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.

(F)

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.
