[9] JUDGMENT OF REUSE OF DPF FILTER COMP AFTER
CLEANING (REFERENCE)
IMPORTANT
• After the cleaning contractor has cleaned the DPF filter comp, measure the quantity of remaining ash in
the following procedure, and evaluate the reusability.
Judgment of Reuse by Cleaning Contractor
1. After having cleaned the DPF filter component, measure the
depth of ash (depth of remaining ash) with a pin gauge in the
each block shown in the figure. One cell (The measurement
point is not specified) is measured in each block.
Model
V3800
V6108
2. If the depth of ash (remaining depth) is less than the allowable
limit, the DPF filter comp cannot be reused.
If the DPF filter comp 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 filter comp
with a new one.
NOTE
• Select a metal pin gauge 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 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 deposited ash and it cannot be measured
accurately. So use caution not to push the pin forcibly.
