and fix the tube with a clamp surely.
NOTE

• If there are the damage or a crack in the tube, replace the

tube with a new one.

IMPORTANT

• Visually check if there is no damage (ceramic crack or damage) with the cleaned and returned DPF filter

complete. 

DOC Catalyst Complete, DPF Filter Complete and DPF Outlet
Body
1. Replace the gaskets (5), (6), (7) with new ones.
2. Clean the mounting surface of each flange.
3. Assemble the components temporary by arranging the DOC

catalyst complete (4), DPF collar (3), DPF filter complete (2),
and DPF outlet body (1).

4. Tighten all the screws evenly with the specified torque.

NOTE

• Assemble the DPF filter complete (2) in the right direction

by referring to the arrow (8) on the side showing the flow of
exhaust gas.

Exhaust Temperature Sensor (In the event of need for
replacement)

When the exhaust temperature sensor is removed or has to be

replaced because it is damaged, follow the procedure given below.
1. Clean the screw parts and apply anti seize agent (NEVER

SEEZ made by Bostik, Grade: Pure nickel special grade).

2. Install the exhaust temperature sensor T0 (3), T1 (2), and T2 (1)

from the exhaust inlet side (catalyst complete side) sequentially.

3. Install each exhaust temperature sensor with the specified

torque.
NOTE

• Anti seize agent is already applied to the screw parts of

new exhaust temperature sensor.
So, it is not necessary to apply it when replacing new ones.
