Judgment of Reuse of Filter Comp (DPF) After Cleaning by
Cleaning Contractor
IMPORTANT
• After the cleaning contractor has cleaned the filter comp
DPF (2), they should measure the quantity of remaining ash
in the following procedure, and evaluate the reusability.
1. After having cleaned the filter comp (DPF) (2), measure the
actual cell depth
(E)
with a pin gauge (1) in the each block
shown in the figure. One cell (The measurement point is not
specified) is measured in each block.
2. If the actual cell depth
(E)
is less than the allowable limit, the
DPF (2) cannot be reused.
If the DPF (2) is judged as non-reusable, report the result of the
judgment to the customer that requested the filter cleaning via
the service dealer, and replace the DPF (2) with a new one.

NOTE
• Select a metal pin gauge (1) having a wire size slightly
thinner than the cell width (0.60 to 0.80 mm dia., 0.024 to
0.031 in. dia.).
• When the pin gauge (1) is inserted into the cell hole, insert
it by lightly tapping on the gage end with a finger tip.
• If the pin gauge is forcibly pushed in, the pin pierces
through the accumulated ash and it cannot be measured
accurately. So be careful not to push the pin forcibly.
