Revision A
Cleaning and Inspecting the Supply Module Filter
NOTE:
If there is the possibility that contaminated diesel exhaust fluid (DEF) has gone through the DEF supply system, check the
DEF filter prior to discarding the filter.
1. Check the diesel exhaust filter for evidence of contaminated DEF. Use visual and aroma characteristics of the filter to
determine if contaminated fluid has passed through the dosing system.
2. Inspect the diesel exhaust filter for debris.
3. Discard the filter element and the equalizing element.
4. Inspect the aftertreatment DEF dosing unit filter cap for cracks or holes.
5. Check the condition of the threads on the aftertreatment DEF dosing unit cap.
6. If threads are damaged, replace the aftertreatment DEF dosing unit cap.
7. If cap threads are damaged, inspect the aftertreatment DEF dosing unit threads.
8. If threads of aftertreatment DEF dosing unit are damaged, replace the entire aftertreatment DEF dosing unit.
9. Clean the aftertreatment DEF dosing unit cap and threads on the supply module with warm water and clean cloth.

1. Slide the DEF filter equalizing element (A) into the DEF filter
cartridge (B).
2. Insert the assembly into the aftertreatment DEF dosing
unit (C).
3. Install cap (D) and torque to 20 Nm (15 lbf·ft).
NOTE:
The aftertreatment DEF dosing system will not prime until
the correct selective catalytic reduction catalyst (SCR)
temperatures are reached. To verify that there are no DEF
leaks, test drive the windrower for a minimum of
15 minutes to get the SCR system up to temperature.
4. Operate the engine and check for leaks.
