C3.8 DPF
Illustration 14 g06047943
When the pin gauge is inserted into the cell hole, insert the gauge by lightly tapping on the pin with your finger tip. If the pin is pushed in by force, the pin can pierce through the ash and there would not be an accurate measurement.
After the DPF filter is cleaned, measure the depth of ash (depth of remaining ash) in 21 locations with a pin gauge of 0.5 mm to 1.0 mm in diameter, which is slightly less than the cell width at the positions.The minimum remaining ash depth is 106 mm (4.2 inch).The maximum depth is 140 mm (5.5 inch).
Table 2
Measurement Locations 21 Places
A 57 mm (2.2 inch)
B 57 mm (2.2 inch)
C 10 mm (0.4 inch)
D 35 mm (1.4 inch)
E 138 mm (5.4 inch)
F 35 mm (1.4 inch)
G 226 mm (8.9 inch)
If the depth of ash is out of the permissible range, the DPF filter cannot be reused. Replace the DPF filter with a new one.C3.3B DPF
Illustration 15 g03617080
When the pin gauge is inserted into the cell hole, insert the gauge by lightly tapping on the pin with your finger tip. If the pin is pushed in by force, the pin can pierce through the ash and there would not be an accurate measurement.
After the DPF filter is cleaned, measure the depth of ash (depth of remaining ash) in 25 locations with a pin gauge of 0.6 mm to 0.8 mm in diameter.C3.8 & C3.3B Engines - The minimum remaining ash depth is 119 mm (4.7 inch).
If the depth of ash is out of the permissible range, the DPF filter cannot be reused. Replace the DPF filter with a new one.C2.4 DPF
Illustration 16 g06047315
After the DPF filter is cleaned, measure the depth of ash (depth of remaining ash) in 16 locations with a pin gauge of 0.6 mm to 0.8 mm in diameter.C2.4 Engines (Naturally Aspirated) - The minimum remaining ash depth is 102 mm (4.0 inch).C2.4 Engines (Turbo) - The minimum remaining ash depth is 119 mm (4.7 inch).
If the depth of ash is out of the permissible range, the DPF filter cannot be reused. Replace the DPF filter with a new one.Assembly of the DPF Canister
Refer to the Disassembly and Assembly Manual, Diesel Particulate Filter - Assemble for the procedure to disassemble the DPF.

(14) Gas flow
Assemble the DPF filter in the right direction by referring to the arrow (14) on the side showing the flow of exhaust gas.
When installing the temperature sensor and differential pressure pipe, apply 4C-5599 Anti-Seize Compound to the threads.Note: Itis recommended to replacethe two differential pressure hoses.
If the engine is installed in the machine, refer to the machines Engine Supplement, Diesel Particulate Filter - Remove and Install for the procedure to install the DPF.Soot Load
The soot load reset should only be performed after the DPF is cleaned or a new DPF is installed. If the Soot Load Reset is performed any other times, soot load could cause the DPF to crack
