[4]  JUDGMENT OF REUSE OF DPF FILTER COMPLETE BEFORE 

CLEANING

IMPORTANT

• Before ordering to a cleaning contractor, follow the procedures below to make a judgment on whether the

separated DPF filter complete is reusable.

Judgment of Reuse by Service Dealer
1. Check to see that the surface of the removed DPF filter

complete on the exhaust gas outlet side is not darkened.

2. Check whether there is no crack or loss of the sealing part of the

cell holes on both ends of the filter (inlet side and outlet side).
If the number of missing sealing parts exceeds the allowable
limit, the filter complete cannot be reused even after cleaning.

3. Check whether there is no crack and loss of the ceramics

element. 
If there are any cracks or losses of the ceramics element, the
DPF filter complete cannot be reused even if it is cleaned. 

4. If it is judged that the DPF filter complete is not reusable, report

the result of the evaluation to the customer that requested the
filter cleaning, and replace the DPF filter complete with a new
one.

[5]  PREPARATION OF "AFTER-TREATMENT DEVICE EXCHANGE 

REPORT FORM"

IMPORTANT

• When replacing the DPF filter complete with a new one because the DPF filter complete cannot be reused,

make sure to prepare the "After-Treatment Device Exchange Report Form" and to send the report form to
KUBOTA sales company.

Preparation of "After-Treatment Device Exchange Report
Form"
1. Fill out the attached form (After-Treatment Device Exchange

Report Form).

2. Send the report form to a service representative of KUBOTA

sales company.
